// = DESCRIPTION
// Lightweight encapsulation of addressing information for a
// single acceptor endpoint. In other words, Endpoint represents
// a single point of contact for the server, and is the smallest
// unit of addressing information necessary for a client to connect
// to a server.
// A Profile contains one or more Endpoints, i.e., knows of
// one or more ways to contact server(s).

// Return a string representation for the address. Returns

// provide a general interface to the underlying address object's
// addr_to_string method. This allows the protocol implementor to
// select the appropriate string format.

// This method is used when a connection has been reset, requiring
// the hint to be cleaned up and reset to NULL.
//virtual TAO_Endpoint *duplicate (void) = 0;
// This method returns a copy of the corresponding endpoints by
// allocation memory
