        Returns:
        a copy of the stored point.
      • getPointRef

        public double[] getPointRef()
        Gets a reference to the point.
        Returns:
        a reference to the internal array storing the point.
      • writeReplace

        private java.lang.Object writeReplace()
        Replace the instance with a data transfer object for serialization.
        Returns:
        data transfer object that will be serialized
