-
--------------------------------------------------------------------------------
-
-## 4.1 The ObjectStreamClass Class
-
-The `ObjectStreamClass` provides information about classes that are saved in a
-Serialization stream. The descriptor provides the fully-qualified name of the
-class and its serialization version UID. A `SerialVersionUID` identifies the
-unique original class version for which this class is capable of writing
-streams and from which it can read.
-
-```
-package java.io;
-
-public class ObjectStreamClass
-{
- public static ObjectStreamClass lookup(Class cl);
-
- public static ObjectStreamClass lookupAny(Class cl);
-
- public String getName();
-
- public Class forClass();
-
- public ObjectStreamField[] getFields();
-
- public long getSerialVersionUID();
-
- public String toString();
-}
-```
-
-The `lookup` method returns the `ObjectStreamClass` descriptor for the
-specified class in the virtual machine. If the class has defined
-`serialVersionUID` it is retrieved from the class. If the `serialVersionUID` is
-not defined by the class, it is computed from the definition of the class in
-the virtual machine. *I*f the specified class is not serializable or
-externalizable, *null* is returned.
-
-The `lookupAny` method behaves like the `lookup` method, except that it returns
-the descriptor for any class, regardless of whether it implements
-`Serializable`. The `serialVersionUID` of a class that does not implement
-`Serializable` is *0L.*
-
-The `getName` method returns the name of the class, in the same format that is
-used by the `Class.getName` method.
-
-The `forClass` method returns the `Class` in the local virtual machine if one
-was found by `ObjectInputStream.resolveClass` method. Otherwise, it returns
-*null*.
-
-The `getFields` method returns an array of `ObjectStreamField` objects that
-represent the serializable fields of this class.
-
-The `getSerialVersionUID` method returns the `serialVersionUID` of this class.
-Refer to [Section 4.6, "Stream Unique
-Identifiers"](#stream-unique-identifiers). If not specified by the class, the
-value returned is a hash computed from the class's name, interfaces, methods,
-and fields using the Secure Hash Algorithm (SHA) as defined by the National
-Institute of Standards.
-
-The `toString` method returns a printable representation of the class
-descriptor including the name of the class and the `serialVersionUID`.
-
-## 4.2 Dynamic Proxy Class Descriptors
-
-ObjectStreamClass descriptors are also used to provide information about
-dynamic proxy classes (e.g., classes obtained via calls to the getProxyClass
-method of java.lang.reflect.Proxy) saved in a serialization stream. A dynamic
-proxy class itself has no serializable fields and a serialVersionUID of 0L. In
-other words, when the Class object for a dynamic proxy class is passed to the
-static lookup method of ObjectStreamClass, the returned ObjectStreamClass
-instance will have the following properties:
-
-- Invoking its getSerialVersionUID method will return 0L.
-- Invoking its getFields method will return an array of length zero.
-- Invoking its getField method with any String argument will return null.
-
-## 4.3 Serialized Form
-
-The serialized form of an ObjectStreamClass instance depends on whether or not
-the Class object it represents is serializable, externalizable, or a dynamic
-proxy class.
-
-When an `ObjectStreamClass` instance that does not represent a dynamic proxy
-class is written to the stream, it writes the class name and
-`serialVersionUID`, flags, and the number of fields. Depending on the class,
-additional information may be written:
-
-- For non-serializable classes, the number of fields is always zero. Neither
- the `SC_SERIALIZABLE` nor the `SC_EXTERNALIZABLE` flag bits are set.
-
-- For serializable classes, the `SC_SERIALIZABLE` flag is set, the number of
- fields counts the number of serializable fields and is followed by a
- descriptor for each serializable field. The descriptors are written in
- canonical order. The descriptors for primitive typed fields are written
- first sorted by field name followed by descriptors for the object typed
- fields sorted by field name. The names are sorted using `String.compareTo`.
- For details of the format, refer to [Section 6.4, "Grammar for the Stream
- Format"](protocol.html#grammar-for-the-stream-format).
-
-- For externalizable classes, flags includes the `SC_EXTERNALIZABLE` flag,
- and the number of fields is always zero.
-
-- For enum types, flags includes the `SC_ENUM` flag, and the number of fields
- is always zero.
-
-When an ObjectOutputStream serializes the ObjectStreamClass descriptor for a
-dynamic proxy class, as determined by passing its Class object to the
-isProxyClass method of java.lang.reflect.Proxy, it writes the number of
-interfaces that the dynamic proxy class implements, followed by the interface
-names. Interfaces are listed in the order that they are returned by invoking
-the getInterfaces method on the Class object of the dynamic proxy class.
-
-The serialized representations of ObjectStreamClass descriptors for dynamic
-proxy classes and non-dynamic proxy classes are differentiated through the use
-of different typecodes (`TC_PROXYCLASSDESC` and `TC_CLASSDESC`, respectively);
-for a more detailed specification of the grammar, see [Section 6.4, "Grammar
-for the Stream Format"](protocol.html#grammar-for-the-stream-format).
-
-## 4.4 The ObjectStreamField Class
-
-An `ObjectStreamField` represents a serializable field of a serializable class.
-The serializable fields of a class can be retrieved from the
-`ObjectStreamClass`.
-
-The special static serializable field, `serialPersistentFields`, is an array of
-`ObjectStreamField` components that is used to override the default
-serializable fields.
-
-```
-package java.io;
-
-public class ObjectStreamField implements Comparable {
-
- public ObjectStreamField(String fieldName,
- Class fieldType);
-
- public ObjectStreamField(String fieldName,
- Class fieldType,
- boolean unshared);
-
- public String getName();
-
- public Class getType();
-
- public String getTypeString();
-
- public char getTypeCode();
-
- public boolean isPrimitive();
-
- public boolean isUnshared();
-
- public int getOffset();
-
- protected void setOffset(int offset);
-
- public int compareTo(Object obj);
-
- public String toString();
-}
-```
-
-`ObjectStreamField` objects are used to specify the serializable fields of a
-class or to describe the fields present in a stream. Its constructors accept
-arguments describing the field to represent: a string specifying the name of
-the field, a `Class` object specifying the type of the field, and a `boolean`
-flag (implicitly `false` for the two-argument constructor) indicating whether
-or not values of the represented field should be read and written as "unshared"
-objects if default serialization/deserialization is in use (see the
-descriptions of the `ObjectInputStream.readUnshared` and
-`ObjectOutputStream.writeUnshared` methods in [Section 3.1, "The
-ObjectInputStream Class"](input.html#the-objectinputstream-class) and [Section
-2.1, "The ObjectOutputStream Class"](output.html#the-objectoutputstream-class),
-respectively).
-
-The `getName` method returns the name of the serializable field.
-
-The `getType` method returns the type of the field.
-
-The `getTypeString` method returns the type signature of the field.
-
-The `getTypeCode` method returns a character encoding of the field type ('`B`'
-for `byte`, '`C`' for `char`, '`D`' for `double`, '`F`' for `float`, '`I`' for
-`int`, '`J`' for `long`, '`L`' for non-array object types, '`S`' for `short`,
-'`Z`' for `boolean`, and '`[`' for arrays).
-
-The `isPrimitive` method returns `true` if the field is of primitive type, or
-`false` otherwise.
-
-The `isUnshared` method returns `true` if values of the field should be written
-as "unshared" objects, or `false` otherwise.
-
-The `getOffset` method returns the offset of the field's value within instance
-data of the class defining the field.
-
-The `setOffset` method allows `ObjectStreamField` subclasses to modify the
-offset value returned by the `getOffset` method.
-
-The `compareTo` method compares `ObjectStreamFields` for use in sorting.
-Primitive fields are ranked as "smaller" than non-primitive fields; fields
-otherwise equal are ranked alphabetically.
-
-The `toString` method returns a printable representation with name and type.
-
-## 4.5 Inspecting Serializable Classes
-
-The program *serialver* can be used to find out if a class is serializable and
-to get its `serialVersionUID`.
-
-When invoked on the command line with one or more class names, serialver prints
-the `serialVersionUID` for each class in a form suitable for copying into an
-evolving class. When invoked with no arguments, it prints a usage line.
-
-## 4.6 Stream Unique Identifiers
-
-Each versioned class must identify the original class version for which it is
-capable of writing streams and from which it can read. For example, a versioned
-class must declare:
-
-```
-private static final long serialVersionUID = 3487495895819393L;
-```
-
-The stream-unique identifier is a 64-bit hash of the class name, interface
-class names, methods, and fields. The value must be declared in all versions of
-a class except the first. It may be declared in the original class but is not
-required. The value is fixed for all compatible classes. If the SUID is not
-declared for a class, the value defaults to the hash for that class. The
-`serialVersionUID` for dynamic proxy classes and enum types always have the
-value *0L*. Array classes cannot declare an explicit `serialVersionUID`, so
-they always have the default computed value, but the requirement for matching
-`serialVersionUID` values is waived for array classes.
-
-**Note:** It is strongly recommended that all serializable classes explicitly
-declare `serialVersionUID` values, since the default `serialVersionUID`
-computation is highly sensitive to class details that may vary depending on
-compiler implementations, and can thus result in unexpected `serialVersionUID`
-conflicts during deserialization, causing deserialization to fail.
-
-The initial version of an `Externalizable` class must output a stream data
-format that is extensible in the future. The initial version of the method
-`readExternal` has to be able to read the output format of all future versions
-of the method `writeExternal`.
-
-The `serialVersionUID` is computed using the signature of a stream of bytes
-that reflect the class definition. The National Institute of Standards and
-Technology (NIST) Secure Hash Algorithm (SHA-1) is used to compute a signature
-for the stream. The first two 32-bit quantities are used to form a 64-bit hash.
-A `java.lang.DataOutputStream` is used to convert primitive data types to a
-sequence of bytes. The values input to the stream are defined by the Java
-Virtual Machine (VM) specification for classes. Class modifiers may include the
-`ACC_PUBLIC`, `ACC_FINAL`, `ACC_INTERFACE`, and `ACC_ABSTRACT` flags; other
-flags are ignored and do not affect `serialVersionUID` computation. Similarly,
-for field modifiers, only the `ACC_PUBLIC`, `ACC_PRIVATE`, `ACC_PROTECTED`,
-`ACC_STATIC`, `ACC_FINAL`, `ACC_VOLATILE`, and `ACC_TRANSIENT` flags are used
-when computing `serialVersionUID` values. For constructor and method modifiers,
-only the `ACC_PUBLIC`, `ACC_PRIVATE`, `ACC_PROTECTED`, `ACC_STATIC`,
-`ACC_FINAL`, `ACC_SYNCHRONIZED`, `ACC_NATIVE`, `ACC_ABSTRACT` and `ACC_STRICT`
-flags are used. Names and descriptors are written in the format used by the
-`java.io.DataOutputStream.writeUTF` method.
-
-The sequence of items in the stream is as follows:
-
-1. The class name.
-
-2. The class modifiers written as a 32-bit integer.
-
-3. The name of each interface sorted by name.
-
-4. For each field of the class sorted by field name (except `private static`
- and `private transient` fields:
-
- a. The name of the field.
-
- b. The modifiers of the field written as a 32-bit integer.
-
- c. The descriptor of the field.
-
-5. If a class initializer exists, write out the following:
-
- a. The name of the method, `<clinit>`.
-
- b. The modifier of the method, `java.lang.reflect.Modifier.STATIC`,
- written as a 32-bit integer.
-
- c. The descriptor of the method, `()V`.
-
-6. For each non-`private` constructor sorted by method name and signature:
-
- a. The name of the method, `<init>`.
-
- b. The modifiers of the method written as a 32-bit integer.
-
- c. The descriptor of the method.
-
-7. For each non-`private` method sorted by method name and signature:
-
- a. The name of the method.
-
- b. The modifiers of the method written as a 32-bit integer.
-
- c. The descriptor of the method.
-
-8. The SHA-1 algorithm is executed on the stream of bytes produced by
- `DataOutputStream` and produces five 32-bit values `sha[0..4]`.
-
-9. The hash value is assembled from the first and second 32-bit values of the
- SHA-1 message digest. If the result of the message digest, the five 32-bit
- words `H0 H1 H2 H3 H4`, is in an array of five `int` values named `sha`,
- the hash value would be computed as follows:
-
-```
- long hash = ((sha[0] >>> 24) & 0xFF) |
- ((sha[0] >>> 16) & 0xFF) << 8 |
- ((sha[0] >>> 8) & 0xFF) << 16 |
- ((sha[0] >>> 0) & 0xFF) << 24 |
- ((sha[1] >>> 24) & 0xFF) << 32 |
- ((sha[1] >>> 16) & 0xFF) << 40 |
- ((sha[1] >>> 8) & 0xFF) << 48 |
- ((sha[1] >>> 0) & 0xFF) << 56;
-```

----
-
-- [Example Alternate Implementation of
- java.io.File](#c.1-example-alternate-implementation-of-java.io.file)
-
--------------------------------------------------------------------------------
-
-## C.1 Example Alternate Implementation of java.io.File
-
-This appendix provides a brief example of how an existing class could be
-specified and implemented to interoperate with the existing implementation but
-without requiring the same assumptions about the representation of the file
-name as a *String*.
-
-The system class `java.io.File` represents a filename and has methods for
-parsing, manipulating files and directories by name. It has a single private
-field that contains the current file name. The semantics of the methods that
-parse paths depend on the current path separator which is held in a static
-field. This path separator is part of the serialized state of a file so that
-file name can be adjusted when read.
-
-The serialized state of a `File` object is defined as the serializable fields
-and the sequence of data values for the file. In this case, there is one of
-each.
-
-```
-Serializable Fields:
- String path; // path name with embedded separators
-Serializable Data:
- char // path name separator for path name
-```
-
-An alternate implementation might be defined as follows:
-
-```
-class File implements java.io.Serializable {
- ...
- private String[] pathcomponents;
- // Define serializable fields with the ObjectStreamClass
-
- /**
- * @serialField path String
- * Path components separated by separator.
- */
-
- private static final ObjectStreamField[] serialPersistentFields
- = { new ObjectStreamField("path", String.class) };
- ...
- /**
- * @serialData Default fields followed by separator character.
- */
-
- private void writeObject(ObjectOutputStream s)
- throws IOException
- {
- ObjectOutputStream.PutField fields = s.putFields();
- StringBuffer str = new StringBuffer();
- for(int i = 0; i < pathcomponents; i++) {
- str.append(separator);

-title: 'Java Object Serialization Specification: B - Exceptions In Object Serialization'
----
-
--------------------------------------------------------------------------------
-
-All exceptions thrown by serialization classes are subclasses of
-`ObjectStreamException` which is a subclass of `IOException`.
-
-### `ObjectStreamException`
-
-Superclass of all serialization exceptions.
-
-### `InvalidClassException`
-
-Thrown when a class cannot be used to restore objects for any of these reasons:
-
-- The class does not match the serial version of the class in the stream.
-- The class contains fields with invalid primitive data types.
-- The `Externalizable` class does not have a public no-arg constructor.
-- The `Serializable` class can not access the no-arg constructor of its
- closest non-Serializable superclass.
-
-### `NotSerializableException`
-
-Thrown by a `readObject` or `writeObject` method to terminate serialization or
-deserialization.
-
-### `StreamCorruptedException`
-
-Thrown:
-
-- If the stream header is invalid.
-- If control information not found.
-- If control information is invalid.
-- JDK 1.1.5 or less attempts to call `readExternal` on a `PROTOCOL_VERSION_2`
- stream.
-
-### `NotActiveException`
-
-Thrown if `writeObject` state is invalid within the following
-`ObjectOutputStream` methods:
-
-- `defaultWriteObject`
-- `putFields`
-- `writeFields`
-
-Thrown if `readObject` state is invalid within the following
-`ObjectInputStream` methods:
-
-- `defaultReadObject`
-- `readFields`
-- `registerValidation`
-
-### `InvalidObjectException`
-
-Thrown when a restored object cannot be made valid.
-
-### `OptionalDataException`
-
-Thrown by `readObject` when there is primitive data in the stream and an object
-is expected. The length field of the exception indicates the number of bytes
-that are available in the current block.
-
-### `WriteAbortedException`
-
-Thrown when reading a stream terminated by an exception that occurred while the
-stream was being written.

-## 3.1 The ObjectInputStream Class
-
-Class `ObjectInputStream` implements object deserialization. It maintains the
-state of the stream including the set of objects already deserialized. Its
-methods allow primitive types and objects to be read from a stream written by
-`ObjectOutputStream`. It manages restoration of the object and the objects that
-it refers to from the stream.

-
-The single-argument `ObjectInputStream` constructor requires an `InputStream`.
-The constructor calls `readStreamHeader` to read and verifies the header and
-version written by the corresponding `ObjectOutputStream.writeStreamHeader`
-method. If a security manager is installed, this constructor checks for the
-`"enableSubclassImplementation"` `SerializablePermission` when invoked directly
-or indirectly by the constructor of a subclass which overrides the `readFields`
-and/or `readUnshared` methods.
-
-**Note:** The `ObjectInputStream` constructor blocks until it completes reading
-the serialization stream header. Code which waits for an `ObjectInputStream` to
-be constructed before creating the corresponding `ObjectOutputStream` for that
-stream will deadlock, since the `ObjectInputStream` constructor will block
-until a header is written to the stream, and the header will not be written to
-the stream until the `ObjectOutputStream` constructor executes. This problem
-can be resolved by creating the `ObjectOutputStream` before the
-`ObjectInputStream`, or otherwise removing the timing dependency between
-completion of `ObjectInputStream` construction and the creation of the
-`ObjectOutputStream`.
-
-The `readObject` method is used to deserialize an object from the stream. It
-reads from the stream to reconstruct an object.
-
-1. If the `ObjectInputStream` subclass is overriding the implementation, call
- the `readObjectOverride` method and return. Reimplementation is described
- at the end of this section.
-
-2. If a block data record occurs in the stream, throw a `BlockDataException`
- with the number of available bytes.
-
-3. If the object in the stream is null, return null.
-
-4. If the object in the stream is a handle to a previous object, return the
- object.
-
-5. If the object in the stream is a `Class`, read its `ObjectStreamClass`
- descriptor, add it and its handle to the set of known objects, and return
- the corresponding `Class` object.
-
-6. If the object in the stream is an `ObjectStreamClass`, read in its data
- according to the formats described in [Section 4.3, "Serialized
- Form"](class.html#serialized-form). Add it and its handle to the set of
- known objects. In versions 1.3 and later of the Java 2 SDK, Standard
- Edition, the `readClassDescriptor` method is called to read in the
- `ObjectStreamClass` if it represents a class that is not a dynamic proxy
- class, as indicated in the stream data. If the class descriptor represents
- a dynamic proxy class, call the `resolveProxyClass` method on the stream to
- get the local class for the descriptor; otherwise, call the `resolveClass`
- method on the stream to get the local class. If the class cannot be
- resolved, throw a ClassNotFoundException. Return the resulting
- `ObjectStreamClass` object.
-
-7. If the object in the stream is a `String`, read its length information
- followed by the contents of the string encoded in modified UTF-8. For
- details, refer to [Section 6.2, "Stream
- Elements"](protocol.html#stream-elements). Add the `String` and its handle
- to the set of known objects, and proceed to Step 12.
-
-8. If the object in the stream is an array, read its `ObjectStreamClass` and
- the length of the array. Allocate the array, and add it and its handle in
- the set of known objects. Read each element using the appropriate method
- for its type and assign it to the array. Proceed to Step 12.
-
-9. If the object in the stream is an enum constant, read its
- `ObjectStreamClass` and the enum constant name. If the `ObjectStreamClass`
- represents a class that is not an enum type, an `InvalidClassException` is
- thrown. Obtain a reference to the enum constant by calling the
- `java.lang.Enum.valueOf` method, passing the enum type bound to the
- received `ObjectStreamClass` along with the received name as arguments. If
- the `valueOf` method throws an `IllegalArgumentException`, an
- `InvalidObjectException` is thrown with the `IllegalArgumentException` as
- its cause. Add the enum constant and its handle in the set of known
- objects, and proceed to Step 12.
-
-10. For all other objects, the `ObjectStreamClass` of the object is read from
- the stream. The local class for that `ObjectStreamClass` is retrieved. The
- class must be serializable or externalizable, and must not be an enum type.
- If the class does not satisfy these criteria, an `InvalidClassException` is
- thrown.
-
-11. An instance of the class is allocated. The instance and its handle are
- added to the set of known objects. The contents restored appropriately:
-
- a. For serializable objects, the no-arg constructor for the first
- non-serializable supertype is run. For serializable classes, the fields
- are initialized to the default value appropriate for its type. Then the
- fields of each class are restored by calling class-specific
- `readObject` methods, or if these are not defined, by calling the
- `defaultReadObject` method. Note that field initializers and
- constructors are not executed for serializable classes during
- deserialization. In the normal case, the version of the class that
- wrote the stream will be the same as the class reading the stream. In
- this case, all of the supertypes of the object in the stream will match
- the supertypes in the currently-loaded class. If the version of the
- class that wrote the stream had different supertypes than the loaded
- class, the `ObjectInputStream` must be more careful about restoring or
- initializing the state of the differing classes. It must step through
- the classes, matching the available data in the stream with the classes
- of the object being restored. Data for classes that occur in the
- stream, but do not occur in the object, is discarded. For classes that
- occur in the object, but not in the stream, the class fields are set to
- default values by default serialization.
-
- b. For externalizable objects, the no-arg constructor for the class is run
- and then the `readExternal` method is called to restore the contents of
- the object.
-
-12. Process potential substitutions by the class of the object and/or by a
- subclass of `ObjectInputStream`:
-
- a. If the class of the object is not an enum type and defines the
- appropriate `readResolve` method, the method is called to allow the
- object to replace itself.
-
- b. Then if previously enabled by `enableResolveObject,` the
- `resolveObject` method is called to allow subclasses of the stream to
- examine and replace the object. If the previous step did replace the
- original object, the `resolveObject` method is called with the
- replacement object. If a replacement took place, the table of known
- objects is updated so the replacement object is associated with the
- handle. The replacement object is then returned from `readObject`.
-
-All of the methods for reading primitives types only consume bytes from the
-block data records in the stream. If a read for primitive data occurs when the
-next item in the stream is an object, the read methods return *-1* or the
-`EOFException` as appropriate. The value of a primitive type is read by a
-`DataInputStream` from the block data record.
-
-The exceptions thrown reflect errors during the traversal or exceptions that
-occur on the underlying stream. If any exception is thrown, the underlying
-stream is left in an unknown and unusable state.
-
-When the reset token occurs in the stream, all of the state of the stream is
-discarded. The set of known objects is cleared.
-
-When the exception token occurs in the stream, the exception is read and a new
-`WriteAbortedException` is thrown with the terminating exception as an
-argument. The stream context is reset as described earlier.
-
-The `readUnshared` method is used to read "unshared" objects from the stream.
-This method is identical to `readObject`, except that it prevents subsequent
-calls to `readObject` and `readUnshared` from returning additional references
-to the deserialized instance returned by the original call to `readUnshared`.
-Specifically:
-
-- If `readUnshared` is called to deserialize a back-reference (the stream
- representation of an object which has been written previously to the
- stream), an `ObjectStreamException` will be thrown.
-
-- If `readUnshared` returns successfully, then any subsequent attempts to
- deserialize back-references to the stream handle deserialized by
- `readUnshared` will cause an `ObjectStreamException` to be thrown.
-
-Deserializing an object via `readUnshared` invalidates the stream handle
-associated with the returned object. Note that this in itself does not always
-guarantee that the reference returned by `readUnshared` is unique; the
-deserialized object may define a `readResolve` method which returns an object
-visible to other parties, or `readUnshared` may return a `Class` object or enum
-constant obtainable elsewhere in the stream or through external means. If the
-deserialized object defines a `readResolve` method and the invocation of that
-method returns an array, then `readUnshared` returns a shallow clone of that
-array; this guarantees that the returned array object is unique and cannot be
-obtained a second time from an invocation of `readObject` or `readUnshared` on
-the `ObjectInputStream`, even if the underlying data stream has been
-manipulated.
-
-The `defaultReadObject` method is used to read the fields and object from the
-stream. It uses the class descriptor in the stream to read the fields in the
-canonical order by name and type from the stream. The values are assigned to
-the matching fields by name in the current class. Details of the versioning
-mechanism can be found in [Section 5.5, "Compatible Java Type
-Evolution"](version.html#compatible-java-type-evolution). Any field of the
-object that does not appear in the stream is set to its default value. Values
-that appear in the stream, but not in the object, are discarded. This occurs
-primarily when a later version of a class has written additional fields that do
-not occur in the earlier version. This method may only be called from the
-`readObject` method while restoring the fields of a class. When called at any
-other time, the `NotActiveException` is thrown.
-
-The `readFields` method reads the values of the serializable fields from the
-stream and makes them available via the `GetField` class. The `readFields`
-method is only callable from within the `readObject` method of a serializable
-class. It cannot be called more than once or if `defaultReadObject` has been
-called. The `GetFields` object uses the current object's `ObjectStreamClass` to
-verify the fields that can be retrieved for this class. The `GetFields` object
-returned by `readFields` is only valid during this call to the classes
-`readObject` method. The fields may be retrieved in any order. Additional data
-may only be read directly from stream after `readFields` has been called.
-
-The `registerValidation` method can be called to request a callback when the
-entire graph has been restored but before the object is returned to the
-original caller of `readObject`. The order of validate callbacks can be
-controlled using the priority. Callbacks registered with higher values are
-called before those with lower values. The object to be validated must support
-the `ObjectInputValidation` interface and implement the `validateObject`
-method. It is only correct to register validations during a call to a class's
-`readObject` method. Otherwise, a `NotActiveException` is thrown. If the
-callback object supplied to `registerValidation` is null, an
-`InvalidObjectException` is thrown.
-
-Starting with the Java SDK, Standard Edition, v1.3, the `readClassDescriptor`
-method is used to read in all `ObjectStreamClass` objects.
-`readClassDescriptor` is called when the `ObjectInputStream` expects a class
-descriptor as the next item in the serialization stream. Subclasses of
-`ObjectInputStream` may override this method to read in class descriptors that
-have been written in non-standard formats (by subclasses of
-`ObjectOutputStream` which have overridden the `writeClassDescriptor` method).
-By default, this method reads class descriptors according to the format
-described in [Section 6.4, "Grammar for the Stream
-Format"](protocol.html#grammar-for-the-stream-format).
-
-The `resolveClass` method is called while a class is being deserialized, and
-after the class descriptor has been read. Subclasses may extend this method to
-read other information about the class written by the corresponding subclass of
-`ObjectOutputStream`. The method must find and return the class with the given
-name and `serialVersionUID`. The default implementation locates the class by
-calling the class loader of the closest caller of `readObject` that has a class
-loader. If the class cannot be found `ClassNotFoundException` should be thrown.
-Prior to JDK 1.1.6, the `resolveClass` method was required to return the same
-fully qualified class name as the class name in the stream. In order to
-accommodate package renaming across releases, `method` `resolveClass` only
-needs to return a class with the same base class name and `SerialVersionUID` in
-JDK 1.1.6 and later versions.
-
-The `resolveObject` method is used by trusted subclasses to monitor or
-substitute one object for another during deserialization. Resolving objects
-must be enabled explicitly by calling `enableResolveObject` before calling
-`readObject` for the first object to be resolved. Once enabled, `resolveObject`
-is called once for each serializable object just prior to the first time it is
-being returned from `readObject`. Note that the `resolveObject` method is not
-called for objects of the specially handled classes, `Class`,
-`ObjectStreamClass`, `String`, and arrays. A subclass's implementation of
-`resolveObject` may return a substitute object that will be assigned or
-returned instead of the original. The object returned must be of a type that is
-consistent and assignable to every reference of the original object or else a
-`ClassCastException` will be thrown. All assignments are type-checked. All
-references in the stream to the original object will be replaced by references
-to the substitute object.
-
-The `enableResolveObject` method is called by trusted subclasses of
-`ObjectOutputStream` to enable the monitoring or substitution of one object for
-another during deserialization. Replacing objects is disabled until
-`enableResolveObject` is called with a `true` value. It may thereafter be
-disabled by setting it to `false`. The previous setting is returned. The
-`enableResolveObject` method checks if the stream has permission to request
-substitution during serialization. To ensure that the private state of objects
-is not unintentionally exposed, only trusted streams may use `resolveObject`.
-Trusted classes are those classes with a class loader equal to null or belong
-to a security protection domain that provides permission to enable
-substitution.
-
-If the subclass of `ObjectInputStream` is not considered part of the system
-domain, a line has to be added to the security policy file to provide to a
-subclass of `ObjectInputStream` permission to call `enableResolveObject`. The
-`SerializablePermission` to add is `"enableSubstitution"`.
-`AccessControlException` is thrown if the protection domain of the subclass of
-`ObjectStreamClass` does not have permission to `"enableSubstitution"` by
-calling `enableResolveObject`. See the document Java Security Architecture (JDK
-1.2) for additional information about the security model.
-
-The `readStreamHeader` method reads and verifies the magic number and version
-of the stream. If they do not match, the `StreamCorruptedMismatch` is thrown.
-
-To override the implementation of deserialization, a subclass of
-`ObjectInputStream` should call the protected no-arg `ObjectInputStream`,
-constructor. There is a security check within the no-arg constructor for
-`SerializablePermission "enableSubclassImplementation"` to ensure that only
-trusted classes are allowed to override the default implementation. This
-constructor does not allocate any private data for `ObjectInputStream` and sets
-a flag that indicates that the final `readObject` method should invoke the
-`readObjectOverride` method and return. All other `ObjectInputStream` methods
-are not final and can be directly overridden by the subclass.
-
-## 3.2 The ObjectInputStream.GetField Class
-
-The class `ObjectInputStream.GetField` provides the API for getting the values
-of serializable fields. The protocol of the stream is the same as used by
-`defaultReadObject.` Using `readFields` to access the serializable fields does
-not change the format of the stream. It only provides an alternate API to
-access the values which does not require the class to have the corresponding
-non-transient and non-static fields for each named serializable field. The
-serializable fields are those declared using `serialPersistentFields` or if it
-is not declared the non-transient and non-static fields of the object. When the
-stream is read the available serializable fields are those written to the
-stream when the object was serialized. If the class that wrote the stream is a
-different version not all fields will correspond to the serializable fields of
-the current class. The available fields can be retrieved from the
-`ObjectStreamClass` of the `GetField` object.
-
-The `getObjectStreamClass` method returns an `ObjectStreamClass` object
-representing the class in the stream. It contains the list of serializable
-fields.
-
-The `defaulted` method returns *true* if the field is not present in the
-stream. An `IllegalArgumentException` is thrown if the requested field is not a
-serializable field of the current class.
-
-Each `get` method returns the specified serializable field from the stream. I/O
-exceptions will be thrown if the underlying stream throws an exception. An
-`IllegalArgumentException` is thrown if the name or type does not match the
-name and type of an field serializable field of the current class. The default
-value is returned if the stream does not contain an explicit value for the
-field.
-
-## 3.3 The ObjectInputValidation Interface
-
-This interface allows an object to be called when a complete graph of objects
-has been deserialized. If the object cannot be made valid, it should throw the
-`ObjectInvalidException`. Any exception that occurs during a call to
-`validateObject` will terminate the validation process, and the
-`InvalidObjectException` will be thrown.
-
-```
-package java.io;
-
-public interface ObjectInputValidation
-{
- public void validateObject()
- throws InvalidObjectException;
-}
-```
-
-## 3.4 The readObject Method
-
-For serializable objects, the `readObject` method allows a class to control the
-deserialization of its own fields. Here is its signature:
-
-```
-private void readObject(ObjectInputStream stream)
- throws IOException, ClassNotFoundException;
-```
-
-Each subclass of a serializable object may define its own `readObject` method.
-If a class does not implement the method, the default serialization provided by
-`defaultReadObject` will be used. When implemented, the class is only
-responsible for restoring its own fields, not those of its supertypes or
-subtypes.
-
-The `readObject` method of the class, if implemented, is responsible for
-restoring the state of the class. The values of every field of the object
-whether transient or not, static or not are set to the default value for the
-fields type. Either `ObjectInputStream`'s `defaultReadObject` or `readFields`
-method must be called once (and only once) before reading any optional data
-written by the corresponding `writeObject` method; even if no optional data is
-read, `defaultReadObject` or `readFields` must still be invoked once. If the
-`readObject` method of the class attempts to read more data than is present in
-the optional part of the stream for this class, the stream will return `-1` for
-bytewise reads, throw an `EOFException` for primitive data reads (e.g.,
-`readInt`, `readFloat`), or throw an `OptionalDataException` with the `eof`
-field set to `true` for object reads.
-
-The responsibility for the format, structure, and versioning of the optional
-data lies completely with the class. The `@serialData` javadoc tag within the
-javadoc comment for the `readObject` method should be used to document the
-format and structure of the optional data.
-
-If the class being restored is not present in the stream being read, then its
-`readObjectNoData` method, if defined, is invoked (instead of `readObject`);
-otherwise, its fields are initialized to the appropriate default values. For
-further detail, see [Section 3.5, "The readObjectNoData
-Method"](#the-readobjectnodata-method).
-
-Reading an object from the `ObjectInputStream` is analogous to creating a new
-object. Just as a new object's constructors are invoked in the order from the
-superclass to the subclass, an object being read from a stream is deserialized
-from superclass to subclass. The `readObject` or `readObjectNoData` method is
-called instead of the constructor for each `Serializable` subclass during
-deserialization.
-
-One last similarity between a constructor and a `readObject` method is that
-both provide the opportunity to invoke a method on an object that is not fully
-constructed. Any overridable (neither private, static nor final) method called
-while an object is being constructed can potentially be overridden by a
-subclass. Methods called during the construction phase of an object are
-resolved by the actual type of the object, not the type currently being
-initialized by either its constructor or `readObject`/`readObjectNoData`
-method. Therefore, calling an overridable method from within a `readObject` or
-`readObjectNoData` method may result in the unintentional invocation of a
-subclass method before the superclass has been fully initialized.
-
-## 3.5 The readObjectNoData Method
-
-For serializable objects, the `readObjectNoData` method allows a class to
-control the initialization of its own fields in the event that a subclass
-instance is deserialized and the serialization stream does not list the class
-in question as a superclass of the deserialized object. This may occur in cases
-where the receiving party uses a different version of the deserialized
-instance's class than the sending party, and the receiver's version extends
-classes that are not extended by the sender's version. This may also occur if
-the serialization stream has been tampered; hence, `readObjectNoData` is useful
-for initializing deserialized objects properly despite a "hostile" or
-incomplete source stream.
-
-```
-private void readObjectNoData() throws ObjectStreamException;
-```
-
-Each serializable class may define its own `readObjectNoData` method. If a
-serializable class does not define a `readObjectNoData` method, then in the
-circumstances listed above the fields of the class will be initialized to their
-default values (as listed in The Java Language Specification); this behavior is
-consistent with that of `ObjectInputStream` prior to version 1.4 of the Java 2
-SDK, Standard Edition, when support for `readObjectNoData` methods was
-introduced. If a serializable class does define a `readObjectNoData` method and
-the aforementioned conditions arise, then `readObjectNoData` will be invoked at
-the point during deserialization when a class-defined `readObject` method would
-otherwise be called had the class in question been listed by the stream as a
-superclass of the instance being deserialized.
-
-## 3.6 The readExternal Method
-
-Objects implementing `java.io.Externalizable` must implement the `readExternal`
-method to restore the entire state of the object. It must coordinate with its
-superclasses to restore their state. All of the methods of `ObjectInput` are
-available to restore the object's primitive typed fields and object fields.
-
-```
-public void readExternal(ObjectInput stream)
- throws IOException;
-```
-
-**Note:** The `readExternal` method is public, and it raises the risk of a
-client being able to overwrite an existing object from a stream. The class may
-add its own checks to insure that this is only called when appropriate.
-
-A new stream protocol version has been introduced in JDK 1.2 to correct a
-problem with `Externalizable` objects. The old definition of `Externalizable`
-objects required the local virtual machine to find a `readExternal` method to
-be able to properly read an `Externalizable` object from the stream. The new
-format adds enough information to the stream protocol so serialization can skip
-an `Externalizable` object when the local `readExternal` method is not
-available. Due to class evolution rules, serialization must be able to skip an
-`Externalizable` object in the input stream if there is not a mapping for the
-object using the local classes.
-
-An additional benefit of the new `Externalizable` stream format is that
-`ObjectInputStream` can detect attempts to read more External data than is
-available, and can also skip by any data that is left unconsumed by a
-`readExternal` method. The behavior of `ObjectInputStream` in response to a
-read past the end of External data is the same as the behavior when a
-class-defined `readObject` method attempts to read past the end of its optional
-data: bytewise reads will return `-1`, primitive reads will throw
-`EOFException`s, and object reads will throw `OptionalDataException`s with the
-`eof` field set to `true`.
-
-Due to the format change, JDK 1.1.6 and earlier releases are not able to read
-the new format. `StreamCorruptedException` is thrown when JDK 1.1.6 or earlier
-attempts to read an `Externalizable` object from a stream written in
-`PROTOCOL_VERSION_2`. Compatibility issues are discussed in more detail in
-[Section 6.3, "Stream Protocol
-Versions"](protocol.html#stream-protocol-versions).
-
-## 3.7 The readResolve Method
-
-For Serializable and Externalizable classes, the `readResolve` method allows a
-class to replace/resolve the object read from the stream before it is returned
-to the caller. By implementing the `readResolve` method, a class can directly
-control the types and instances of its own instances being deserialized. The
-method is defined as follows:
-
-```
-ANY-ACCESS-MODIFIER Object readResolve()
- throws ObjectStreamException;
-```
-
-The `readResolve` method is called when `ObjectInputStream` has read an object
-from the stream and is preparing to return it to the caller.
-`ObjectInputStream` checks whether the class of the object defines the
-`readResolve` method. If the method is defined, the `readResolve` method is
-called to allow the object in the stream to designate the object to be
-returned. The object returned should be of a type that is compatible with all
-uses. If it is not compatible, a `ClassCastException` will be thrown when the
-type mismatch is discovered.
-
-For example, a `Symbol` class could be created for which only a single instance
-of each symbol binding existed within a virtual machine. The `readResolve`
-method would be implemented to determine if that symbol was already defined and
-substitute the preexisting equivalent `Symbol` object to maintain the identity
-constraint. In this way the uniqueness of `Symbol` objects can be maintained
-across serialization.
-
-**Note:** The `readResolve` method is not invoked on the object until the
-object is fully constructed, so any references to this object in its object
-graph will not be updated to the new object nominated by `readResolve`.
-However, during the serialization of an object with the `writeReplace` method,
-all references to the original object in the replacement object's object graph
-are replaced with references to the replacement object. Therefore in cases
-where an object being serialized nominates a replacement object whose object
-graph has a reference to the original object, deserialization will result in an
-incorrect graph of objects. Furthermore, if the reference types of the object
-being read (nominated by `writeReplace`) and the original object are not
-compatible, the construction of the object graph will raise a
-`ClassCastException`.

-
-The single-argument `ObjectOutputStream` constructor creates an
-`ObjectOutputStream` that serializes objects to the given `OutputStream`. The
-constructor calls `writeStreamHeader` to write a magic number and version to
-the stream that will be read and verified by a corresponding call to
-`readStreamHeader` in the single-argument `ObjectInputStream` constructor. If a
-security manager is installed, this constructor checks for the
-`"enableSubclassImplementation"` `SerializablePermission` when invoked directly
-or indirectly by the constructor of a subclass which overrides the `putFields`
-and/or `writeUnshared` methods.
-
-The `writeObject` method is used to serialize an object to the stream. An
-object is serialized as follows:
-
-1. If a subclass is overriding the implementation, call the
- `writeObjectOverride` method and return. Overriding the implementation is
- described at the end of this section.
-
-2. If there is data in the block-data buffer, the data is written to the
- stream and the buffer is reset.
-
-3. If the object is null, null is put in the stream and `writeObject` returns.
-
-4. If the object has been previously replaced, as described in Step 8, write
- the handle of the replacement to the stream and `writeObject` returns.
-
-5. If the object has already been written to the stream, its handle is written
- to the stream and `writeObject` returns.
-
-6. If the object is a `Class`, the corresponding `ObjectStreamClass` is
- written to the stream, a handle is assigned for the class, and
- `writeObject` returns.
-
-7. If the object is an `ObjectStreamClass`, a handle is assigned to the
- object, after which it is written to the stream using one of the class
- descriptor formats described in [Section 4.3, "Serialized
- Form"](class.html#serialized-form). In versions 1.3 and later of the Java 2
- SDK, Standard Edition, the `writeClassDescriptor` method is called to
- output the `ObjectStreamClass` if it represents a class that is not a
- dynamic proxy class, as determined by passing the associated `Class` object
- to the `isProxyClass` method of `java.lang.reflect.Proxy`. Afterwards, an
- annotation for the represented class is written: if the class is a dynamic
- proxy class, then the `annotateProxyClass` method is called; otherwise, the
- `annotateClass` method is called. The `writeObject` method then returns.
-
-8. Process potential substitutions by the class of the object and/or by a
- subclass of `ObjectInputStream`.
-
- a. If the class of an object is not an enum type and defines the
- appropriate `writeReplace` method, the method is called. Optionally, it
- can return a substitute object to be serialized.
-
- b. Then, if enabled by calling the `enableReplaceObject` method, the
- `replaceObject` method is called to allow subclasses of
- `ObjectOutputStream` to substitute for the object being serialized. If
- the original object was replaced in the previous step, the
- `replaceObject` method is called with the replacement object.
-
- If the original object was replaced by either one or both steps above, the
- mapping from the original object to the replacement is recorded for later
- use in Step 4. Then, Steps 3 through 7 are repeated on the new object.
-
- If the replacement object is not one of the types covered by Steps 3
- through 7, processing resumes using the replacement object at Step 10.
-
-9. <a id="java-lang-string-encoding"></a>
- If the object is a `java.lang.String,` the string is written as length
- information followed by the contents of the string encoded in modified
- UTF-8. For details, refer to [Section 6.2, "Stream
- Elements"](protocol.html#stream-elements). A handle is assigned to the
- string, and `writeObject` returns.
-
-10. If the object is an array, `writeObject` is called recursively to write the
- `ObjectStreamClass` of the array. The handle for the array is assigned. It
- is followed by the length of the array. Each element of the array is then
- written to the stream, after which `writeObject` returns.
-
-11. If the object is an enum constant, the `ObjectStreamClass` for the enum
- type of the constant is written by recursively calling `writeObject`. It
- will appear in the stream only the first time it is referenced. A handle is
- assigned for the enum constant. Next, the value returned by the `name`
- method of the enum constant is written as a `String` object, as described
- in step 9. Note that if the same name string has appeared previously in the
- stream, a back reference to it will be written. The `writeObject` method
- then returns.
-
-12. For regular objects, the `ObjectStreamClass` for the class of the object is
- written by recursively calling `writeObject`. It will appear in the stream
- only the first time it is referenced. A handle is assigned for the object.
-
-13. The contents of the object are written to the stream.
-
- a. If the object is serializable, the highest serializable class is
- located. For that class, and each derived class, that class's fields
- are written. If the class does not have a `writeObject` method, the
- `defaultWriteObject` method is called to write the serializable fields
- to the stream. If the class does have a `writeObject` method, it is
- called. It may call `defaultWriteObject` or `putFields` and
- `writeFields` to save the state of the object, and then it can write
- other information to the stream.
-
- b. If the object is externalizable, the `writeExternal` method of the
- object is called.
-
- c. If the object is neither serializable or externalizable, the
- `NotSerializableException` is thrown.
-
-Exceptions may occur during the traversal or may occur in the underlying
-stream. For any subclass of `IOException`, the exception is written to the
-stream using the exception protocol and the stream state is discarded. If a
-second `IOException` is thrown while attempting to write the first exception
-into the stream, the stream is left in an unknown state and
-`StreamCorruptedException` is thrown from `writeObject`. For other exceptions,
-the stream is aborted and left in an unknown and unusable state.
-
-The `writeUnshared` method writes an "unshared" object to the
-`ObjectOutputStream`. This method is identical to `writeObject`, except that it
-always writes the given object as a new, unique object in the stream (as
-opposed to a back-reference pointing to a previously serialized instance).
-Specifically:
-
-- An object written via `writeUnshared` is always serialized in the same
- manner as a newly appearing object (an object that has not been written to
- the stream yet), regardless of whether or not the object has been written
- previously.
-
-- If `writeObject` is used to write an object that has been previously
- written with `writeUnshared`, the previous `writeUnshared` operation is
- treated as if it were a write of a separate object. In other words,
- `ObjectOutputStream` will never generate back-references to object data
- written by calls to `writeUnshared`.
-
-While writing an object via `writeUnshared` does not in itself guarantee a
-unique reference to the object when it is deserialized, it allows a single
-object to be defined multiple times in a stream, so that multiple calls to the
-`ObjectInputStream.readUnshared` method (see [Section 3.1, "The
-ObjectInputStream Class"](input.html#the-objectinputstream-class)) by the
-receiver will not conflict. Note that the rules described above only apply to
-the base-level object written with `writeUnshared`, and not to any transitively
-referenced sub-objects in the object graph to be serialized.
-
-The `defaultWriteObject` method implements the default serialization mechanism
-for the current class. This method may be called only from a class's
-`writeObject` method. The method writes all of the serializable fields of the
-current class to the stream. If called from outside the `writeObject` method,
-the `NotActiveException` is thrown.
-
-The `putFields` method returns a `PutField` object the caller uses to set the
-values of the serializable fields in the stream. The fields may be set in any
-order. After all of the fields have been set, `writeFields` must be called to
-write the field values in the canonical order to the stream. If a field is not
-set, the default value appropriate for its type will be written to the stream.
-This method may only be called from within the `writeObject` method of a
-serializable class. It may not be called more than once or if
-`defaultWriteObject` has been called. Only after `writeFields` has been called
-can other data be written to the stream.
-
-The `reset` method resets the stream state to be the same as if it had just
-been constructed. `Reset` will discard the state of any objects already written
-to the stream. The current point in the stream is marked as reset, so the
-corresponding `ObjectInputStream` will reset at the same point. Objects
-previously written to the stream will not be remembered as already having been
-written to the stream. They will be written to the stream again. This is useful
-when the contents of an object or objects must be sent again. `Reset` may not
-be called while objects are being serialized. If called inappropriately, an
-`IOException` is thrown.
-
-Starting with the Java 2 SDK, Standard Edition, v1.3, the
-`writeClassDescriptor` method is called when an `ObjectStreamClass` needs to be
-serialized. `writeClassDescriptor` is responsible for writing a representation
-of the `ObjectStreamClass` to the serialization stream. Subclasses may override
-this method to customize the way in which class descriptors are written to the
-serialization stream. If this method is overridden, then the corresponding
-`readClassDescriptor` method in `ObjectInputStream` should also be overridden
-to reconstitute the class descriptor from its custom stream representation. By
-default, `writeClassDescriptor` writes class descriptors according to the
-format specified in [Section 6.4, "Grammar for the Stream
-Format"](protocol.html#grammar-for-the-stream-format). Note that this method
-will only be called if the `ObjectOutputStream` is not using the old
-serialization stream format (see [Section 6.3, "Stream Protocol
-Versions"](protocol.html#stream-protocol-versions)). If the serialization
-stream is using the old format (`ObjectStreamConstants.PROTOCOL_VERSION_1`),
-the class descriptor will be written internally in a manner that cannot be
-overridden or customized.
-
-The `annotateClass` method is called while a `Class` is being serialized, and
-after the class descriptor has been written to the stream. Subclasses may
-extend this method and write other information to the stream about the class.
-This information must be read by the `resolveClass` method in a corresponding
-`ObjectInputStream` subclass.
-
-An `ObjectOutputStream` subclass can implement the `replaceObject` method to
-monitor or replace objects during serialization. Replacing objects must be
-enabled explicitly by calling `enableReplaceObject` before calling
-`writeObject` with the first object to be replaced. Once enabled,
-`replaceObject` is called for each object just prior to serializing the object
-for the first time. Note that the `replaceObject` method is not called for
-objects of the specially handled classes, `Class` and `ObjectStreamClass`. An
-implementation of a subclass may return a substitute object that will be
-serialized instead of the original. The substitute object must be serializable.
-All references in the stream to the original object will be replaced by the
-substitute object.
-
-When objects are being replaced, the subclass must ensure that the substituted
-object is compatible with every field where the reference will be stored, or
-that a complementary substitution will be made during deserialization. Objects,
-whose type is not a subclass of the type of the field or array element, will
-later abort the deserialization by raising a `ClassCastException` and the
-reference will not be stored.
-
-The `enableReplaceObject` method can be called by trusted subclasses of
-`ObjectOutputStream` to enable the substitution of one object for another
-during serialization. Replacing objects is disabled until `enableReplaceObject`
-is called with a `true` value. It may thereafter be disabled by setting it to
-`false`. The previous setting is returned. The `enableReplaceObject` method
-checks that the stream requesting the replacement can be trusted. To ensure
-that the private state of objects is not unintentionally exposed, only trusted
-stream subclasses may use `replaceObject`. Trusted classes are those classes
-that belong to a security protection domain with permission to enable
-Serializable substitution.
-
-If the subclass of `ObjectOutputStream` is not considered part of the system
-domain, `SerializablePermission "enableSubstitution"` must be added to the
-security policy file. `AccessControlException` is thrown if the protection
-domain of the subclass of `ObjectInputStream` does not have permission to
-`"enableSubstitution"` by calling `enableReplaceObject`. See the document Java
-Security Architecture (JDK1.2) for additional information about the security
-model.
-
-The `writeStreamHeader` method writes the magic number and version to the
-stream. This information must be read by the `readStreamHeader` method of
-`ObjectInputStream`. Subclasses may need to implement this method to identify
-the stream's unique format.
-
-The `flush` method is used to empty any buffers being held by the stream and to
-forward the flush to the underlying stream. The `drain` method may be used by
-subclassers to empty only the `ObjectOutputStream`'s buffers without forcing
-the underlying stream to be flushed.
-
-All of the write methods for primitive types encode their values using a
-`DataOutputStream` to put them in the standard stream format. The bytes are
-buffered into block data records so they can be distinguished from the encoding
-of objects. This buffering allows primitive data to be skipped if necessary for
-class versioning. It also allows the stream to be parsed without invoking
-class-specific methods.
-
-To override the implementation of serialization, the subclass of
-`ObjectOutputStream` should call the protected no-arg `ObjectOutputStream`,
-constructor. There is a security check within the no-arg constructor for
-`SerializablePermission "enableSubclassImplementation"` to ensure that only
-trusted classes are allowed to override the default implementation. This
-constructor does not allocate any private data for `ObjectOutputStream` and
-sets a flag that indicates that the final `writeObject` method should invoke
-the `writeObjectOverride` method and return. All other `ObjectOutputStream`
-methods are not final and can be directly overridden by the subclass.
-
-## 2.2 The ObjectOutputStream.PutField Class
-
-Class `PutField` provides the API for setting values of the serializable fields
-for a class when the class does not use default serialization. Each method puts
-the specified named value into the stream. An `IllegalArgumentException` is
-thrown if `name` does not match the name of a serializable field for the class
-whose fields are being written, or if the type of the named field does not
-match the second parameter type of the specific `put` method invoked.
-
-## 2.3 The writeObject Method
-
-For serializable objects, the `writeObject` method allows a class to control
-the serialization of its own fields. Here is its signature:
-
-```
-private void writeObject(ObjectOutputStream stream)
- throws IOException;
-```
-
-Each subclass of a serializable object may define its own `writeObject` method.
-If a class does not implement the method, the default serialization provided by
-`defaultWriteObject` will be used. When implemented, the class is only
-responsible for writing its own fields, not those of its supertypes or
-subtypes.
-
-The class's `writeObject` method, if implemented, is responsible for saving the
-state of the class. Either `ObjectOutputStream`'s `defaultWriteObject` or
-`writeFields` method must be called once (and only once) before writing any
-optional data that will be needed by the corresponding `readObject` method to
-restore the state of the object; even if no optional data is written,
-`defaultWriteObject` or `writeFields` must still be invoked once. If
-`defaultWriteObject` or `writeFields` is not invoked once prior to the writing
-of optional data (if any), then the behavior of instance deserialization is
-undefined in cases where the `ObjectInputStream` cannot resolve the class which
-defined the `writeObject` method in question.
-
-The responsibility for the format, structure, and versioning of the optional
-data lies completely with the class.
-
-## 2.4 The writeExternal Method
-
-Objects implementing `java.io.Externalizable` must implement the
-`writeExternal` method to save the entire state of the object. It must
-coordinate with its superclasses to save their state. All of the methods of
-`ObjectOutput` are available to save the object's primitive typed fields and
-object fields.
-
-```
-public void writeExternal(ObjectOutput stream)
- throws IOException;
-```
-
-A new default format for writing Externalizable data has been introduced in JDK
-1.2. The new format specifies that primitive data will be written in block data
-mode by `writeExternal` methods. Additionally, a tag denoting the end of the
-External object is appended to the stream after the `writeExternal` method
-returns. The benefits of this format change are discussed in [Section 3.6, "The
-readExternal Method"](input.html#the-readexternal-method). Compatibility issues
-caused by this change are discussed in [Section 2.6, "The useProtocolVersion
-Method"](#the-useprotocolversion-method).
-
-## 2.5 The writeReplace Method
-
-For Serializable and Externalizable classes, the `writeReplace` method allows a
-class of an object to nominate its own replacement in the stream before the
-object is written. By implementing the `writeReplace` method, a class can
-directly control the types and instances of its own instances being serialized.
-
-The method is defined as follows:
-
-```
-ANY-ACCESS-MODIFIER Object writeReplace()
- throws ObjectStreamException;
-```
-
-The `writeReplace` method is called when `ObjectOutputStream` is preparing to
-write the object to the stream. The `ObjectOutputStream` checks whether the
-class defines the `writeReplace` method. If the method is defined, the
-`writeReplace` method is called to allow the object to designate its
-replacement in the stream. The object returned should be either of the same
-type as the object passed in or an object that when read and resolved will
-result in an object of a type that is compatible with all references to the
-object. If it is not, a `ClassCastException` will occur when the type mismatch
-is discovered.
-
-## 2.6 The useProtocolVersion Method
-
-Due to a stream protocol change that was not backwards compatible, a mechanism
-has been added to enable the current Virtual Machine to write a serialization
-stream that is readable by a previous release. Of course, the problems that are
-corrected by the new stream format will exist when using the backwards
-compatible protocol.
-
-Stream protocol versions are discussed in [Section 6.3, "Stream Protocol
-Versions"](protocol.html#stream-protocol-versions).

-- [Stream Protocol Versions](#stream-protocol-versions)
-- [Grammar for the Stream Format](#grammar-for-the-stream-format)
-- [Example](#example)
-
--------------------------------------------------------------------------------
-
-## 6.1 Overview
-
-The stream format satisfies the following design goals:
-
-- Is compact and is structured for efficient reading.
-- Allows skipping through the stream using only the knowledge of the
- structure and format of the stream. Does not require invoking any per class
- code.
-- Requires only stream access to the data.
-
-## 6.2 Stream Elements
-
-A basic structure is needed to represent objects in a stream. Each attribute of
-the object needs to be represented: its classes, its fields, and data written
-and later read by class-specific methods. The representation of objects in the
-stream can be described with a grammar. There are special representations for
-null objects, new objects, classes, arrays, strings, and back references to any
-object already in the stream. Each object written to the stream is assigned a
-handle that is used to refer back to the object. Handles are assigned
-sequentially starting from 0x7E0000. The handles restart at 0x7E0000 when the
-stream is reset.
-
-A class object is represented by the following:
-
-- Its `ObjectStreamClass` object.
-
-An `ObjectStreamClass` object for a Class that is not a dynamic proxy class is
-represented by the following:
-
-- The Stream Unique Identifier (SUID) of compatible classes.
-
-- A set of flags indicating various properties of the class, such as whether
- the class defines a `writeObject` method, and whether the class is
- serializable, externalizable, or an enum type
-
-- The number of serializable fields
-
-- The array of fields of the class that are serialized by the default
- mechanismFor arrays and object fields, the type of the field is included as
- a string which must be in "field descriptor" format (e.g.,
- "`Ljava/lang/Object;`") as specified in The Java Virtual Machine
- Specification.
-
-- Optional block-data records or objects written by the `annotateClass`
- method
-
-- The `ObjectStreamClass` of its supertype (null if the superclass is not
- serializable)
-
-An `ObjectStreamClass` object for a dynamic proxy class is represented by the
-following:
-
-- The number of interfaces that the dynamic proxy class implements
-
-- The names of all of the interfaces implemented by the dynamic proxy class,
- listed in the order that they are returned by invoking the `getInterfaces`
- method on the Class object.
-
-- Optional block-data records or objects written by the `annotateProxyClass`
- method.
-
-- The ObjectStreamClass of its supertype, `java.lang.reflect.Proxy`.
-
-The representation of `String` objects consists of length information followed
-by the contents of the string encoded in modified UTF-8. The modified UTF-8
-encoding is the same as used in the Java Virtual Machine and in the
-`java.io.DataInput` and `DataOutput` interfaces; it differs from standard UTF-8
-in the representation of supplementary characters and of the null character.
-The form of the length information depends on the length of the string in
-modified UTF-8 encoding. If the modified UTF-8 encoding of the given `String`
-is less than 65536 bytes in length, the length is written as 2 bytes
-representing an unsigned 16-bit integer. Starting with the Java 2 platform,
-Standard Edition, v1.3, if the length of the string in modified UTF-8 encoding
-is 65536 bytes or more, the length is written in 8 bytes representing a signed
-64-bit integer. The typecode preceding the `String` in the serialization stream
-indicates which format was used to write the `String`.
-
-Arrays are represented by the following:
-
-- Their `ObjectStreamClass` object.
-
-- The number of elements.
-
-- The sequence of values. The type of the values is implicit in the type of
- the array. for example the values of a byte array are of type byte.
-
-Enum constants are represented by the following:
-
-- The `ObjectStreamClass` object of the constant's base enum type.
-
-- The constant's name string.
-
-New objects in the stream are represented by the following:
-
-- The most derived class of the object.
-
-- Data for each serializable class of the object, with the highest superclass
- first. For each class the stream contains the following:
-
- - The serializable fields.See [Section 1.5, "Defining Serializable Fields
- for a
- Class"](serial-arch.html#defining-serializable-fields-for-a-class).
-
- - If the class has `writeObject`/`readObject` methods, there may be
- optional objects and/or block-data records of primitive types written
- by the `writeObject` method followed by an `endBlockData` code.
-
-All primitive data written by classes is buffered and wrapped in block-data
-records, regardless if the data is written to the stream within a `writeObject`
-method or written directly to the stream from outside a `writeObject` method.
-This data can only be read by the corresponding `readObject` methods or be read
-directly from the stream. Objects written by the `writeObject` method terminate
-any previous block-data record and are written either as regular objects or
-null or back references, as appropriate. The block-data records allow error
-recovery to discard any optional data. When called from within a class, the
-stream can discard any data or objects until the `endBlockData`.
-
-## 6.3 Stream Protocol Versions
-
-It was necessary to make a change to the serialization stream format in JDK 1.2
-that is not backwards compatible to all minor releases of JDK 1.1. To provide
-for cases where backwards compatibility is required, a capability has been
-added to indicate what `PROTOCOL_VERSION` to use when writing a serialization
-stream. The method `ObjectOutputStream.useProtocolVersion` takes as a parameter
-the protocol version to use to write the serialization stream.
-
-The Stream Protocol Versions are as follows:
-
-- `ObjectStreamConstants.PROTOCOL_VERSION_1`: Indicates the initial stream
- format.
-
-- `ObjectStreamConstants.PROTOCOL_VERSION_2`: Indicates the new external data
- format. Primitive data is written in block data mode and is terminated with
- `TC_ENDBLOCKDATA`.
-
- Block data boundaries have been standardized. Primitive data written in
- block data mode is normalized to not exceed 1024 byte chunks. The benefit
- of this change was to tighten the specification of serialized data format
- within the stream. This change is fully backward and forward compatible.
-
-JDK 1.2 defaults to writing `PROTOCOL_VERSION_2`.
-
-JDK 1.1 defaults to writing `PROTOCOL_VERSION_1`.
-
-JDK 1.1.7 and greater can read both versions.
-
-Releases prior to JDK 1.1.7 can only read `PROTOCOL_VERSION_1`.
-
-## 6.4 Grammar for the Stream Format
-
-The table below contains the grammar for the stream format. Nonterminal symbols
-are shown in italics. Terminal symbols in a *fixed width font*. Definitions of
-nonterminals are followed by a ":". The definition is followed by one or more
-alternatives, each on a separate line. The following table describes the
-notation:
-
- ------------- --------------------------------------------------------------
- **Notation** **Meaning**
- ------------- --------------------------------------------------------------
- (*datatype*) This token has the data type specified, such as byte.
-
- *token*\[n\] A predefined number of occurrences of the token, that is an
- array.
-
- *x0001* A literal value expressed in hexadecimal. The number of hex
- digits reflects the size of the value.
-
- <*xxx*> A value read from the stream used to indicate the length of an
- array.
- ------------- --------------------------------------------------------------
-
-Note that the symbol (utf) is used to designate a string written using 2-byte
-length information, and (long-utf) is used to designate a string written using
-8-byte length information. For details, refer to [Section 6.2, "Stream
-Elements"](#stream-elements).
-

-
-### 6.4.2 Terminal Symbols and Constants
-
-The following symbols in `java.io.ObjectStreamConstants` define the terminal
-and constant values expected in a stream.
-
-```
-final static short STREAM_MAGIC = (short)0xaced;
-final static short STREAM_VERSION = 5;
-final static byte TC_NULL = (byte)0x70;
-final static byte TC_REFERENCE = (byte)0x71;
-final static byte TC_CLASSDESC = (byte)0x72;
-final static byte TC_OBJECT = (byte)0x73;
-final static byte TC_STRING = (byte)0x74;
-final static byte TC_ARRAY = (byte)0x75;
-final static byte TC_CLASS = (byte)0x76;
-final static byte TC_BLOCKDATA = (byte)0x77;
-final static byte TC_ENDBLOCKDATA = (byte)0x78;
-final static byte TC_RESET = (byte)0x79;
-final static byte TC_BLOCKDATALONG = (byte)0x7A;
-final static byte TC_EXCEPTION = (byte)0x7B;
-final static byte TC_LONGSTRING = (byte) 0x7C;
-final static byte TC_PROXYCLASSDESC = (byte) 0x7D;
-final static byte TC_ENUM = (byte) 0x7E;
-final static int baseWireHandle = 0x7E0000;
-```
-
-The flag byte *classDescFlags* may include values of
-
-```
-final static byte SC_WRITE_METHOD = 0x01; //if SC_SERIALIZABLE
-final static byte SC_BLOCK_DATA = 0x08; //if SC_EXTERNALIZABLE
-final static byte SC_SERIALIZABLE = 0x02;
-final static byte SC_EXTERNALIZABLE = 0x04;
-final static byte SC_ENUM = 0x10;
-```
-
-The flag `SC_WRITE_METHOD` is set if the Serializable class writing the stream
-had a `writeObject` method that may have written additional data to the stream.
-In this case a `TC_ENDBLOCKDATA` marker is always expected to terminate the
-data for that class.
-
-The flag `SC_BLOCKDATA` is set if the `Externalizable` class is written into
-the stream using `STREAM_PROTOCOL_2`. By default, this is the protocol used to
-write `Externalizable` objects into the stream in JDK 1.2. JDK 1.1 writes
-`STREAM_PROTOCOL_1`.
-
-The flag `SC_SERIALIZABLE` is set if the class that wrote the stream extended
-`java.io.Serializable` but not `java.io.Externalizable`, the class reading the
-stream must also extend `java.io.Serializable` and the default serialization
-mechanism is to be used.
-
-The flag `SC_EXTERNALIZABLE` is set if the class that wrote the stream extended
-`java.io.Externalizable`, the class reading the data must also extend
-`Externalizable` and the data will be read using its `writeExternal` and
-`readExternal` methods.
-
-The flag `SC_ENUM` is set if the class that wrote the stream was an enum type.
-The receiver's corresponding class must also be an enum type. Data for
-constants of the enum type will be written and read as described in [Section
-1.12, "Serialization of Enum
-Constants"](serial-arch.html#serialization-of-enum-constants).
-
-#### Example
-
-Consider the case of an original class and two instances in a linked list:
-
-```
-class List implements java.io.Serializable {
- int value;
- List next;
- public static void main(String[] args) {
- try {
- List list1 = new List();
- List list2 = new List();
- list1.value = 17;
- list1.next = list2;
- list2.value = 19;
- list2.next = null;
-
- ByteArrayOutputStream o = new ByteArrayOutputStream();
- ObjectOutputStream out = new ObjectOutputStream(o);
- out.writeObject(list1);
- out.writeObject(list2);
- out.flush();
- ...
- } catch (Exception ex) {
- ex.printStackTrace();
- }
- }
-}
-```
-
-The resulting stream contains:
-
-```
- 00: ac ed 00 05 73 72 00 04 4c 69 73 74 69 c8 8a 15 >....sr..Listi...<

-## 1.1 Overview
-
-The ability to store and retrieve Java^TM^ objects is essential to building all
-but the most transient applications. The key to storing and retrieving objects
-in a serialized form is representing the state of objects sufficient to
-reconstruct the object(s). Objects to be saved in the stream may support either
-the `Serializable` or the `Externalizable` interface. For Java^TM^ objects, the
-serialized form must be able to identify and verify the Java^TM^ class from
-which the contents of the object were saved and to restore the contents to a
-new instance. For serializable objects, the stream includes sufficient
-information to restore the fields in the stream to a compatible version of the
-class. For Externalizable objects, the class is solely responsible for the
-external format of its contents.
-
-Objects to be stored and retrieved frequently refer to other objects. Those
-other objects must be stored and retrieved at the same time to maintain the
-relationships between the objects. When an object is stored, all of the objects
-that are reachable from that object are stored as well.
-
-The goals for serializing Java^TM^ objects are to:
-
-- Have a simple yet extensible mechanism.
-- Maintain the Java^TM^ object type and safety properties in the serialized
- form.
-- Be extensible to support marshaling and unmarshaling as needed for remote
- objects.
-- Be extensible to support simple persistence of Java^TM^ objects.
-- Require per class implementation only for customization.
-- Allow the object to define its external format.
-
-## 1.2 Writing to an Object Stream
-
-Writing objects and primitives to a stream is a straightforward process. For
-example:
-
-```
-// Serialize today's date to a file.
- FileOutputStream f = new FileOutputStream("tmp");
- ObjectOutput s = new ObjectOutputStream(f);
- s.writeObject("Today");
- s.writeObject(new Date());
- s.flush();
-```
-
-First an `OutputStream`, in this case a `FileOutputStream`, is needed to
-receive the bytes. Then an `ObjectOutputStream` is created that writes to the
-`FileOutputStream`. Next, the string "Today" and a Date object are written to
-the stream. More generally, objects are written with the `writeObject` method
-and primitives are written to the stream with the methods of `DataOutput`.
-
-The `writeObject` method (see [Section 2.3, "The writeObject
-Method"](output.html#the-writeobject-method)) serializes the specified object
-and traverses its references to other objects in the object graph recursively
-to create a complete serialized representation of the graph. Within a stream,
-the first reference to any object results in the object being serialized or
-externalized and the assignment of a handle for that object. Subsequent
-references to that object are encoded as the handle. Using object handles
-preserves sharing and circular references that occur naturally in object
-graphs. Subsequent references to an object use only the handle allowing a very
-compact representation.
-
-Special handling is required for arrays, enum constants, and objects of type
-`Class`, `ObjectStreamClass`, and `String`. Other objects must implement either
-the `Serializable` or the `Externalizable` interface to be saved in or restored
-from a stream.
-
-Primitive data types are written to the stream with the methods in the
-`DataOutput` interface, such as `writeInt`, `writeFloat`, or `writeUTF`.
-Individual bytes and arrays of bytes are written with the methods of
-`OutputStream`. Except for serializable fields, primitive data is written to
-the stream in block-data records, with each record prefixed by a marker and an
-indication of the number of bytes in the record.
-
-`ObjectOutputStream` can be extended to customize the information about classes
-in the stream or to replace objects to be serialized. Refer to the
-`annotateClass` and `replaceObject` method descriptions for details.
-
-## 1.3 Reading from an Object Stream
-
-Reading an object from a stream, like writing, is straightforward:
-
-```
-// Deserialize a string and date from a file.
- FileInputStream in = new FileInputStream("tmp");
- ObjectInputStream s = new ObjectInputStream(in);
- String today = (String)s.readObject();
- Date date = (Date)s.readObject();
-```
-
-First an `InputStream`, in this case a `FileInputStream`, is needed as the
-source stream. Then an `ObjectInputStream` is created that reads from the
-`InputStream`. Next, the string "Today" and a Date object are read from the
-stream. Generally, objects are read with the `readObject` method and primitives
-are read from the stream with the methods of `DataInput`.
-
-The `readObject` method deserializes the next object in the stream and
-traverses its references to other objects recursively to create the complete
-graph of objects serialized.
-
-Primitive data types are read from the stream with the methods in the
-`DataInput` interface, such as `readInt`, `readFloat`, or `readUTF`. Individual
-bytes and arrays of bytes are read with the methods of `InputStream`. Except
-for serializable fields, primitive data is read from block-data records.
-
-`ObjectInputStream` can be extended to utilize customized information in the
-stream about classes or to replace objects that have been deserialized. Refer
-to the `resolveClass` and `resolveObject` method descriptions for details.
-
-## 1.4 Object Streams as Containers
-
-Object Serialization produces and consumes a stream of bytes that contain one
-or more primitives and objects. The objects written to the stream, in turn,
-refer to other objects, which are also represented in the stream. Object
-Serialization produces just one stream format that encodes and stores the
-contained objects.
-
-Each object that acts as a container implements an interface which allows
-primitives and objects to be stored in or retrieved from it. These interfaces
-are the `ObjectOutput` and `ObjectInput` interfaces which:
-
-- Provide a stream to write to and to read from
-- Handle requests to write primitive types and objects to the stream
-- Handle requests to read primitive types and objects from the stream
-
-Each object which is to be stored in a stream must explicitly allow itself to
-be stored and must implement the protocols needed to save and restore its
-state. Object Serialization defines two such protocols. The protocols allow the
-container to ask the object to write and read its state.
-
-To be stored in an Object Stream, each object must implement either the
-`Serializable` or the `Externalizable` interface:
-
-- For a `Serializable` class, Object Serialization can automatically save and
- restore fields of each class of an object and automatically handle classes
- that evolve by adding fields or supertypes. A serializable class can
- declare which of its fields are saved or restored, and write and read
- optional values and objects.
-
-- For an `Externalizable` class, Object Serialization delegates to the class
- complete control over its external format and how the state of the
- supertype(s) is saved and restored.
-
-## 1.5 Defining Serializable Fields for a Class
-
-The serializable fields of a class can be defined two different ways. Default
-serializable fields of a class are defined to be the non-transient and
-non-static fields. This default computation can be overridden by declaring a
-special field in the `Serializable` class, `serialPersistentFields`. This field
-must be initialized with an array of `ObjectStreamField` objects that list the
-names and types of the serializable fields. The modifiers for the field are
-required to be private, static, and final. If the field's value is null or is
-otherwise not an instance of `ObjectStreamField[]`, or if the field does not
-have the required modifiers, then the behavior is as if the field were not
-declared at all.
-
-For example, the following declaration duplicates the default behavior.
-
-```
-class List implements Serializable {
- List next;
-
- private static final ObjectStreamField[] serialPersistentFields
- = {new ObjectStreamField("next", List.class)};
-
-}
-```
-
-By using `serialPersistentFields` to define the Serializable fields for a
-class, there no longer is a limitation that a serializable field must be a
-field within the current definition of the `Serializable` class. The
-`writeObject` and `readObject` methods of the `Serializable` class can map the
-current implementation of the class to the serializable fields of the class
-using the interface that is described in [Section 1.7, "Accessing Serializable
-Fields of a Class"](#accessing-serializable-fields-of-a-class). Therefore, the
-fields for a `Serializable` class can change in a later release, as long as it
-maintains the mapping back to its Serializable fields that must remain
-compatible across release boundaries.
-
-**Note:** There is, however, a limitation to the use of this mechanism to
-specify serializable fields for inner classes. Inner classes can only contain
-final static fields that are initialized to constants or expressions built up
-from constants. Consequently, it is not possible to set
-`serialPersistentFields` for an inner class (though it is possible to set it
-for static member classes). For other restrictions pertaining to serialization
-of inner class instances, see section [Section 1.10, "The Serializable
-Interface"](#the-serializable-interface).
-
-## 1.6 Documenting Serializable Fields and Data for a Class
-
-It is important to document the serializable state of a class to enable
-interoperability with alternative implementations of a Serializable class and
-to document class evolution. Documenting a serializable field gives one a final
-opportunity to review whether or not the field should be serializable. The
-serialization javadoc tags, `@serial`, `@serialField`, and `@serialData`,
-provide a way to document the serialized form for a Serializable class within
-the source code.
-
-- The `@serial` tag should be placed in the javadoc comment for a default
- serializable field. The syntax is as follows: `@serial` *field-description*
- The optional *field-description* describes the meaning of the field and its
- acceptable values. The *field-description* can span multiple lines. When a
- field is added after the initial release, a *@since* tag indicates the
- version the field was added. The *field-description* for `@serial` provides
- serialization-specific documentation and is appended to the javadoc comment
- for the field within the serialized form documentation.
-
-- The `@serialField` tag is used to document an `ObjectStreamField` component
- of a `serialPersistentFields` array. One of these tags should be used for
- each `ObjectStreamField` component. The syntax is as follows:
- `@serialField` *field-name field-type field-description*
-
-- The `@serialData` tag describes the sequences and types of data written or
- read. The tag describes the sequence and type of optional data written by
- `writeObject` or all data written by the `Externalizable.writeExternal`
- method. The syntax is as follows: `@serialData` *data-description*
-
-The javadoc application recognizes the serialization javadoc tags and generates
-a specification for each Serializable and Externalizable class. See [Section
-C.1, "Example Alternate Implementation of
-java.io.File"](examples.html#c.1-example-alternate-implementation-of-java.io.file)
-for an example that uses these tags.
-
-When a class is declared Serializable, the serializable state of the object is
-defined by serializable fields (by name and type) plus optional data. Optional
-data can only be written explicitly by the `writeObject` method of a
-`Serializable` class. Optional data can be read by the `Serializable` class'
-`readObject` method or serialization will skip unread optional data.
-
-When a class is declared Externalizable, the data that is written to the stream
-by the class itself defines the serialized state. The class must specify the
-order, types, and meaning of each datum that is written to the stream. The
-class must handle its own evolution, so that it can continue to read data
-written by and write data that can be read by previous versions. The class must
-coordinate with the superclass when saving and restoring data. The location of
-the superclasses data in the stream must be specified.
-
-The designer of a Serializable class must ensure that the information saved for
-the class is appropriate for persistence and follows the
-serialization-specified rules for interoperability and evolution. Class
-evolution is explained in greater detail in [Chapter
-5](version.html#versioning-of-serializable-objects), "Versioning of
-Serializable Objects".
-
-## 1.7 Accessing Serializable Fields of a Class
-
-Serialization provides two mechanisms for accessing the serializable fields in
-a stream:
-
-- The default mechanism requires no customization
-- The Serializable Fields API allows a class to explicitly access/set the
- serializable fields by name and type
-
-The default mechanism is used automatically when reading or writing objects
-that implement the `Serializable` interface and do no further customization.
-The serializable fields are mapped to the corresponding fields of the class and
-values are either written to the stream from those fields or are read in and
-assigned respectively. If the class provides `writeObject` and `readObject`
-methods, the default mechanism can be invoked by calling `defaultWriteObject`
-and `defaultReadObject`. When the `writeObject` and `readObject` methods are
-implemented, the class has an opportunity to modify the serializable field
-values before they are written or after they are read.
-
-When the default mechanism cannot be used, the serializable class can use the
-`putFields` method of `ObjectOutputStream` to put the values for the
-serializable fields into the stream. The `writeFields` method of
-`ObjectOutputStream` puts the values in the correct order, then writes them to
-the stream using the existing protocol for serialization. Correspondingly, the
-`readFields` method of `ObjectInputStream` reads the values from the stream and
-makes them available to the class by name in any order. See [Section 2.2, "The
-ObjectOutputStream.PutField
-Class"](output.html#the-objectoutputstream.putfield-class) and [Section 3.2,
-"The ObjectInputStream.GetField
-Class"](input.html#the-objectinputstream.getfield-class) for a detailed
-description of the Serializable Fields API.
-
-## 1.8 The ObjectOutput Interface
-
-The `ObjectOutput` interface provides an abstract, stream-based interface to
-object storage. It extends the DataOutput interface so those methods can be
-used for writing primitive data types. Objects that implement this interface
-can be used to store primitives and objects.
-
-```
-package java.io;
-
-public interface ObjectOutput extends DataOutput
-{
- public void writeObject(Object obj) throws IOException;
- public void write(int b) throws IOException;
- public void write(byte b[]) throws IOException;
- public void write(byte b[], int off, int len) throws IOException;
- public void flush() throws IOException;
- public void close() throws IOException;
-}
-```
-
-`The` `writeObject` method is used to write an object. The exceptions thrown
-reflect errors while accessing the object or its fields, or exceptions that
-occur in writing to storage. If any exception is thrown, the underlying storage
-may be corrupted. If this occurs, refer to the object that is implementing this
-interface for more information.
-
-## 1.9 The ObjectInput Interface
-
-The `ObjectInput` interface provides an abstract stream based interface to
-object retrieval. It extends the `DataInput` interface so those methods for
-reading primitive data types are accessible in this interface.
-
-```
-package java.io;
-
-public interface ObjectInput extends DataInput
-{
- public Object readObject()
- throws ClassNotFoundException, IOException;
- public int read() throws IOException;
- public int read(byte b[]) throws IOException;
- public int read(byte b[], int off, int len) throws IOException;
- public long skip(long n) throws IOException;
- public int available() throws IOException;
- public void close() throws IOException;
-}
-```
-
-The `readObject` method is used to read and return an object. The exceptions
-thrown reflect errors while accessing the objects or its fields or exceptions
-that occur in reading from the storage. If any exception is thrown, the
-underlying storage may be corrupted. If this occurs, refer to the object
-implementing this interface for additional information.
-
-## 1.10 The Serializable Interface
-
-Object Serialization produces a stream with information about the Java^TM^
-classes for the objects which are being saved. For serializable objects,
-sufficient information is kept to restore those objects even if a different
-(but compatible) version of the implementation of the class is present. The
-`Serializable` interface is defined to identify classes which implement the
-serializable protocol:
-
-```
-package java.io;
-
-public interface Serializable {};
-```
-
-A Serializable class must do the following:
-
-- Implement the `java.io.Serializable` interface
-
-- Identify the fields that should be serializable
-
- (Use the `serialPersistentFields` member to explicitly declare them
- serializable or use the transient keyword to denote nonserializable
- fields.)
-
-- Have access to the no-arg constructor of its first nonserializable
- superclass
-
-The class can optionally define the following methods:
-
-- A `writeObject` method to control what information is saved or to append
- additional information to the stream
-
-- A `readObject` method either to read the information written by the
- corresponding `writeObject` method or to update the state of the object
- after it has been restored
-
-- A `writeReplace` method to allow a class to nominate a replacement object
- to be written to the stream
-
- (See [Section 2.5, "The writeReplace
- Method"](output.html#the-writereplace-method) for additional information.)
-
-- A `readResolve` method to allow a class to designate a replacement object
- for the object just read from the stream
-
- (See [Section 3.7, "The readResolve
- Method](input.html#the-readresolve-method) for additional information.)
-
-`ObjectOutputStream` and `ObjectInputStream` allow the serializable classes on
-which they operate to evolve (allow changes to the classes that are compatible
-with the earlier versions of the classes). See [Section 5.5, "Compatible Java
-Type Evolution"](version.html#compatible-java-type-evolution) for information
-about the mechanism which is used to allow compatible changes.
-
-**Note:** Serialization of inner classes (i.e., nested classes that are not
-static member classes), including local and anonymous classes, is strongly
-discouraged for several reasons. Because inner classes declared in non-static
-contexts contain implicit non-transient references to enclosing class
-instances, serializing such an inner class instance will result in
-serialization of its associated outer class instance as well. Synthetic fields
-generated by `javac` (or other Java^TM^ compilers) to implement inner classes
-are implementation dependent and may vary between compilers; differences in
-such fields can disrupt compatibility as well as result in conflicting default
-`serialVersionUID` values. The names assigned to local and anonymous inner
-classes are also implementation dependent and may differ between compilers.
-Since inner classes cannot declare static members other than compile-time
-constant fields, they cannot use the `serialPersistentFields` mechanism to
-designate serializable fields. Finally, because inner classes associated with
-outer instances do not have zero-argument constructors (constructors of such
-inner classes implicitly accept the enclosing instance as a prepended
-parameter), they cannot implement `Externalizable`. None of the issues listed
-above, however, apply to static member classes.
-
-## 1.11 The Externalizable Interface
-
-For Externalizable objects, only the identity of the class of the object is
-saved by the container; the class must save and restore the contents. The
-`Externalizable` interface is defined as follows:
-
-```
-package java.io;
-
-public interface Externalizable extends Serializable
-{
- public void writeExternal(ObjectOutput out)
- throws IOException;
-
- public void readExternal(ObjectInput in)
- throws IOException, java.lang.ClassNotFoundException;
-}
-```
-
-The class of an Externalizable object must do the following:
-
-- Implement the `java.io.Externalizable` interface
-
-- Implement a `writeExternal` method to save the state of the object
-
- (It must explicitly coordinate with its supertype to save its state.)
-
-- Implement a `readExternal` method to read the data written by the
- `writeExternal` method from the stream and restore the state of the object
-
- (It must explicitly coordinate with the supertype to save its state.)
-
-- Have the `writeExternal` and `readExternal` methods be solely responsible
- for the format, if an externally defined format is written
-
- **Note:** The `writeExternal` and `readExternal` methods are public and
- raise the risk that a client may be able to write or read information in
- the object other than by using its methods and fields. These methods must
- be used only when the information held by the object is not sensitive or
- when exposing it does not present a security risk.
-
-- Have a public no-arg constructor
-
- **Note:** Inner classes associated with enclosing instances cannot have
- no-arg constructors, since constructors of such classes implicitly accept
- the enclosing instance as a prepended parameter. Consequently the
- `Externalizable` interface mechanism cannot be used for inner classes and
- they should implement the `Serializable` interface, if they must be
- serialized. Several limitations exist for serializable inner classes as
- well, however; see [Section 1.10, "The Serializable
- Interface"](#the-serializable-interface), for a full enumeration.
-
-An Externalizable class can optionally define the following methods:
-
-- A `writeReplace` method to allow a class to nominate a replacement object
- to be written to the stream
-
- (See [Section 2.5, "The writeReplace
- Method"](output.html#the-writereplace-method) for additional information.)
-
-- A `readResolve` method to allow a class to designate a replacement object
- for the object just read from the stream
-
- (See [Section 3.7, "The readResolve
- Method"](input.html#the-readresolve-method) for additional information.)
-
-## 1.12 Serialization of Enum Constants
-
-Enum constants are serialized differently than ordinary serializable or
-externalizable objects. The serialized form of an enum constant consists solely
-of its name; field values of the constant are not present in the form. To
-serialize an enum constant, `ObjectOutputStream` writes the value returned by
-the enum constant's `name` method. To deserialize an enum constant,
-`ObjectInputStream` reads the constant name from the stream; the deserialized
-constant is then obtained by calling the `java.lang.Enum.valueOf` method,
-passing the constant's enum type along with the received constant name as
-arguments. Like other serializable or externalizable objects, enum constants
-can function as the targets of back references appearing subsequently in the
-serialization stream.
-
-The process by which enum constants are serialized cannot be customized: any
-class-specific `writeObject`, `readObject`, `readObjectNoData`, `writeReplace`,
-and `readResolve` methods defined by enum types are ignored during
-serialization and deserialization. Similarly, any `serialPersistentFields` or
-`serialVersionUID` field declarations are also ignored--all enum types have a
-fixed `serialVersionUID` of `0L`. Documenting serializable fields and data for
-enum types is unnecessary, since there is no variation in the type of data
-sent.
-
-## 1.13 Protecting Sensitive Information
-
-When developing a class that provides controlled access to resources, care must
-be taken to protect sensitive information and functions. During
-deserialization, the private state of the object is restored. For example, a
-file descriptor contains a handle that provides access to an operating system
-resource. Being able to forge a file descriptor would allow some forms of
-illegal access, since restoring state is done from a stream. Therefore, the
-serializing runtime must take the conservative approach and not trust the
-stream to contain only valid representations of objects. To avoid compromising
-a class, the sensitive state of an object must not be restored from the stream,
-or it must be reverified by the class. Several techniques are available to
-protect sensitive data in classes.
-
-The easiest technique is to mark fields that contain sensitive data as *private
-transient*. Transient fields are not persistent and will not be saved by any
-persistence mechanism. Marking the field will prevent the state from appearing
-in the stream and from being restored during deserialization. Since writing and
-reading (of private fields) cannot be superseded outside of the class, the
-transient fields of the class are safe.
-
-Particularly sensitive classes should not be serialized at all. To accomplish
-this, the object should not implement either the `Serializable` or the
-`Externalizable` interface.
-
-Some classes may find it beneficial to allow writing and reading but
-specifically handle and revalidate the state as it is deserialized. The class
-should implement `writeObject` and `readObject` methods to save and restore
-only the appropriate state. If access should be denied, throwing a
-`NotSerializableException` will prevent further access.

-
-## 5.1 Overview
-
-When Java objects use serialization to save state in files, or as blobs in
-databases, the potential arises that the version of a class reading the data is
-different than the version that wrote the data.
-
-Versioning raises some fundamental questions about the identity of a class,
-including what constitutes a compatible change. A ***compatible change*** is a
-change that does not affect the contract between the class and its callers.
-
-This section describes the goals, assumptions, and a solution that attempts to
-address this problem by restricting the kinds of changes allowed and by
-carefully choosing the mechanisms.
-
-The proposed solution provides a mechanism for "automatic" handling of classes
-that evolve by adding fields and adding classes. Serialization will handle
-versioning without class-specific methods to be implemented for each version.
-The stream format can be traversed without invoking class-specific methods.
-
-## 5.2 Goals
-
-The goals are to:
-
-- Support bidirectional communication between different versions of a class
- operating in different virtual machines by:
-
- - Defining a mechanism that allows Java classes to read streams written
- by older versions of the same class.
-
- - Defining a mechanism that allows Java classes to write streams intended
- to be read by older versions of the same class.
-
-- Provide default serialization for persistence and for RMI.
-
-- Perform well and produce compact streams in simple cases, so that RMI can
- use serialization.
-
-- Be able to identify and load classes that match the exact class used to
- write the stream.
-
-- Keep the overhead low for nonversioned classes.
-
-- Use a stream format that allows the traversal of the stream without having
- to invoke methods specific to the objects saved in the stream.
-
-## 5.3 Assumptions
-
-The assumptions are that:
-
-- Versioning will only apply to serializable classes since it must control
- the stream format to achieve it goals. Externalizable classes will be
- responsible for their own versioning which is tied to the external format.
-
-- All data and objects must be read from, or skipped in, the stream in the
- same order as they were written.
-
-- Classes evolve individually as well as in concert with supertypes and
- subtypes.
-
-- Classes are identified by name. Two classes with the same name may be
- different versions or completely different classes that can be
- distinguished only by comparing their interfaces or by comparing hashes of
- the interfaces.
-
-- Default serialization will not perform any type conversions.
-
-- The stream format only needs to support a linear sequence of type changes,
- not arbitrary branching of a type.
-
-## 5.4 Who's Responsible for Versioning of Streams
-
-In the evolution of classes, it is the responsibility of the evolved (later
-version) class to maintain the contract established by the nonevolved class.
-This takes two forms. First, the evolved class must not break the existing
-assumptions about the interface provided by the original version, so that the
-evolved class can be used in place of the original. Secondly, when
-communicating with the original (or previous) versions, the evolved class must
-provide sufficient and equivalent information to allow the earlier version to
-continue to satisfy the nonevolved contract.
-
-> 
-
-For the purposes of the discussion here, each class implements and extends the
-interface or contract defined by its supertype. New versions of a class, for
-example `foo'`, must continue to satisfy the contract for `foo` and may extend
-the interface or modify its implementation.
-
-Communication between objects via serialization is not part of the contract
-defined by these interfaces. Serialization is a private protocol between the
-implementations. It is the responsibility of the implementations to communicate
-sufficiently to allow each implementation to continue to satisfy the contract
-expected by its clients.
-
-## 5.5 Compatible Java Type Evolution
-
-The Java Language Specification discusses binary compatibility of Java classes
-as those classes evolve. Most of the flexibility of binary compatibility comes
-from the use of late binding of symbolic references for the names of classes,
-interfaces, fields, methods, and so on.
-
-The following are the principle aspects of the design for versioning of
-serialized object streams.
-
-- The default serialization mechanism will use a symbolic model for binding
- the fields in the stream to the fields in the corresponding class in the
- virtual machine.
-
-- Each class referenced in the stream will uniquely identify itself, its
- supertype, and the types and names of each serializable field written to
- the stream. The fields are ordered with the primitive types first sorted by
- field name, followed by the object fields sorted by field name.
-
-- Two types of data may occur in the stream for each class: required data
- (corresponding directly to the serializable fields of the object); and
- optional data (consisting of an arbitrary sequence of primitives and
- objects). The stream format defines how the required and optional data
- occur in the stream so that the whole class, the required, or the optional
- parts can be skipped if necessary.
-
- - The required data consists of the fields of the object in the order
- defined by the class descriptor.
-
- - The optional data is written to the stream and does not correspond
- directly to fields of the class. The class itself is responsible for
- the length, types, and versioning of this optional information.
-
-- If defined for a class, the `writeObject`/`readObject` methods supersede
- the default mechanism to write/read the state of the class. These methods
- write and read the optional data for a class. The required data is written
- by calling `defaultWriteObject` and read by calling `defaultReadObject`.
-
-- The stream format of each class is identified by the use of a Stream Unique
- Identifier (SUID). By default, this is the hash of the class. All later
- versions of the class must declare the Stream Unique Identifier (SUID) that
- they are compatible with. This guards against classes with the same name
- that might inadvertently be identified as being versions of a single class.
-
-- Subtypes of `ObjectOutputStream` and `ObjectInputStream` may include their
- own information identifying the class using the `annotateClass` method; for
- example, `MarshalOutputStream` embeds the URL of the class.
-
-## 5.6 Type Changes Affecting Serialization
-
-With these concepts, we can now describe how the design will cope with the
-different cases of an evolving class. The cases are described in terms of a
-stream written by some version of a class. When the stream is read back by the
-same version of the class, there is no loss of information or functionality.
-The stream is the only source of information about the original class. Its
-class descriptions, while a subset of the original class description, are
-sufficient to match up the data in the stream with the version of the class
-being reconstituted.
-
-The descriptions are from the perspective of the stream being read in order to
-reconstitute either an earlier or later version of the class. In the parlance
-of RPC systems, this is a "receiver makes right" system. The writer writes its
-data in the most suitable form and the receiver must interpret that information
-to extract the parts it needs and to fill in the parts that are not available.
-
-### 5.6.1 Incompatible Changes
-
-Incompatible changes to classes are those changes for which the guarantee of
-interoperability cannot be maintained. The incompatible changes that may occur
-while evolving a class are:
-
-- Deleting fields - If a field is deleted in a class, the stream written will
- not contain its value. When the stream is read by an earlier class, the
- value of the field will be set to the default value because no value is
- available in the stream. However, this default value may adversely impair
- the ability of the earlier version to fulfill its contract.
-
-- Moving classes up or down the hierarchy - This cannot be allowed since the
- data in the stream appears in the wrong sequence.
-
-- Changing a nonstatic field to static or a nontransient field to transient -
- When relying on default serialization, this change is equivalent to
- deleting a field from the class. This version of the class will not write
- that data to the stream, so it will not be available to be read by earlier
- versions of the class. As when deleting a field, the field of the earlier
- version will be initialized to the default value, which can cause the class
- to fail in unexpected ways.
-
-- Changing the declared type of a primitive field - Each version of the class
- writes the data with its declared type. Earlier versions of the class
- attempting to read the field will fail because the type of the data in the
- stream does not match the type of the field.
-
-- Changing the `writeObject` or `readObject` method so that it no longer
- writes or reads the default field data or changing it so that it attempts
- to write it or read it when the previous version did not. The default field
- data must consistently either appear or not appear in the stream.
-
-- Changing a class from `Serializable` to `Externalizable` or vice versa is
- an incompatible change since the stream will contain data that is
- incompatible with the implementation of the available class.
-
-- Changing a class from a non-enum type to an enum type or vice versa since
- the stream will contain data that is incompatible with the implementation
- of the available class.
-
-- Removing either `Serializable` or `Externalizable` is an incompatible
- change since when written it will no longer supply the fields needed by
- older versions of the class.
-
-- Adding the `writeReplace` or `readResolve` method to a class is
- incompatible if the behavior would produce an object that is incompatible
- with any older version of the class.
-
-### 5.6.2 Compatible Changes
-
-The compatible changes to a class are handled as follows:
-
-- Adding fields - When the class being reconstituted has a field that does
- not occur in the stream, that field in the object will be initialized to
- the default value for its type. If class-specific initialization is needed,
- the class may provide a readObject method that can initialize the field to
- nondefault values.
-
-- Adding classes - The stream will contain the type hierarchy of each object
- in the stream. Comparing this hierarchy in the stream with the current
- class can detect additional classes. Since there is no information in the
- stream from which to initialize the object, the class's fields will be
- initialized to the default values.
-
-- Removing classes - Comparing the class hierarchy in the stream with that of
- the current class can detect that a class has been deleted. In this case,
- the fields and objects corresponding to that class are read from the
- stream. Primitive fields are discarded, but the objects referenced by the
- deleted class are created, since they may be referred to later in the
- stream. They will be garbage-collected when the stream is garbage-collected
- or reset.
-
-- Adding `writeObject`/`readObject` methods - If the version reading the
- stream has these methods then `readObject` is expected, as usual, to read
- the required data written to the stream by the default serialization. It
- should call `defaultReadObject` first before reading any optional data. The
- `writeObject` method is expected as usual to call `defaultWriteObject` to
- write the required data and then may write optional data.
-
-- Removing `writeObject`/`readObject` methods - If the class reading the
- stream does not have these methods, the required data will be read by
- default serialization, and the optional data will be discarded.
-
-- Adding `java.io.Serializable` - This is equivalent to adding types. There
- will be no values in the stream for this class so its fields will be
- initialized to default values. The support for subclassing nonserializable
- classes requires that the class's supertype have a no-arg constructor and
- the class itself will be initialized to default values. If the no-arg
- constructor is not available, the `InvalidClassException` is thrown.
-
-- Changing the access to a field - The access modifiers public, package,
- protected, and private have no effect on the ability of serialization to
- assign values to the fields.
-
-- Changing a field from static to nonstatic or transient to nontransient -
- When relying on default serialization to compute the serializable fields,
- this change is equivalent to adding a field to the class. The new field
- will be written to the stream but earlier classes will ignore the value
- since serialization will not assign values to static or transient fields.

-<title>Java AWT Native Interface Specification and Guide</title>
-</head>
-<body>
-<h2>The Java AWT Native Interface Specification and Guide</h2>
-<h3>Introduction</h3>
-<p>The Java AWT Native Interface (JAWT) comprises a small set of native
-(eg C language-based) APIs that provide a standard supported way
-for interaction between Java API windows and surfaces, and
-platform native API windows and surfaces.
-Non-Java libraries may then render to a Java owned window.
-<p>
-Note: in this document the terms "Java AWT Native Interface",
-"AWT Native Interface" and "JAWT" are interchangeable and
-refer to this same specification.
-<p>
-The fundamental obstacle to native rendering without JAWT is that
-is that the rendering code cannot identify where to draw.
-The native code needs access to information about a Java
-drawing surface (such as a handle to the underlying native ID of a
-<tt>Canvas</tt>), but cannot get it.</p>
-Without that information (ie without JAWT) an application could
-use native rendering only by creating its own top-level window
-not shared at all with Java. This is unacceptable for most uses.
-Except for usage via JAWT, this is considered to be entirely
-internal to the Java platform implementation: private, unsupported
-and undocumented.
-<p>
-JAWT should be supported in all headful implementations
-where technically possible although this is not enforced by the JCK.
-There is a platform-specific and a platform
-independent portion to the API, to account for the differing
-data structures and requirements of each platform.
-This document specifies the platform independent portions and
-also documents the platform dependent portions for the Oracle JDK
-supported desktop operating environments.
-For AWT the term platform is less tied to the underlying operating
-system than it is to the desktop windowing environment.
-<p>
-Reasons for using the AWT Native Interface include
-<ul>
-<li>Use of a 3rd party native library not available in Java
-<li>A temporary porting aid before converting legacy code to Java
-<li>Rendering performance available only to native hardware accelerated APIs
-<li>Interoperation with another toolkit
-</ul>
-<p>
-Drawbacks include
-<ul>
-<li>A more complex application implementation, eg for painting
-<li>Potential for application instability if the native library does
-not interoperate properly with AWT.
-<li>Increased application delivery complexity - per platform binaries
-</ul>
-The header file <a href="#jawt.h"> "jawt.h"</a>
-in the Appendix fully specifies the APIs provided by JAWT.
-<p>
-An example illustrating how easy it is to use the AWT Native Interface
-is presented and discussed later in this document.</p>
-
-<p><b>JAWT usage depends on JNI</b></p>
-<p>The definition of Java Standard Edition includes JNI, the Java
-Native Interface. Many Java developers will never need to use it,
-but the interface is the only standard supported way for a Java
-language program to interact directly with
-application code that has been compiled to the native machine
-instructions for the host processor architecture.
-JNI is used where ever there is a need for mixed languages.
-These are by no means limited to cases like AWT. For example, you
-could use JNI to integrate with native code that communicates with
-a peripheral device, such as a scanner, connected to a system via a
-USB port.</p>
-<p>So JNI is general enough to be used to access almost any
-sort of native library.
-The rest of this document assumes a familiarity with how
-to use JNI.
-
-<p><b>How to use JAWT </b></p>
-<p>In this section we describe the most common usage of the AWT
-Native Interface — overriding the <tt>paint</tt> method to
-direct drawing operations to a native rendering library which then
-queries the Java VM to determine the information it needs in order
-to render. Note, however, that any native code may use the AWT
-Native Interface to learn about a target drawing surface, not just
-code in a <tt>paint</tt> method.</p>
-<p>The first step in hooking up a native rendering library to a
-Java <tt>Canvas</tt> is to define a new class that extends
-<tt>Canvas</tt> and overrides the <tt>paint</tt> method. The Java
-system routes all drawing operations for a <tt>Canvas</tt> object
-through the <tt>paint</tt> method, as it does for all other GUI
-objects. Canvas is a good candidate for the rendering surface as
-it does not have any content as a Button would.</p>
-<p>The new <tt>paint</tt> method, to be implemented in the native
-rendering library, must be declared as <tt>public native void</tt>
-, and the native library itself is loaded at runtime by including a
-call to <tt>System.loadLibrary( "myRenderingLib")</tt>in
-the <tt>static</tt> block of the class. The <tt>myRenderingLib</tt>
-name is used for the native shared library; for Linux or the Solaris
-operating environment, the actual name for the library file on disk
-is <tt>libmyRenderingLib.so</tt> .</p>
-<p>Here is a simple example of such a class:</p>
-<pre>
-import java.awt.*;
-import java.awt.event.*;
-
-public class MyCanvas extends Canvas {
- static {
- System.loadLibrary("myRenderingLib");
- }
- public native void paint(Graphics g);
-
- public static void main(String[] args) {
- Frame f = new Frame();
- f.setBounds(0, 0, 500, 110);
- f.add(new MyCanvas());
- f.addWindowListener( new WindowAdapter() {
- public void windowClosing(WindowEvent ev) {
- System.exit(0);
- }
- } );
- f.show();
- }
-}
-<br />
-</pre>
-<p>Note that this class has a <tt>main</tt> method that can be used
-to run this code as an application for testing purposes.</p>
-<p>The next step is to run the <tt>javah</tt> tool on the
-<tt>MyCanvas</tt> class file above to generate a C/C++ header file
-that describes the interface to the native <tt>paint</tt> method
-that Java expects to be used. <tt>javah</tt> is a standard tool
-included with the JDK. NB: <tt>javac -h outputdir</tt> may also be used.</p>
-
-<p>The final step ­ and the most interesting one ­ is to
-write the native rendering method, with an interface that conforms
-to the header file that <tt>javah</tt> generated, and build it as a
-standard shared library (called <tt>myRenderingLib</tt> in the
-above example) by linking it, against the appropriate JDK provided
-$JDK_HOME/lib/$JAWT_LIB library for the target platform.
-Where JAWT_LIB has the base name "jawt" and follows platform
-shared object naming rules. i.e.:
-<ul>
-<li>Windows: jawt.dll
-<li>MacOS: libjawt.dylib
-<li>Linux: libjawt.so
-<li>Solaris: libjawt.so
-</ul>
-
-This code will call back to the Java virtual machine to
-get the drawing surface information it needs to access the
-<tt>MyCanvas</tt> peer. Once this information is available, the
-code can draw directly to <tt>MyCanvas</tt> using standard drawing
-routines supplied by the underlying operating system.</p>
-<p>Here is sample source code for a native <tt>paint</tt> method
-designed for use in a X11-based drawing environment (Linux
-or Solaris) and a Java VM where the AWT Native Interface is present:</p>

-<p>The key data structure here is <tt>JAWT</tt> , which is defined
-in <tt>jawt.h</tt> (included by <tt>jawt_md.h)</tt> ; it provides
-access to all the information the native code needs to get the job
-done. The first part of the native method is boilerplate: it
-populates the <tt>JAWT</tt> structure, gets a
-<tt>JAWT_DrawingSurface</tt> structure, locks the surface (only one
-drawing engine at a time, please!), then gets a
-<tt>JAWT_DrawingSurfaceInfo</tt> structure that contains a pointer
-(in the <tt>platformInfo</tt> field) to the necessary
-platform-specific drawing information. It also includes the
-bounding rectangle of the drawing surface and the current clipping
-region.</p>
-<p>The structure of the information pointed to by
-<tt>platformInfo</tt> is defined in a machine-dependent header file
-called <tt>jawt_md.h</tt>. For X11 drawing, it includes
-information about the X11 display and X11 drawable associated with
-<tt>MyCanvas</tt>. After the drawing operations are completed,
-there is more boilerplate code as <tt>JAWT_DrawingSurfaceInfo</tt>
-is freed and <tt>JAWT_DrawingSurface</tt> is unlocked and
-freed.</p>
-<p>The corresponding code for the GDI API on the Microsoft Windows platform would
-be structured similarly, but would include the version of
-<tt>jawt_md.h</tt> for Microsoft Windows and the structure located
-in the <tt>platformInfo</tt> field of drawing surface info would be
-cast as a <tt>JAWT_Win32DrawingSurfaceInfo*</tt> . And, of course,
-the actual drawing operations would need to be changed to those
-appropriate for the Microsoft Windows platform.
-The same also for MacOS.
-</p>
-<p><b>Summary</b></p>
-<p>The ability to draw directly into a Java <tt>Canvas</tt> from a
-native code library is extremely useful for developers planning to
-migrate a legacy software system to Java, especially one that
-includes a high-performance rendering engine. It makes it much
-easier to migrate in stages, leaving performance-sensitive
-rendering code alone, while other less-sensitive portions of code
-are converted to Java. The result can be a modern Java-centric
-application, providing the benefit of portability and development
-efficiency, but one that does not sacrifice an investment in
-performance of a key piece of native code.</p>

- * AWT native interface.
- *
- * The AWT native interface allows a native C or C++ application a means
- * by which to access native structures in AWT. This is to facilitate moving
- * legacy C and C++ applications to Java and to target the needs of the
- * developers who need to do their own native rendering to canvases
- * for performance or other reasons.
- *
- * Conversely it also provides mechanisms for an application which already
- * has a native window to provide that to AWT for AWT rendering.
- *
- * Since every platform may be different in its native data structures
- * and APIs for windowing systems the application must necessarily
- * provided per-platform source and compile and deliver per-platform
- * native code to use this API.
- *
- * These interfaces are not part of the Java SE specification and
- * a VM is not required to implement this API. However it is strongly
- * recommended that all implementations which support headful AWT
- * also support these interfaces.
- *
- */
-
-/*
- * AWT Native Drawing Surface (JAWT_DrawingSurface).
- *
- * For each platform, there is a native drawing surface structure. This
- * platform-specific structure can be found in jawt_md.h. It is recommended
- * that additional platforms follow the same model. It is also recommended
- * that VMs on all platforms support the existing structures in jawt_md.h.

- *******************
- * EXAMPLE OF USAGE:
- *******************
- *
- * On Microsoft Windows, a programmer wishes to access the HWND of a canvas
- * to perform native rendering into it. The programmer has declared the
- * paint() method for their canvas subclass to be native:
- *
- *
- * MyCanvas.java:
- *
- * import java.awt.*;
- *
- * public class MyCanvas extends Canvas {
- *
- * static {
- * System.loadLibrary("mylib");
- * }
- *
- * public native void paint(Graphics g);
- * }
- *
- *
- * myfile.c:
- *
- * #include "jawt_md.h"
- * #include <assert.h>
- *
- * JNIEXPORT void JNICALL
- * Java_MyCanvas_paint(JNIEnv* env, jobject canvas, jobject graphics)
- * {
- * JAWT awt;
- * JAWT_DrawingSurface* ds;
- * JAWT_DrawingSurfaceInfo* dsi;
- * JAWT_Win32DrawingSurfaceInfo* dsi_win;
- * jboolean result;
- * jint lock;
- *
- * // Get the AWT. Request version 9 to access features in that release.
- * awt.version = JAWT_VERSION_9;
- * result = JAWT_GetAWT(env, &awt);
- * assert(result != JNI_FALSE);
- *
- * // Get the drawing surface
- * ds = awt.GetDrawingSurface(env, canvas);
- * assert(ds != NULL);
- *
- * // Lock the drawing surface
- * lock = ds->Lock(ds);
- * assert((lock & JAWT_LOCK_ERROR) == 0);
- *
- * // Get the drawing surface info
- * dsi = ds->GetDrawingSurfaceInfo(ds);
- *
- * // Get the platform-specific drawing info
- * dsi_win = (JAWT_Win32DrawingSurfaceInfo*)dsi->platformInfo;
- *
- * //////////////////////////////
- * // !!! DO PAINTING HERE !!! //
- * //////////////////////////////
- *
- * // Free the drawing surface info
- * ds->FreeDrawingSurfaceInfo(dsi);
- *
- * // Unlock the drawing surface

- "Copyright 2004 Sun Microsystems, Inc. All rights reserved.
-
- This module defines the MIB that provides access to the
- Java[tm] Virtual Machine monitoring data.
- This module is derived from the Java[tm] programming language APIs
- described in the java.lang.management package of
- Java[tm] 2, Standard Edition, 5.0.
-
- See the Java programming language APIs of JSR 163 for
- 'Monitoring and Management of the Java[TM] Virtual Machine'
- for more details.
-
- Where the Java programming language API uses long, or int,
- the MIB often uses the corresponding unsigned quantity -
- which is closer to the object semantics.
-
- In those cases, it often happens that the -1 value that might
- be used by the API to indicate an unknown/unimplemented
- value cannot be used. Instead the MIB uses the value 0, which
- stricly speaking cannot be distinguished from a valid value.
- In many cases however, a running system will have non-zero
- values, so using 0 instead of -1 to indicate an unknown
- quantity does not lose any functionality.

--- Textual Conventions
-----------------------
---
--- Note: Some of the TEXTUAL-CONVENTIONs defined in this module are
--- OCTET STRING with a 1023 size limitation (SIZE(0..1023)).
---
--- As per RFC2578, section 7.1.2. OCTET STRING:
---
--- "The OCTET STRING type represents arbitrary binary or textual data.
--- Although the SMI-specified size limitation for this type is 65535
--- octets, MIB designers should realize that there may be
--- implementation and interoperability limitations for sizes in
--- excess of 255 octets."
---
--- As a consequence an agent implementing this MIB may decide to
--- restrict this maximum size to a lesser value than 1023, provided that
--- it makes it clear in an AGENT-CAPABILITY statement.

--- The JVM Memory group
---
--- A collection of objects used to monitor memory management in the
--- Java Virtual Machine. These objects define management interface for
--- the memory system of the Java virtual machine.
---
--- Memory:
---
--- The memory system of the Java virtual machine manages the following
--- kinds of memory: heap, and non-heap. More information on these types
--- of memory can be obtained from the J2SE 5.0 API Specification,
--- java.lang.management.MemoryMXBean.
---
--- Memory Pools and Memory Managers:
---
--- Memory pools and memory managers are the abstract entities that monitor
--- and manage the memory system of the Java virtual machine.
---
--- Memory managers are represented by the jvmMemManagerTable, which contains
--- one row per Memory manager.
--- The garbage collector is one type of memory manager responsible for
--- reclaiming memory occupied by unreachable objects.
--- The jvmMemGCTable is an extension of the jvmMemManagerTable, which contains
--- the attribute specific to garbage collectors. A garbage collector entity
--- is thus represented by one row in the jvmMemManagerTable, and one
--- extension row in the jvmMemGCTable.
---
--- Memory Pools are represented by the jvmMemPoolTable, which contains one
--- row per memory pool. A Java virtual machine may create or remove
--- memory pools during execution. A memory pool can belong to either the
--- heap or the non-heap memory.
---
--- A memory manager is responsible for managing one or more memory pools.
--- A memory pool can be managed by more than one memory manager.
--- The jvmMemMgrRelPoolTable represents this managing/managed relationship.
---
--- A Java virtual machine may add or remove memory managers during execution.
---
--- See J2SE 5.0 API Specification, java.lang.management.MemoryMXBean for
--- more information on memory types, memory managers, memory pools,
--- and the memory subsystem.

- This object indicates the last time - in milliseconds - at which
- the peak thread count was reset to the current thread count.
- This corresponds to a time stamp as returned by
- java.lang.System.currentTimeMillis().
-
- Setting this object to a time earlier than its current time value
- has no effect. Setting this object to a time later than its current
- time value causes the peak thread count statistic to be reset to
- the current thread count. The new value of this object will be
- the time at which the reset operation is triggered.
-
- There could be a delay between the time at which the reset operation
- is triggered and the time at which the actual resetting happens, so
- this value is only indicative.
