Package net.sf.ehcache

Class CacheClusterStateStatisticsListener

java.lang.Object

net.sf.ehcache.CacheClusterStateStatisticsListener

All Implemented Interfaces:

ClusterTopologyListener

public class CacheClusterStateStatisticsListener
extends java.lang.Object
implements ClusterTopologyListener

A listener to capture statistics relating to cluster events regarding this node. This should really be a single listener, at the cache manager level, with CacheManager statistics. But we don't have that concept at the moment. Sad face.

void	clusterOffline(ClusterNode node)	This node has lost contact (possibly temporarily) with the cluster and cannot execute clustered operations
void	clusterOnline(ClusterNode node)	This node has established contact with the cluster and can execute clustered operations.
void	clusterRejoined(ClusterNode oldNode, ClusterNode newNode)	This node lost contact and rejoined the cluster again.
long	getMostRecentRejoinTimeStampMS()	Gets the last rejoin time stamp nanos.
void	nodeJoined(ClusterNode node)	A node has joined the cluster

Method Detail

nodeLeft

public void nodeLeft(ClusterNode node)

Description copied from interface: ClusterTopologyListener

A node has left the cluster

Specified by:

nodeLeft in interface ClusterTopologyListener

Parameters:

node - The departing node

nodeJoined

public void nodeJoined(ClusterNode node)

Description copied from interface: ClusterTopologyListener

A node has joined the cluster

Specified by:

nodeJoined in interface ClusterTopologyListener

Parameters:

node - The joining node

clusterRejoined

public void clusterRejoined(ClusterNode oldNode,
                            ClusterNode newNode)

Description copied from interface: ClusterTopologyListener

This node lost contact and rejoined the cluster again.

This event is only fired in the node which rejoined and not to all the connected nodes

Specified by:

clusterRejoined in interface ClusterTopologyListener

Parameters:

oldNode - The old node which got disconnected

newNode - The new node after rejoin

clusterOnline

public void clusterOnline(ClusterNode node)

Description copied from interface: ClusterTopologyListener

This node has established contact with the cluster and can execute clustered operations.

Specified by:

clusterOnline in interface ClusterTopologyListener

Parameters:

node - The current node

clusterOffline

public void clusterOffline(ClusterNode node)

Description copied from interface: ClusterTopologyListener

This node has lost contact (possibly temporarily) with the cluster and cannot execute clustered operations

Specified by:

clusterOffline in interface ClusterTopologyListener

Parameters:

node - The current node

getMostRecentRejoinTimeStampMS

public long getMostRecentRejoinTimeStampMS()

Gets the last rejoin time stamp nanos.

Returns:

the last rejoin time stamp nanos
