All Implemented Interfaces:

Cloneable, JPTConstants, Serializable, Shape, Stringable, SwingConstants

public final class XLine2D

extends Line2D.Double

implements Serializable, Stringable, JPTConstants

Class XLine2D extends Line2D.Double in order to provide a much shorter name that does not explicitly refer to an inner class and to support Stringable.
