Class GradientPaintKey


  • public final class GradientPaintKey
    extends java.lang.Object
    A wrapper for a GradientPaint that can be used as the key for a HashMap. This class is used internally by PDFGraphics2D to track and re-use gradient definitions. GradientPaint itself does not implement the equals() and hashCode() methods, so it doesn't make a good key for a Map.
