37/**
38 * The PortableServer::Current interface, derived from
39 * CORBA::Current, provides method implementations with
40 * access to the identity of the object on which the
41 * method was invoked. The Current interface is provided
42 * to support servants that implement multiple objects,
43 * but can be used within the context of POA-dispatched
44 * method invocations on any servant. To provide location
45 * transparency, ORBs are required to support use of
46 * Current in the context of both locally and remotely
47 * invoked operations. An instance of Current can be
48 * obtained by the application by issuing the
49 * CORBA::ORB::resolve_initial_references("POACurrent")
50 * operation. Thereafter, it can be used within the
51 * context of a method dispatched by the POA to obtain
52 * the POA and ObjectId that identify the object on
53 * which that operation was invoked.
