Class DoubleStroke

java.lang.Object
  org.jhotdraw.geom.DoubleStroke

All Implemented Interfaces:

java.awt.Stroke

Direct Known Subclasses:

GrowStroke

public class DoubleStroke
extends java.lang.Object
implements java.awt.Stroke

Draws a double stroke (an outline of an outline). The inner width of a DoubleStroke defines the distance between the two outlines being drawn. The outline width of a DoubleStroke defines the thickness of the outline.
