(TheVertex as any;
|
|
TheArc as any)
|
|
|
|
---Purpose:
|
|
|
|
uses Pnt from gp
|
|
|
|
is
|
|
|
|
-- Methods for an arc of restrictition
|
|
|
|
HasBeenSeen(myclass; A: TheArc)
|
|
|
|
---Purpose: Returns True if all the intersection point and edges
|
|
-- are known on the Arc.
|
|
|
|
returns Boolean from Standard;
|
|
|
|
-- The following methods are used when HasBeenSeen returns Standard_True
|
|
|
|
NbPoints(myclass; A: TheArc)
|
|
|
|
---Purpose: Returns the number of intersection points on the arc A.
|
|
|
|
returns Integer from Standard;
|
|
|
|
|
|
Value(myclass; A: TheArc; Index: Integer from Standard;
|
|
Pt: out Pnt from gp; Tol: out Real from Standard;
|
|
U: out Real from Standard);
|
|
|
|
---Purpose: Returns the value (Pt), the tolerance (Tol), and
|
|
-- the parameter (U) on the arc A , of the intersection
|
|
-- point of range Index.
|
|
|
|
|
|
IsVertex(myclass; A: TheArc; Index: Integer from Standard)
|
|
|
|
---Purpose: Returns True if the intersection point of range Index
|
|
-- corresponds with a vertex on the arc A.
|
|
|
|
returns Boolean from Standard;
|
|
|
|
|
|
Vertex(myclass; A: TheArc; Index: Integer from Standard;
|
|
Vtx: out TheVertex);
|
|
|
|
---Purpose: When IsVertex returns True, this method returns the
|
|
-- vertex on the arc A.
|
|
|
|
|
|
NbSegments(myclass; A: TheArc)
|
|
|
|
---Purpose: returns the number of part of A solution of the
|
|
-- of intersection problem.
|
|
|
|
returns Integer from Standard;
|
|
|
|
|
|
HasFirstPoint(myclass; A: TheArc; Index: Integer from Standard;
|
|
IndFirst: out Integer from Standard)
|
|
|
|
---Purpose: Returns True when the segment of range Index is not
|
|
-- open at the left side. In that case, IndFirst is the
|
|
-- range in the list intersection points (see NbPoints)
|
|
-- of the one which defines the left bound of the segment.
|
|
-- Otherwise, the method has to return False, and IndFirst
|
|
-- has no meaning.
|
|
|
|
returns Boolean from Standard;
|
|
|
|
|
|
HasLastPoint(myclass; A: TheArc; Index: Integer from Standard;
|
|
IndLast: out Integer from Standard)
|
|
|
|
---Purpose: Returns True when the segment of range Index is not
|
|
-- open at the right side. In that case, IndLast is the
|
|
-- range in the list intersection points (see NbPoints)
|
|
-- of the one which defines the right bound of the segment.
|
|
-- Otherwise, the method has to return False, and IndLast
|
|
-- has no meaning.
|
|
|
|
returns Boolean from Standard;

|
|
|
|
|
IsAllSolution(myclass; A: TheArc)
|
|
|
|
---Purpose: Returns True when the whole restriction is solution
|
|
-- of the intersection problem.
|
|
|
|
returns Boolean from Standard;
|
|
|
|
|
|
|
|
-- The following methods are used when HasBeenSeen returns Standard_False
|
|
|
|
NbSamplesOnArc(myclass; A: TheArc)
|
|
|
|
---Purpose: returns the number of points which is used to make
|
|
-- a sample on the arc. this number is a function of
|
|
-- the Surface and the CurveOnSurface complexity.
|
|
|
|
returns Integer from Standard;
|
|
|
|
|
|
Bounds(myclass; A: TheArc; Ufirst,Ulast: out Real from Standard);
|
|
|
|
---Purpose: Returns the parametric limits on the arc A.
|
|
-- These limits must be finite : they are either
|
|
-- the real limits of the arc, for a finite arc,
|
|
-- or a bounding box for an infinite arc.
|
|
|
|
|
|
Parameter(myclass; V: TheVertex; A: TheArc)
|
|
|
|
---Purpose: Returns the parameter of the vertex V on the arc A.

|
|
returns Real from Standard;
|
|
|
|
|
|
Tolerance(myclass; V: TheVertex; A: TheArc)
|
|
|
|
---Purpose: Returns the parametric tolerance on the arc used
|
|
-- to consider that the vertex and another point meet,
|
|
-- i-e if the difference between the parameter of the
|
|
-- Vertex and the parameter of the other point is less
|
|
-- than Tolerance, the point are "merged".
|
|
|
|
returns Real from Standard;
