- ## Method Details

  - ### handleNotification

    void handleNotification​(Notification notification, Object handback)
    Invoked when a JMX notification occurs. The implementation of this method should return as soon as possible, to avoid blocking its notification broadcaster.
    Parameters:
      `notification` - The notification.
      `handback` - An opaque object which helps the listener to associate information regarding the MBean emitter. This object is passed to the addNotificationListener call and resent, without modification, to the listener.
