Method Detail

• hashCodeForPaint

  public static int hashCodeForPaint(Paint p)

  Returns a hash code for a Paint instance. If p is null, this method returns zero.

  Parameters:

  p - the paint (null permitted).

  Returns:

  The hash code.

• hashCodeForDoubleArray

  Returns a hash code for a double[] instance. If the array is null, this method returns zero.

  Parameters:

  a - the array (null permitted).

  Returns:

  The hash code.

• hashCode

  public static int hashCode(int pre,
                             boolean b)

  Returns a hash value based on a seed value and the value of a boolean primitive.

  Parameters:

  pre - the seed value.

  b - the boolean value.

  Returns:

  A hash value.

  Since:

  1.0.7

• hashCode

  public static int hashCode(int pre,
                             org.jfree.util.BooleanList list)

  Computes a hash code for a BooleanList. In the latest version of JCommon, the BooleanList class should implement the hashCode() method correctly, but we compute it here anyway so that we can work with older versions of JCommon (back to 1.0.0).

  Parameters:

  pre - the seed value.

  list - the list (null permitted).

  Returns:

  The hash code.

  Since:

  1.0.9

• hashCode

  public static int hashCode(int pre,
                             org.jfree.util.PaintList list)

  Computes a hash code for a PaintList. In the latest version of JCommon, the PaintList class should implement the hashCode() method correctly, but we compute it here anyway so that we can work with older versions of JCommon (back to 1.0.0).

  Parameters:

  pre - the seed value.

  list - the list (null permitted).

  Returns:

  The hash code.

• hashCode

  public static int hashCode(int pre,
                             org.jfree.util.StrokeList list)

  Computes a hash code for a StrokeList. In the latest version of JCommon, the StrokeList class should implement the hashCode() method correctly, but we compute it here anyway so that we can work with older versions of JCommon (back to 1.0.0).

  Parameters:

  pre - the seed value.

  list - the list (null permitted).

  Returns:

  The hash code.
