public class TimedStroke
extends Polyline2D.Float
implements PropertyContainer

TimedStroke is a collection of points taken in the duration of a mouse pressed event and a mouse released event. A TimedStroke object contains basic stroke path information (such as the points and the timestamps in the path) and can be annotated to contain application-specific information, e.g. properties used in the recognition process.
