/**
- * The configuration that is the result of resolution or resolution with
- * service binding.
- *
- *
Resolution is the process of computing the transitive closure of a set
- * of root modules over a set of observable modules by resolving the
- * dependences expressed by {@code requires} clauses.
- *
- * The dependence graph is augmented with edges that take account of
- * implicitly declared dependences ({@code requires transitive}) to create a
- * readability graph. A {@code Configuration} encapsulates the
- * resulting graph of {@link ResolvedModule resolved modules}.
- *
- *
If the module {@code m1} is resolved then the resulting configuration
- * contains three modules ({@code m1}, {@code m2}, {@code m3}). The edges in
- * its readability graph are:
Resolution is an additive process. When computing the transitive closure
- * then the dependence relation may include dependences on modules in parent
- * configurations. The result is a relative configuration that is
- * relative to one or more parent configurations and where the readability graph
- * may have edges from modules in the configuration to modules in parent
- * configurations.
- *
- *
A configuration encapsulates the readability graph that is the
+ * output of resolution. A readability graph is a directed graph where the nodes
+ * are of type {@link ResolvedModule} and the edges represent the readability
+ * amongst the modules. {@code Configuration} defines the {@link #modules()
+ * modules()} method to get the set of resolved modules in the graph. {@code
+ * ResolvedModule} defines the {@link ResolvedModule#reads() reads()} method to
+ * get the set of modules that a resolved module reads. The modules that are
+ * read may be in the same configuration or may be in {@link #parents() parent}
+ * configurations.
*
- *
If module {@code m1} is resolved with the configuration for the {@link
- * java.lang.reflect.Layer#boot() boot} layer as the parent then the resulting
- * configuration contains two modules ({@code m1}, {@code m2}). The edges in
- * its readability graph are:
- *
{@code
- * m1 --> m2
- * m1 --> java.xml
- * }
- * where module {@code java.xml} is in the parent configuration. For
- * simplicity, this example omits the implicitly declared dependence on the
- * {@code java.base} module.
- *
- *
- *
{@link ModuleDescriptor#isAutomatic() Automatic} modules receive special
- * treatment during resolution. Each automatic module is resolved so that it
- * reads all other modules in the configuration and all parent configurations.
- * Each automatic module is also resolved as if it {@code requires transitive}
- * all other automatic modules in the configuration (and all automatic modules
- * in parent configurations).
Configuration defines the {@link #resolve(ModuleFinder,List,ModuleFinder,Collection)
+ * resolve} method to resolve a collection of root modules, and the {@link
+ * #resolveAndBind(ModuleFinder,List,ModuleFinder,Collection) resolveAndBind}
+ * method to do resolution with service binding. There are instance and
+ * static variants of both methods. The instance methods create a configuration
+ * with the receiver as the parent configuration. The static methods are for
+ * more advanced cases where there can be more than one parent configuration.
*
- *
Service binding is the process of augmenting a graph of resolved modules
- * from the set of observable modules induced by the service-use dependence
- * ({@code uses} and {@code provides} clauses). Any module that was not
- * previously in the graph requires resolution to compute its transitive
- * closure. Service binding is an iterative process in that adding a module
- * that satisfies some service-use dependence may introduce new service-use
- * dependences.
If the module {@code m1} is resolved then the resulting graph of modules
- * has one module ({@code m1}). If the graph is augmented with modules induced
- * by the service-use dependence relation then the configuration will contain
- * four modules ({@code m1}, {@code m2}, {@code m3}, {@code m4}). The edges in
- * its readability graph are:
The edges in the conceptual service-use graph are:
- *
{@code
- * m1 --> m2 (meaning m1 uses a service that is provided by m2)
- * m1 --> m3
- * }
- *
- *
If this configuration is instantiated as a {@code Layer}, and if code in
- * module {@code m1} uses {@link java.util.ServiceLoader ServiceLoader} to
- * iterate over implementations of {@code p.S.class}, then it will iterate over
- * an instance of {@code p2.S2} and {@code p3.S3}.
+ *
Each {@link java.lang.reflect.Layer layer} of modules in the Java virtual
+ * machine is created from a configuration. The configuration for the {@link
+ * java.lang.reflect.Layer#boot() boot} layer is obtained by invoking {@code
+ * Layer.boot().configuration()}. The configuration for the boot layer will
+ * often be the parent when creating new configurations.
*
*
Example
*
- *
The following example uses the {@code resolveRequires} method to resolve
- * a module named myapp with the configuration for the boot layer as
- * the parent configuration. It prints the name of each resolved module and
- * the names of the modules that each module reads.
+ *
The following example uses the {@link
+ * #resolve(ModuleFinder,ModuleFinder,Collection) resolve} method to resolve a
+ * module named myapp with the configuration for the boot layer as the
+ * parent configuration. It prints the name of each resolved module and the

/**
* A module descriptor.
*
- *
A {@code ModuleDescriptor} is typically created from the binary form
- * of a module declaration. Alternatively, the {@link ModuleDescriptor.Builder}
- * class can be used to create a {@code ModuleDescriptor} from its components.
- * The {@link #module module}, {@link #openModule openModule}, and {@link
- * #automaticModule automaticModule} methods create builders for building
- * different kinds of modules.
+ *
A module descriptor describes a named module and defines methods to
+ * obtain each of its components. The module descriptor for a named module
+ * in the Java virtual machine is obtained by invoking the {@link
+ * java.lang.reflect.Module Module}'s {@link java.lang.reflect.Module#getDescriptor
+ * getDescriptor} method. Module descriptors can also be created using the
+ * {@link ModuleDescriptor.Builder} class or by reading the binary form of a
+ * module declaration ({@code module-info.class}) using the {@link
+ * #read(InputStream,Supplier) read} methods defined here.
+ *
+ *
A module descriptor describes a normal, open, or automatic
+ * module. Normal modules and open modules describe their {@link
+ * #requires() dependences}, {@link #exports() exported-packages}, the services
+ * that they {@link #uses() use} or {@link #provides() provide}, and other
+ * components. Normal modules may {@link #opens() open} specific
+ * packages. The module descriptor for an open modules does not declare any
+ * open packages (its {@code opens} method returns an empty set) but when
+ * instantiated in the Java virtual machine then it is treated as if all
+ * packages are open. The module descriptor for an automatic module does not
+ * declare any dependences (except for the mandatory dependency on {@code
+ * java.base}), and does not declare any exported or open packages. Automatic
+ * module receive special treatment during resolution so that they read all
+ * other modules in the configuration. When an automatic module is instantiated
+ * in the Java virtual machine then it reads every unnamed module and is
+ * treated as if all packages are exported and open.
*
*
{@code ModuleDescriptor} objects are immutable and safe for use by
* multiple concurrent threads.

* Classes to support module descriptors and creating configurations of modules
* by means of resolution and service binding.
*
+ *
Resolution is the process of computing the transitive closure of a set
+ * of root modules over a set of observable modules by resolving the
+ * dependences expressed by {@link
+ * java.lang.module.ModuleDescriptor.Requires requires} clauses.
+ * The dependence graph is augmented with edges that take account of
+ * implicitly declared dependences ({@code requires transitive}) to create a
+ * readability graph. The result of resolution is a {@link
+ * java.lang.module.Configuration Configuration} that encapsulates the
+ * readability graph.
+ *
+ *
As an example, suppose we have the following observable modules:
If the module {@code m1} is resolved then the resulting configuration
+ * contains three modules ({@code m1}, {@code m2}, {@code m3}). The edges in
+ * its readability graph are:
Resolution is an additive process. When computing the transitive closure
+ * then the dependence relation may include dependences on modules in {@link
+ * java.lang.module.Configuration#parents() parent} configurations. The result
+ * is a relative configuration that is relative to one or more parent
+ * configurations and where the readability graph may have edges from modules
+ * in the configuration to modules in parent configurations.
+ *
+ *
As an example, suppose we have the following observable modules:
If module {@code m1} is resolved with the configuration for the {@link
+ * java.lang.reflect.Layer#boot() boot} layer as the parent then the resulting
+ * configuration contains two modules ({@code m1}, {@code m2}). The edges in
+ * its readability graph are:
+ *
{@code
+ * m1 --> m2
+ * m1 --> java.xml
+ * }
+ * where module {@code java.xml} is in the parent configuration. For
+ * simplicity, this example omits the implicitly declared dependence on the
+ * {@code java.base} module.
+ *
+ *
Requires clauses that are "{@code requires static}" express an optional
+ * dependence (except at compile-time). If a module declares that it
+ * "{@code requires static M}" then resolution does not search the observable
+ * modules for "{@code M}". However, if "{@code M}" is resolved (because resolution
+ * resolves a module that requires "{@code M}" without the {@link
+ * java.lang.module.ModuleDescriptor.Requires.Modifier#STATIC static} modifier)
+ * then the readability graph will contain read edges for each module that
+ * "{@code requires static M}".
+ *
+ *
{@link java.lang.module.ModuleDescriptor#isAutomatic() Automatic} modules
+ * receive special treatment during resolution. Each automatic module is resolved
+ * so that it reads all other modules in the configuration and all parent
+ * configurations. Each automatic module is also resolved as if it
+ * "{@code requires transitive}" all other automatic modules in the configuration
+ * (and all automatic modules in parent configurations).
Service binding is the process of augmenting a graph of resolved modules
+ * from the set of observable modules induced by the service-use dependence
+ * ({@code uses} and {@code provides} clauses). Any module that was not
+ * previously in the graph requires resolution to compute its transitive
+ * closure. Service binding is an iterative process in that adding a module
+ * that satisfies some service-use dependence may introduce new service-use
+ * dependences.
If the module {@code m1} is resolved then the resulting graph of modules
+ * has one module ({@code m1}). If the graph is augmented with modules induced
+ * by the service-use dependence relation then the configuration will contain
+ * four modules ({@code m1}, {@code m2}, {@code m3}, {@code m4}). The edges in
+ * its readability graph are:
The edges in the conceptual service-use graph are:
+ *
{@code
+ * m1 --> m2 (meaning m1 uses a service that is provided by m2)
+ * m1 --> m3
+ * }
+ *

Setting the {@code accessible} flag in a reflected object
- * permits sophisticated applications with sufficient privilege, such
- * as Java Object Serialization or other persistence mechanisms, to
- * manipulate objects in a manner that would normally be prohibited.
- *
- *
By default, a reflected object is not accessible.
+ *
Java language access control prevents use of private members outside
+ * their class; package access members outside their package; protected members
+ * outside their package or subclasses; and public members outside their
+ * module unless they are declared in an {@link Module#isExported(String,Module)
+ * exported} package and the user {@link Module#canRead reads} their module. By
+ * default, Java language access control is enforced (with one variation) when
+ * {@code Field}s, {@code Method}s, or {@code Constructor}s are used to get or
+ * set fields, to invoke methods, or to create and initialize new instances of
+ * classes, respectively. Every reflected object checks that the code using it
+ * is in an appropriate class, package, or module.
The one variation from Java language access control is that the checks
+ * by reflected objects assume readability. That is, the module containing
+ * the use of a reflected object is assumed to read the module in which
+ * the underlying field, method, or constructor is declared.
*
+ *
Whether the checks for Java language access control can be suppressed
+ * (and thus, whether access can be enabled) depends on whether the reflected
+ * object corresponds to a member in an exported or open package
+ * (see {@link #setAccessible(boolean)}).
