Class DeviceAnnouncementAdapter

java.lang.Object

org.deepsymmetry.beatlink.DeviceAnnouncementAdapter

All Implemented Interfaces:

DeviceAnnouncementListener

public abstract class DeviceAnnouncementAdapter
extends Object
implements DeviceAnnouncementListener

An abstract adapter class for receiving device announcements. The methods in this class are empty; it exists as a convenience for creating listener objects.

Extend this class to create a DeviceAnnouncementListener and override only the methods for events that you care about. If you plan to implement all the methods in the interface, you might as well implement DeviceAnnouncementListener directly.

Create a listener object using your extended class and then register it using DeviceFinder.addDeviceAnnouncementListener(DeviceAnnouncementListener). Whenever a new device is found, or a device disappears from the network, the relevant method in the listener object is invoked, and the DeviceAnnouncement is passed to it.

deviceLost

public void deviceLost(DeviceAnnouncement announcement)

Description copied from interface: DeviceAnnouncementListener

Invoked when a DJ Link device is no longer seen on the network.
