Method Detail

handleClusterPacket

void handleClusterPacket(Element packet)

Method handles cluster packet received from cluster connection.

Parameters:

packet - which should be handled

nodeConnected

void nodeConnected(String addr)

Method is called on cluster node connection event. This is a notification to the component that a new cluster node has connected.

Parameters:

addr - is a hostname of a cluster node generating the event.

nodeDisconnected

void nodeDisconnected(String addr)

Method is called on cluster node disconnection event. This is a notification to the component that there was network connection lost to one of the cluster nodes.

Parameters:

addr - is a hostname of a cluster node generating the event.

removeCommandListener

void removeCommandListener(CommandListener listener)

sendToNodes

void sendToNodes(String command,
                 Map<String,String> data,
