All Implemented Interfaces:

java.io.Serializable

public class TunnelInvocationHandler

extends java.lang.Object

implements java.io.Serializable

Implementation of InvocationHandler used by DynamicProxyStub. The class implements handler for remote interface. All methods of remote interface are delegated to the handler. The class supports packaging requests with DataStack. It also recognizes Callbacks and creates for them proxies stubs. The class is used by client and created by Tunneling server.

The implementation of InvocationHandler Processes a method invocation on a proxy instance and returns the result. The method implements virtual method for Object class of the stub.

Parameters:

proxy - the proxy instance that the method was invoked on

method - the Method instance corresponding to the interface method invoked on the proxy

args - an array of objects containing the values of the arguments passed in the method
