org.jgroups.demos.RelayDemoRpc

All Implemented Interfaces:

MembershipListener, MessageListener, Receiver, StateListener

public class RelayDemoRpc
extends ReceiverAdapter

Demos RELAY. Create 2 *separate* clusters with RELAY as top protocol. Each RELAY has bridge_props="tcp.xml" (tcp.xml needs to be present). Then start 2 instances in the first cluster and 2 instances in the second cluster. They should find each other, and typing in a window should send the text to everyone, plus we should get 4 responses.

viewAccepted

public void viewAccepted(View new_view)

Description copied from interface: MembershipListener

Called when a change in membership has occurred. No long running actions, sending of messages or anything that could block should be done in this callback. If some long running action needs to be performed, it should be done in a separate thread.

Note that on reception of the first view (a new member just joined), the channel will not yet be in the connected state. This only happens when JChannel.connect(String) returns.

Specified by:

viewAccepted in interface MembershipListener
