addNotificationListener
public void addNotificationListener(NotificationListener listener, NotificationFilter filter, Object handback) throws IllegalArgumentException 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:
-
startNotificationThread
protected void startNotificationThread()Ensure the notification thread is running.- Overrides:
startNotificationThread
in classcom.ibm.java.lang.management.internal.MemoryMXBeanImpl
-
removeNotificationListener
public final void removeNotificationListener(NotificationListener listener) throws ListenerNotFoundException 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:
-
removeNotificationListener
public final void removeNotificationListener(NotificationListener listener, NotificationFilter filter, Object handback) throws ListenerNotFoundException 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.
