getNotificationInfo
public MBeanNotificationInfo[] getNotificationInfo()
Description copied from interface:NotificationBroadcaster
Returns an array indicating, for each notification this MBean may send, the name of the Java class of the notification and the notification type.
It is not illegal for the MBean to send notifications not described in this array. However, some clients of the MBean server may depend on the array being complete for their correct functioning.
- Specified by:
getNotificationInfo
in interfaceNotificationBroadcaster
- Returns:
- the array of possible notifications.
-
addNotificationListener
public void addNotificationListener(NotificationListener listener, NotificationFilter filter, Object handback) throws IllegalArgumentException
Description copied from interface:NotificationBroadcaster
Adds a listener to this MBean.- Specified by:
addNotificationListener
in interfaceNotificationBroadcaster
- 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
- Listener parameter is null.- See Also:
NotificationBroadcaster.removeNotificationListener(javax.management.NotificationListener)
-
removeNotificationListener
public void removeNotificationListener(NotificationListener listener, NotificationFilter filter, Object handback) throws ListenerNotFoundException
Description copied from interface:NotificationEmitter
Removes a listener from this MBean. The MBean must have a listener that exactly matches the given
listener
,filter
, andhandback
parameters. If there is more than one such listener, only one is removed.The
filter
andhandback
parameters may be null if and only if they are null in a listener to be removed.- Specified by:
removeNotificationListener
in interfaceNotificationEmitter
- 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
- The listener is not registered with the MBean, or it is not registered with the given filter and handback.
-
removeNotificationListener
public void removeNotificationListener(NotificationListener listener) throws ListenerNotFoundException
Description copied from interface:NotificationBroadcaster
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
in interfaceNotificationBroadcaster
- Parameters:
listener
- A listener that was previously added to this MBean.- Throws:
ListenerNotFoundException
- The listener is not registered with the MBean.- See Also:
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:
