Detailed Description

The OpenNI::DeviceStateChangedListener class 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() 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() function is also provided, if you want to have your class stop listening to these events for any reason.

		OniDeviceState	state,
		void *	pCookie
	)		`[inline, static, private]`

virtual void openni::OpenNI::DeviceStateChangedListener::onDeviceStateChanged	(	const DeviceInfo *	,
		DeviceState
	)		`[pure virtual]`

Callback function for the onDeviceStateChanged event. This function will be called whenever this event occurs. When this happens, a pointer to a DeviceInfo object for the affected device will be supplied, as well as the new DeviceState value of that device.

Implemented in astra_wrapper::AstraDeviceListener.
