Interface OpenNI.DeviceStateChangedListener

Enclosing class:
OpenNI

public static interface OpenNI.DeviceStateChangedListener

The OpenNI::DeviceStateChangedListener interface provides a means of registering for, and responding to when a device's state is changed. onDeviceStateChanged is triggered whenever the state of a connected device is changed. To use this class, you should write a new class that inherits from it, and override the onDeviceStateChanged method. Once you instantiate your class, use the OpenNI.addDeviceStateChangedListener(org.openni.OpenNI.DeviceStateChangedListener) function to add your listener object to OpenNI's list of listeners. Your handler function will then be called whenever the event occurs. A OpenNI.removeDeviceStateChangedListener(org.openni.OpenNI.DeviceStateChangedListener) function is also provided, if you want to have your class stop listening to these events for any reason.
