Interface LineDecoration

All Superinterfaces:

java.lang.Cloneable, java.io.Serializable

All Known Implementing Classes:

AbstractLineDecoration, ArrowTip, GeneralPathTip

public interface LineDecoration
extends java.lang.Cloneable, java.io.Serializable

Decorate the start or end Point2D.Double of a line or poly line figure. LineDecoration is the base class for the different line decorations.

Method Summary

void	draw(java.awt.Graphics2D g, Figure f, java.awt.geom.Point2D.Double p1, java.awt.geom.Point2D.Double p2) Draws the decoration in the direction specified by the two Points.
double	getDecorationRadius(Figure f) Returns the radius of the decorator.
java.awt.geom.Rectangle2D.Double	getDrawBounds(Figure f, java.awt.geom.Point2D.Double p1, java.awt.geom.Point2D.Double p2) Returns the drawing bounds of the decorator.

Method Detail

draw

void draw(java.awt.Graphics2D g,
          Figure f,
          java.awt.geom.Point2D.Double p1,
          java.awt.geom.Point2D.Double p2)

Draws the decoration in the direction specified by the two Points.

getDecorationRadius

double getDecorationRadius(Figure f)

Returns the radius of the decorator. This is used to crop the end of the line, to prevent it from being drawn it over the decorator.

getDrawBounds

java.awt.geom.Rectangle2D.Double getDrawBounds(Figure f,
                                               java.awt.geom.Point2D.Double p1,
                                               java.awt.geom.Point2D.Double p2)

Returns the drawing bounds of the decorator.
