callMethodOnPartition

public void callMethodOnPartition(java.lang.String methodName,
                                  java.lang.Object[] args)
                           throws java.lang.Exception

Description copied from interface: HAServiceMBean (src)

Convenience method for broadcasting a call to all members of a partition.

Specified by:: callMethodOnPartition in interface HAServiceMBean (src)
Overrides:: callMethodOnPartition in class HAServiceMBeanSupport (src)

Parameters:: methodName -; args -
Throws:: java.lang.Exception

startSingleton

public void startSingleton()

Description copied from class: HASingletonSupport (src)

Extending classes should override this method and implement the custom singleton logic. Only one node in the cluster is the active master. If the current node is elected for master, this method is invoked. When another node is elected for master for some reason, the stopSingleton() method is invokded.

When the extending class is a stateful singleton, it will usually use putDistributedState() and getDistributedState() to save in the cluster environment information that will be needed by the next node elected for master should the current master node fail.

Specified by:: startSingleton in interface HASingleton (src)
Overrides:: startSingleton in class HASingletonSupport (src)

See Also:: HASingleton (src)

stopSingleton

public void stopSingleton()

Description copied from class: HASingletonSupport (src)

Extending classes should override this method and implement the custom singleton logic. Only one node in the cluster is the active master. If the current node is master and another node is elected for master, this method is invoked.

Specified by:: stopSingleton in interface HASingleton (src)
Overrides:: stopSingleton in class HASingletonSupport (src)

See Also:: HASingleton (src)

makeThisNodeMaster

protected void makeThisNodeMaster()

Overrides:: makeThisNodeMaster in class HASingletonSupport (src)

sendNotification

public void sendNotification(Notification (src)  notification)

Description copied from interface: HAServiceMBean (src)

Broadcast the notification to the remote listener nodes (if any) and then invoke super.sendNotification() to notify local listeners.

Specified by:: sendNotification in interface HAServiceMBean (src)
Overrides:: sendNotification in class HAServiceMBeanSupport (src)

Parameters:: notification - sent out to local listeners and other nodes. It should be serializable. It is recommended that the source of the notification is an ObjectName of an MBean that is is available on all nodes where the broadcaster MBean is registered.
