    • Rotation

      private Rotation(String name, double factor)
      Private constructor.
      Parameters:
      name - the name.
      factor - the rotation factor.

  • Method Details

      the string (never null).

    • getFactor

      public double getFactor()
      Returns the rotation factor, which is -1.0 for CLOCKWISE and 1.0 for ANTICLOCKWISE.
      Returns:
      the rotation factor.

    • equals

      public boolean equals(Object o)
      Compares this object for equality with an other object. Implementation note: This simply compares the factor instead of the name.
