Package Description

Provides the definition of the Timer MBean. A Timer MBean maintains a list of scheduled notifications and, because it is a NotificationBroadcaster, a list of listeners for those notifications. Whenever the time for one of the scheduled notifications is reached, each listener receives the notification. Notifications can be repeated at a fixed interval, and the number of repetitions can be bounded.

A listener for a Timer MBean can itself be an MBean, using the method MBeanServer.addNotificationListener(ObjectName, ObjectName, NotificationFilter, Object). In this way, a management application can create an MBean representing a task, then schedule that task using a Timer MBean.
