Examples of javax.management.NotificationBroadcasterSupport$FilterHandbackPair

javax.management.NotificationBroadcasterSupport
Provides an implementation of NotificationEmitter interface. This can be used as the super class of an MBean that sends notifications. It is not specified whether the notification dispatch model is synchronous or asynchronous. That is, when a thread calls sendNotification, the NotificationListener.handleNotification method of each listener may be called within that thread (a synchronous model) or within some other thread (an asynchronous model). Applications should not depend on notification dispatch being synchronous or being asynchronous. Thus:
- Applications should not assume a synchronous model. When the sendNotification method returns, it is not guaranteed that every listener's handleNotification method has been called. It is not guaranteed either that a listener will see notifications in the same order as they were generated. Listeners that depend on order should use the sequence number of notifications to determine their order (see Notification.getSequenceNumber()).
- Applications should not assume an asynchronous model. If the actions performed by a listener are potentially slow, the listener should arrange for them to be performed in another thread, to avoid holding up other listeners and the caller of sendNotification.
