Package Summary Overview Summary

### class:AttributeChangeNotification [NONE]
All Implemented Interfaces: `Serializable` public class AttributeChangeNotification extends Notification Provides definitions of the attribute change notifications sent by MBeans. It's up to the MBean owning the attribute of interest to create 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);` Since: 1.5 See Also: Serialized Form
