java.lang.Object

com.goldencode.p2j.net.InvocationStub

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

Direct Known Subclasses:

LocalRedirector, LocalStaticRedirector, RemoteObject.RemoteAccess

public abstract class InvocationStub
extends java.lang.Object
implements java.lang.reflect.InvocationHandler

Provides common logic for dynamic proxy implementations. Subclasses only need to implement the invokeCore(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]) method.
