java.util.EventObject

org.ocap.hn.DeviceEvent

All Implemented Interfaces:

Serializable

public class DeviceEvent
extends EventObject

Represents a Device Event. There are two types of Device events: one that is generated by the NetManager when a Device is added or removed from the home network. Application may register as a listener to NetManager to receive such events. The other DeviceEvent is generated by the Device itself when its internal state changes. Application should register as a listener with a particular Device for such events. In both scenarios, the Device that was the source of the event is returned.
