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