Class MulticastingInvoker

com.thoughtworks.proxy.toys.multicast.MulticastingInvoker

All Implemented Interfaces:

Invoker, java.io.Serializable

public class MulticastingInvoker
extends java.lang.Object
implements Invoker

A Invoker implementation that multicasts calls to multiple targets. Proxies generated by this class will forward all method invocations to an array of underlying objects. The behaviour is recursive, so return values will also be multicasting objects.
