public synchronized void removeNotificationListener(NotificationListener listener, NotificationFilter filter, Object handback) throws ListenerNotFoundException

Implements javax.management.NotificationEmitter.removeNotificationListener.

Doc from javax.management.NotificationEmitter.removeNotificationListener.

Removes a listener from this MBean. The MBean must have a listener that exactly matches the given listener, filter, and handback parameters. If there is more than one such listener, only one is removed.

The filter and handback parameters may be null if and only if they are null in a listener to be removed.

Parameters
listener:NotificationListener

A listener that was previously added to this MBean.

filter:NotificationFilter

The filter that was specified when the listener was added.

handback:Object

The handback that was specified when the listener was added.

Exceptions

public synchronized void removeNotificationListener(NotificationListener listener) throws ListenerNotFoundException

Implements javax.management.NotificationBroadcaster.removeNotificationListener.

Doc from javax.management.NotificationBroadcaster.removeNotificationListener.

Removes a listener from this MBean. If the listener has been registered with different handback objects or notification filters, all entries corresponding to the listener will be removed.

Parameters
listener:NotificationListener

A listener that was previously added to this MBean.

Exceptions
ListenerNotFoundException:
The listener is not registered with the MBean.
sendNotificationback to summary
public void sendNotification(Notification notification)

Enables the MBean server to send a notification. If the passed notification has a sequence number lesser or equal to 0, then replace it with the delegate's own sequence number.

Parameters
