29 * This class represents the string form of the address of
30 * a communications end-point.
31 * It consists of a type that describes the communication mechanism
32 * and a string contents specific to that communication mechanism.
33 * The format and interpretation of
34 * the address type and the contents of the address are based on
35 * the agreement of three parties: the client that uses the address,
36 * the object/server that can be reached using the address, and the
37 * administrator or program that creates the address.
38 *
39 * <p> An example of a string reference address is a host name.
40 * Another example of a string reference address is a URL.
41 *
42 * <p> A string reference address is immutable:
43 * once created, it cannot be changed. Multithreaded access to
44 * a single StringRefAddr need not be synchronized.
