java.lang.Object
  java.awt.geom.Point2D
      java.awt.geom.Point2D.Double
          ui.recognizer.DataCoordinate

All Implemented Interfaces:

Cloneable, Comparable

public class DataCoordinate
extends Point2D.Double
implements Comparable

A class which can represent a data coordinate : an object containing an absissa (x) and ordinate (y) value and which can be printed and ordered appropriately. The units are in double precision because the data can represent any real number when calibrated. When sorted, data coordinates are ordered by their x coordinate. This class is compatible with java.awt.Point2D.
