public interface StrokeRecognizer

A recognizer responds to changes in strokes and returns recognition sets (interpretations of the stroke or of some or all of the scene) based on these changes.

Method Summary

Modifier and Type	Method and Description
RecognitionSet	strokeCompleted(TimedStroke s) Invoked when a stroke is completed.
RecognitionSet	strokeModified(TimedStroke s) Invoked when a stroke has been modified, for example, points have been added to the stroke.
RecognitionSet	strokeStarted(TimedStroke s) Invoked when a stroke starts.

Method Detail

strokeStarted

RecognitionSet strokeStarted(TimedStroke s)

Invoked when a stroke starts. This occurs when the mouse down event has been detected.

strokeModified

RecognitionSet strokeModified(TimedStroke s)

Invoked when a stroke has been modified, for example, points have been added to the stroke. It is probably safe to assume that this will be called every time a point is added to a stroke.

strokeCompleted

RecognitionSet strokeCompleted(TimedStroke s)

Invoked when a stroke is completed. This occurs when the mouse up event has been detected.
