 javax.management.AttributeChangeNotification
| AttributeChangeNotification | | public class AttributeChangeNotification extends javax.management.Notification (Code) | | Provides definitions of the attribute change notifications sent by MBeans.
It's up to the MBean owning the attribute of interest to doCreate and send
attribute change notifications when the attribute change occurs.
So the NotificationBroadcaster interface has to be implemented
by any MBean for which an attribute change is of interest.
Example:
If an MBean called myMbean needs to notify registered listeners
when its attribute:
String myString
is modified, myMbean creates and emits the following notification:
new AttributeChangeNotification(myMbean, sequenceNumber, timeStamp, msg,
"myString", "String", oldValue, newValue);
