Delegate

Synopsis

A Delegate is responsible for implementing all of the methods on org.omg.CORBA.Object. The Object contains a Delegate and forwards its methods to it. This allows for portability between ORB implementations, since an Object obtained from one ORB can contain a Delegate specific to that ORB, but the Object can still be used within another ORB.
