Class BezierPath.Node

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

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Enclosing class:

BezierPath

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

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 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.
