generic class Classifier2d from TopClass

uses

Lin2d from gp,
|
|
CurveTransition from TopTrans,

Orientation from TopAbs,
|
|
State from TopAbs

|
raises
|

DomainError

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

Intersector(me : in out) returns TheIntersector
|

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.

-- represents head or end of the edge. Returns Standard_False
