Method Detail

register

public void register(IMigrationListener listener)

unregister

public void unregister(IMigrationListener listener)

onJoin

public void onJoin(java.net.InetAddress endpoint,
                   EndpointState epState)

Description copied from interface: IEndpointStateChangeSubscriber

Use to inform interested parties about the change in the state for specified endpoint

Specified by:

onJoin in interface IEndpointStateChangeSubscriber

Parameters:

endpoint - endpoint for which the state change occurred.

epState - state that actually changed for the above endpoint.

onChange

public void onChange(java.net.InetAddress endpoint,
                     ApplicationState state,
                     VersionedValue value)

Specified by:

onChange in interface IEndpointStateChangeSubscriber

onAlive

public void onAlive(java.net.InetAddress endpoint,
                    EndpointState state)

Specified by:

onAlive in interface IEndpointStateChangeSubscriber

onDead

public void onDead(java.net.InetAddress endpoint,
                   EndpointState state)

Specified by:

onDead in interface IEndpointStateChangeSubscriber

onRestart

public void onRestart(java.net.InetAddress endpoint,
                      EndpointState state)

Description copied from interface: IEndpointStateChangeSubscriber

Called whenever a node is restarted. Note that there is no guarantee when that happens that the node was previously marked down. It will have only if state.isAlive() == false as state is from before the restarted node is marked up.

Specified by:

onRestart in interface IEndpointStateChangeSubscriber

onRemove

public void onRemove(java.net.InetAddress endpoint)

Specified by:

onRemove in interface IEndpointStateChangeSubscriber
