      Returns the number of intersections between this curve and a line segment defined by the two specified points.

      This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. 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
      Parameters:
      aP1 - the first point of the line segment
      aP2 - the second point of the line segment
      Returns:
      the number of intersections between the curve and the line segment
