List of fetchNotifications() Examples

Examples of fetchNotifications()

com.sun.jmx.remote.internal.NotificationBuffer.fetchNotifications()

Fetch notifications that match the given listeners.

The operation only considers notifications with a sequence number at least startSequenceNumber. It will take no longer than timeout, and will return no more than maxNotifications different notifications.

If there are no notifications matching the criteria, the operation will block until one arrives, subject to the timeout.
@param filter an object that will add notifications to a{@code List} if they match the currentlisteners with their filters. @param startSequenceNumber the first sequence number toconsider. @param timeout the maximum time to wait. May be 0 to indicatenot to wait if there are no notifications. @param maxNotifications the maximum number of notifications toreturn. May be 0 to indicate a wait for eligible notifications that will return a usable nextSequenceNumber. The {@link TargetedNotification} array in the returned {@link NotificationResult} may contain more than this number ofelements but will not contain more than this number of different notifications.
mx4j.remote.DefaultRemoteNotificationServerHandler.fetchNotifications()
mx4j.remote.RemoteNotificationServerHandler.fetchNotifications()
Fetches notifications from the notification buffer in order to send them to the client side @throws IOException If this handler has already been closed
