  • getNotificationInfo

  Returns an array indicating, for each notification this MBean may send, the name of the Java class of the notification and the notification type.

  Parameters:
  listener - The listener object which will handle the notifications emitted by the broadcaster.
  filter - The filter object. If filter is null, no filtering will be performed before handling notifications.
  handback - An opaque object to be sent back to the listener when a notification is emitted. This object cannot be used by the Notification broadcaster object. It should be resent unchanged with the notification to the listener.
  Throws:
  [IllegalArgumentException](../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang") - Listener parameter is null.

  NotificationBroadcaster.removeNotificationListener(javax.management.NotificationListener)

  • 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.
  Specified by:
  [removeNotificationListener](NotificationEmitter.html#removeNotificationListener%28javax.management.NotificationListener,javax.management.NotificationFilter,java.lang.Object%29) in interface [NotificationEmitter](NotificationEmitter.html "interface in javax.management")
  Parameters:
  listener - A listener that was previously added to this MBean.
  filter - The filter that was specified when the listener was added.
  handback - The handback that was specified when the listener was added.
  Throws:
  [ListenerNotFoundException](ListenerNotFoundException.html "class in javax.management") - The listener is not registered with the MBean, or it is not registered with the given filter and handback.

  • 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.
  Specified by:
  [removeNotificationListener](NotificationBroadcaster.html#removeNotificationListener%28javax.management.NotificationListener%29) in interface [NotificationBroadcaster](NotificationBroadcaster.html "interface in javax.management")
  Parameters:
  listener - A listener that was previously added to this MBean.
  Throws:
  [ListenerNotFoundException](ListenerNotFoundException.html "class in javax.management") - The listener is not registered with the MBean.

  NotificationBroadcaster.addNotificationListener(javax.management.NotificationListener, javax.management.NotificationFilter, java.lang.Object), NotificationEmitter.removeNotificationListener(javax.management.NotificationListener, javax.management.NotificationFilter, java.lang.Object)

  • sendNotification

  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:
  notification - The notification to send.
