    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.
