+ * A BinaryRefAddr consists of a type that describes the communication mechanism + * and an opaque buffer containing the address description + * specific to that communication mechanism. The format and interpretation of + * the address type and the contents of the opaque buffer are based on + * the agreement of three parties: the client that uses the address, + * the object/server that can be reached using the address, + * and the administrator or program that creates the address. + *

+ * An example of a binary reference address is an BER X.500 presentation address. + * Another example of a binary reference address is a serialized form of + * a service's object handle. + *

+ * A binary reference address is immutable in the sense that its fields + * once created, cannot be replaced. However, it is possible to access + * the byte array used to hold the opaque buffer. Programs are strongly + * recommended against changing this byte array. Changes to this + * byte array need to be explicitly synchronized. + * + * @author Rosanna Lee + * @author Scott Seligman + * + * @see RefAddr + * @see StringRefAddr + * @since 1.3 + */ + + /* + * The serialized form of a BinaryRefAddr object consists of its type + * name String and a byte array containing its "contents". + */ + +public class BinaryRefAddr extends RefAddr { + /** + * Contains the bytes of the address. + * This field is initialized by the constructor and returned + * using getAddressBytes() and getAddressContents(). + * @serial + */ + private byte[] buf = null; + + /** + * Constructs a new instance of BinaryRefAddr using its address type and a byte + * array for contents. + * + * @param addrType A non-null string describing the type of the address. + * @param src The non-null contents of the address as a byte array. + * The contents of src is copied into the new BinaryRefAddr. + */ + public BinaryRefAddr(String addrType, byte[] src) { + this(addrType, src, 0, src.length); + } + + /** + * Constructs a new instance of BinaryRefAddr using its address type and + * a region of a byte array for contents. + * + * @param addrType A non-null string describing the type of the address. + * @param src The non-null contents of the address as a byte array. + * The contents of src is copied into the new BinaryRefAddr. + * @param offset The starting index in src to get the bytes. + * {@code 0 <= offset <= src.length}. + * @param count The number of bytes to extract from src. + * {@code 0 <= count <= src.length-offset}. + */ + public BinaryRefAddr(String addrType, byte[] src, int offset, int count) { + super(addrType); + buf = new byte[count]; + System.arraycopy(src, offset, buf, 0, count); + } + + /** + * Retrieves the contents of this address as an Object. + * The result is a byte array. + * Changes to this array will affect this BinaryRefAddr's contents. + * Programs are recommended against changing this array's contents + * and to lock the buffer if they need to change it. + * + * @return The non-null buffer containing this address's contents. + */ + public Object getContent() { + return buf; + } + + + /** + * Determines whether obj is equal to this address.
