Class BezierPath.Node

java.lang.Object
  org.jhotdraw.geom.BezierPath.Node

All Implemented Interfaces:

java.lang.Cloneable

Enclosing class:

BezierPath

public static class BezierPath.Node
extends java.lang.Object
implements java.lang.Cloneable

Defines a vertex (node) of the bezier path.

A vertex consists of three control points: C0, C1 and C2.

• The bezier path always passes through C0.
• C1 is used to control the curve towards C0.
• C2 is used to control the curve going away from C0.

Field Summary

boolean	keepColinear This is a hint for editing tools.
int	mask This mask is used to describe which control points in addition to C0 are in effect.
double[]	x Control point x coordinates.
double[]	y Control point y coordinates.

Field Detail

mask

public int mask

This mask is used to describe which control points in addition to C0 are in effect.

x

public double[] x

Control point x coordinates.

y

public double[] y

Control point y coordinates.

keepColinear

public boolean keepColinear

This is a hint for editing tools. If this is set to true, the editing tools shall keep all control points on the same line.
