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.
void	nodeJoined(ClusterNode node) A node has joined the cluster
void	nodeLeft(ClusterNode node) A node has left the cluster

Method Detail

nodeJoined

void nodeJoined(ClusterNode node)

A node has joined the cluster

Parameters:

node - The joining node

nodeLeft

void nodeLeft(ClusterNode node)

A node has left the cluster

Parameters:

node - The departing node

clusterOnline

void clusterOnline(ClusterNode node)

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

Parameters:

node - The current node

clusterOffline

void clusterOffline(ClusterNode node)

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

Parameters:

node - The current node

clusterRejoined

void clusterRejoined(ClusterNode oldNode,
                     ClusterNode newNode)

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

Parameters:
