Class PenStrokeListener

java.lang.Object
  edu.stanford.hci.r3.pen.streaming.listeners.PenStrokeListener

All Implemented Interfaces:

PenListener

public abstract class PenStrokeListener
extends java.lang.Object
implements PenListener

This lives in the streaming.listeners package because you cannot use this listener directly if your pattern spans multiple sheets. This listener stores information in raw Streaming PenSamples, so you will have to do the calculations yourself... This class is definitely for experts only!

The class also doesn't do any filtering, so if the pen is bad, you will get lots of PenDown/PenUps in rapid succession.
