  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.
