/**
 * This class represents the string form of the address of
 * a communications end-point. 
 * It consists of a type that describes the communication mechanism
 * and a string contents specific to that communication mechanism. 
 * The format and interpretation of
 * the address type and the contents of the address 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. 
 *
 * <p> An example of a string reference address is a host name. 
 * Another example of a string reference address is a URL. 
 *
 * <p> A string reference address is immutable:
 * once created, it cannot be changed.   Multithreaded access to
 * a single StringRefAddr need not be synchronized.
