public abstract class DelegateSupport

extends java.lang.Object

implements java.io.Serializable

Base class for all client-side delegate classes. Client-side delegate classes provide an empty implementation of the appropriate delegate interface. The classes are advised using JBoss AOP to provide the client side advice stack. The methods in the delegate class will never actually be invoked since they will either be handled in the advice stack or invoked on the server before reaching the delegate. The delegates are created on the server and serialized back to the client. When they arrive on the client, the init() method is called which causes the advices to be bound to the advised class.
