Interface RemoteEventProducer

All Superinterfaces:

EventProducer

All Known Subinterfaces:

Room, Server

public interface RemoteEventProducer
extends EventProducer

A RemoteEventProducer can dispatch events that are re-dispatched by the equivalent objects across the cluster. If a ClusterRole.MASTER room dispatches a remote event it is re-dispatched by each ClusterRole.SLAVE room across the cluster. If a ClusterRole.SLAVE room dispatches a remote event it is re-dispatched by the ClusterRole.MASTER room. If the server dispatches a remote event it is re-dispatched by each server on the cluster.
