Examples of javax.management.AttributeChangeNotification

javax.management.AttributeChangeNotification
This is the mandated object for sending notifications of attribute changes. The MBean may also send other types of notifications. The MBean must implement the {@link javax.management.NotificationBroadcaster} interface to sendthis notification.
The following information is provided in addition to the that provided by {@link javax.management.Notification Notification}. The attribute's {@link #getAttributeName() name}, {@link #getAttributeType() type}, {@link #getOldValue() old value} and{@link #getNewValue() new value}.
The notification type is "jmx.attribute.change", defined in the static string {@link #ATTRIBUTE_CHANGE}. @see javax.management.AttributeChangeNotificationFilter @author Adrian Brock. @version $Revision: 1.3 $
