generic class Segment from IntStart
(TheVertex as any;
TheArc as any;
ThePathPoint as any) -- as PathPoint from IntStart (TheVertex,TheArc)
---Purpose: This class defines the intersection between two implicit
-- surfaces A and B, when this intersection is a part of an
-- arc of restriction .
-- It can be bounded or semi infinite;
-- the extremities of these curves are vertices(ThepathPoint).
raises DomainError from Standard
is
Create
---Purpose: Empty constructor.
returns Segment;
SetValue(me: in out; A: TheArc)
---Purpose: Defines the concerned arc.
---C++: inline
is static;
SetLimitPoint(me: in out; V: ThePathPoint; First: Boolean)
---Purpose: Defines the first point or the last point,
-- depending on the value of the boolean First.

Curve(me)
---Purpose: Returns the geometric curve on the surface 's domain
-- which is solution.
returns any TheArc

HasFirstPoint(me)
---Purpose: Returns True if there is a vertex (ThePathPoint) defining
-- the lowest valid parameter on the arc.
