getInstance

public static ExtendedMemoryMXBeanImpl getInstance()

addNotificationListener

public void addNotificationListener(NotificationListener listener,
 NotificationFilter filter,
 Object handback)
                             throws IllegalArgumentException

Adds a listener to this MBean.

Specified by:

addNotificationListener in interface NotificationBroadcaster

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)

startNotificationThread

protected void startNotificationThread()

Ensure the notification thread is running.

Overrides:

startNotificationThread in class com.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 interface NotificationBroadcaster

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)

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, 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 in interface NotificationEmitter

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.

sendNotification

public final void sendNotification(Notification notification)

Send notifications to registered listeners.

Parameters:

notification - a notification to be sent
