BroadcastDispatcher

public class BroadcastDispatcher extends Object implements Dispatchable
Broadcast a single dispatch into multiple other dispatchables.

Every time {@link #dispatch} is invoked, all the broadcast targets will see the same dispatch as well. The first target's return value is returned.

This enables a single listener to be converted into a multi-listener.
