The UnicastRemoteObject class provides support for point-to-point active object references (invocations, parameters, and results) using TCP streams. <p>Objects that require remote behavior should extend RemoteObject, typically via UnicastRemoteObject. If UnicastRemoteObject is not extended, the implementation class must then assume the responsibility for the correct semantics of the hashCode, equals, and toString methods inherited from the Object class, so that they behave appropriately for remote objects.<P><DL><DT><B>Since: </B><DD>JDK1.1</DD><DT><B>See Also: </B><DD><A
