---Purpose: Empty constructor.
Perform(me: in out; L : Lin from gp;
Prm : Real from Standard;
Tol : Real from Standard;
F : Face from TopoDS)
---Purpose: Perform the intersection between the
-- segment L(0) ... L(Prm) and the Shape <Sh>.
--
-- Only the point with the smallest parameter on the
-- line is returned.
--
-- The Tolerance <Tol> is used to determine if the
-- first point of the segment is near the face. In
-- that case, the parameter of the intersection point
-- on the line can be a negative value (greater than -Tol).

HasAPoint(me)
---Purpose: True is returned if a point has been found.

UParameter(me)
---Purpose: Returns the U parameter of the intersection point
-- on the surface.

---Purpose: Returns the V parameter of the intersection point
-- on the surface.

WParameter(me)
---Purpose: Returns the parameter of the intersection point
-- on the line.

---Purpose: Returns the geometric point of the intersection
-- between the line and the surface.

State(me)
---Purpose: Returns the state of the point on the face.
-- The values can be either TopAbs_IN
-- ( the point is in the face)
-- or TopAbs_ON
-- ( the point is on a boudary of the face).
