      Description copied from interface: ILcdCurve
      Returns the number of intersections between this curve and a line segment defined by the two specified points.

By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.

      Specified by:
      getLineSegmentIntersectionCount in interface ILcdCurve
