      toString in class Object

    • isSymmetric

      public boolean isSymmetric()
      Returns true of the padding is identical on all sides (x1 == x2 == y1 == y2).
      Returns:

    • isEmpty

      Returns true of the padding is zero.
      Returns:

    • add

      public Padding add(Padding padding)
      Add this padding to another. This padding is unchanged.
      Parameters:
      padding -
      Returns:
      a Padding where the padding on all sides is the sum of the corresponding padding of both objects.

    • subtract

      public Padding subtract(Padding padding)
      Add another padding from this one. This padding is unchanged.
      Parameters:
      padding -
      Returns:
      a Padding where the padding on all sides is result of subtracting another padding from this one. Note that all values from the padding being subtracted must be ≤ the corresponding values of this padding.
