All Implemented Interfaces:

IInvocationHandler

Direct Known Subclasses:

ContQueryProcessorSkeleton, LeaseRegistrySkeleton, NFCProcessorSkeleton, SecureSkeleton

public abstract class Skeleton
extends java.lang.Object
implements IInvocationHandler

The superclass for all skeletons. A skeleton keeps a reference to an implementation that can be used to dispatch calls. An invocation that is forwarded by the invocation broker to a skeleton will first be sent to the invoke method. The invoke method then forwards the signature and the parameters of the invocation as well as the current implementation to the dispatch method. The dispatch method should then handle signatures and parameters and return a result object that encapsulates possible return values and exceptions.
