Class ArrowTip

java.lang.Object
  org.jhotdraw.draw.decoration.AbstractLineDecoration
      org.jhotdraw.draw.decoration.ArrowTip

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, LineDecoration, DOMStorable

public class ArrowTip
extends AbstractLineDecoration
implements DOMStorable

A LineDecoration which can draws an arrow tip.

The shape of the arrow can be controlled with three parameters:

• angle - the angle in radians at which the two legs of the arrow meet.
• outer radius - the length of the two legs of the arrow.
• inner radius - the distance from the tip of the arrow to the point where its end meets the line.
