Public Methods

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

Adds a listener to this MBean.

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

public String getImplementationName ()

Returns the JMX implementation name (the name of this product).

Returns
  • the implementation name.

public String getImplementationVendor ()

Returns the JMX implementation vendor (the vendor of this product).

Returns
  • the implementation vendor.

public String getImplementationVersion ()

Returns the JMX implementation version (the version of this product).

Returns
  • the implementation version.

public synchronized String getMBeanServerId ()

Returns the MBean server agent identity.

Returns
  • the identity.

public MBeanNotificationInfo[] 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.

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.

Returns
  • the array of possible notifications.

public String getSpecificationName ()

Returns the full name of the JMX specification implemented by this product.

Returns
  • the specification name.

public String getSpecificationVendor ()

Returns the vendor of the JMX specification implemented by this product.

Returns
  • the specification vendor.

public String getSpecificationVersion ()

Returns the version of the JMX specification implemented by this product.

Returns
  • the specification version.

public synchronized void removeNotificationListener (NotificationListener listener)

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 A listener that was previously added to this MBean.
Throws
ListenerNotFoundException

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

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 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

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.
