## Class LinearGradientPaintKey

- java.lang.Object
- - org.jfree.graphics2d.LinearGradientPaintKey

-     public class LinearGradientPaintKey
      extends java.lang.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:
