generic class Classifier2d from TopClass
(TheEdge as any;
TheIntersector as any) -- as Intersection2d from TopClass
---Purpose:
uses
Lin2d from gp,
CurveTransition from TopTrans,
Orientation from TopAbs,
State from TopAbs
raises
DomainError
is
Create returns Classifier2d from TopClass;
---Purpose: Creates an undefined classifier.
Reset(me : in out; L : Lin2d from gp; P : Real; Tol : Real)
---Purpose: Starts a classification process. The point to
-- classify is the origin of the line <L>. <P> is
-- the original length of the segment on <L> used to
-- compute intersections. <Tol> is the tolerance
-- attached to the line segment in intersections.
is static;
Compare(me : in out; E : TheEdge;
Or : Orientation from TopAbs)
---Purpose: Updates the classification process with the edge
-- <E> from the boundary.
raises
DomainError -- The classifier has not been set

Parameter(me) returns Real
---Purpose: Returns the current value of the parameter.

Intersector(me : in out) returns TheIntersector
---Purpose: Returns the intersecting algorithm.

---C++: return &
is static;
ClosestIntersection(me) returns Integer
---Purpose: Returns 0 if the last compared edge had no
-- relevant intersection. Else returns the index of
-- this intersection in the last intersection
-- algorithm.

State(me) returns State from TopAbs
---Purpose: Returns the current state of the point.

---Purpose: Returns the Standard_True if the closest intersection point
-- represents head or end of the edge. Returns Standard_False
-- otherwise.
