Class LinearGradientPaintKey

  org.jfree.graphics2d.LinearGradientPaintKey

public class LinearGradientPaintKey
extends Object

A wrapper for a LinearGradientPaint that can be used as the key for a Map (including a HashMap). This class is used internally by SVGGraphics2D to track and re-use gradient definitions. LinearGradientPaint itself does not implement the equals() and hashCode() methods, so it doesn't make a good key for a Map.

Since:

1.9
