serverAdded

public void serverAdded(ServerName serverName)

Description copied from interface: ServerListener

The server has joined the cluster.

Specified by:

serverAdded in interface ServerListener

Parameters:

serverName - The remote servers name.

serverRemoved

public void serverRemoved(ServerName serverName)

Description copied from interface: ServerListener

The server was removed from the cluster.

Specified by:

serverRemoved in interface ServerListener

operations - Remote procedures which are dispatched to the given server

resolver - Used to dispatch remote procedures to given server.
