public abstract class Proxy
extends java.lang.Object

The superclass for all proxies. The proxy synchronizes access to the source and the target of invocations on itself. Users can synchronize on the proxy in order to perform an atomic set or get on both, the target and the source of the proxy. The methods that execute an invocation are deliberately unsynchronized. The proxy offers methods to create default invocations for remote method calls. At the present time the proxy enables the transfer of asynchronous, synchronous and deferred synchronous method calls. Note that all methods of the proxy have a prefix called "proxy". Thus, user code should not use base as a prefix for methods in order to avoid naming conflicts with user interfaces.
