public static interface VideoStream.NewFrameListener

The VideoStream::NewFrameListener interface is provided to allow the implementation of event driven frame reading. To use it, create a class that inherits from it and implement override the onNewFrame() method. Then, register your created class with an active VideoStream using the VideoStream.addNewFrameListener(org.openni.VideoStream.NewFrameListener) function. Once this is done, the event handler function you implemented will be called whenever a new frame becomes available. You may call VideoStream.readFrame() from within the event handler.
