Class BroadcastMessage

java.lang.Object
  org.atmosphere.plugin.jgroups.BroadcastMessage

All Implemented Interfaces:

Serializable

public class BroadcastMessage
extends Object
implements Serializable

Container for holding the true message when broadcasting between cluster nodes. It provides knowledge of 'who' sent the message, using the generated globally unique Id, clusterChannelId instead of a JChannel host. This is because the JGroupsChannel the sent it will get the message too and needs to know to discard it. The standard JGroupsFilter implementation uses the JChannel address, Example: org.atmosphere.plugins.jgroups.JGroupsFilter.receive() says... if (message.getSrc() != jchannel.getLocalAddress()) { This is not good enough if multiple JChannels are started on a single host, so each JGroupsChannel instance should have a globally unique Id instead and set that value into each BroadcastMessage it sends.
