    • Method Detail

      • toString

        public java.lang.String toString()
        Returns a string representing the object.
        Overrides:

        Returns the rotation factor, which is -1.0 for CLOCKWISE and 1.0 for ANTICLOCKWISE.
        Returns:
        the rotation factor.

      • equals

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

                              throws java.io.ObjectStreamException
        Ensures that serialization returns the unique instances.
        Returns:
        the object.
        Throws:
        java.io.ObjectStreamException - if there is a problem.
