  com.thoughtworks.proxy.toys.multicast.MulticastingInvoker<T>

All Implemented Interfaces:

Invoker, Serializable

public class MulticastingInvoker<T>
extends 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 behavior is recursive, so return values will also be multicasting objects.
