---Purpose:
uses
HDataStructure from TopOpeBRepDS,
Kind from TopOpeBRepDS,
Shape from TopoDS,
Wire from TopoDS,
Face from TopoDS,
Vertex from TopoDS,
ListOfInteger from TColStd,

Create returns DSAccess from BRepAlgo;
Init(me: in out);
---Purpose: Clears the internal data structure, including the
--Shapes of Load().
-- Filling of the DS
Load(me : in out; S : Shape from TopoDS);
---Purpose: Loads the shape in DS.
--
Load(me : in out; S1, S2 : in out Shape from TopoDS);
---Purpose: Loads two shapes in the DS without intersecting them.
Intersect(me : in out);
---Purpose: Intersects two shapes at input and loads the DS with
-- their intersection. Clears the TopOpeBRepBuild_HBuilder if
-- necessary
Intersect(me : in out; S1, S2 : Shape from TopoDS);
---Purpose: Intersects the faces contained in two given shapes
-- and loads them in the DS. Clears the TopOpeBRepBuild_HBuilder
-- if necessary
SameDomain(me : in out;S1, S2 : Shape from TopoDS);
---Purpose: This method does the same thing as the previous,
-- but faster. There is no intersection face/face 3D.
-- The faces have the same support(surface). No test of
-- tangency (that is why it is faster). Intersects in 2d
-- the faces tangent F1 anf F2.
-- Construction des Sections
GetSectionEdgeSet(me : in out; S1,S2 : Shape from TopoDS)
---Purpose: returns compounds of Edge connected with section, which
-- contains sections between faces contained in S1 and S2.
-- returns an empty list of Shape if S1 or S2 do not contain
-- face.
-- calls GetSectionEdgeSet() if it has not already been done
---C++: return const &
returns ListOfShape from TopTools;
GetSectionEdgeSet(me : in out)
---Purpose: returns all compounds of edges connected with section
-- contained in the DS
---C++: return const &
returns ListOfShape from TopTools;
IsWire(me : in out;Compound : Shape from TopoDS)
---Purpose: NYI
returns Boolean from Standard;
Wire(me : in out;Compound : Shape from TopoDS)
---Purpose: NYI
---C++: return const &
returns Shape from TopoDS;
SectionVertex(me : in out;S1 : Shape from TopoDS;S2 : Shape from TopoDS)
---Purpose: NYI
-- returns the vertex of section, which contains the section
-- between face S1 and edge S2 (returns an empty Shape
-- if S1 is not a face or if S2 is not an edge)
---C++: return const &
returns ListOfShape from TopTools;
-- Edition de la SD
SuppressEdgeSet(me : in out; Compound : Shape from TopoDS);
---Purpose: Invalidates a complete line of section. All
-- Edges connected by Vertex or a Wire. Can be
-- a group of connected Edges, which do not form a
-- standard Wire.
ChangeEdgeSet(me : in out; Old, New : Shape from TopoDS);
---Purpose: Modifies a line of section. <New> -- should be a
-- Group of Edges connected by Vertex. -- Can be a
-- Wire. Can be a group of connected Edges that do not
-- form a standard Wire. <New> should be sub-groupn of <Old>
--
--
SuppressSectionVertex(me : in out;V : Vertex from TopoDS);
---Purpose: NYI
-- Make invalid a Vertex of section. The Vertex shoud be
-- reconstructed from a point.

-- Reconstruction des Shapes

---C++: return const &
returns Shape from TopoDS;
Propagate(me :in out;what : State from TopAbs;
FromShape : Shape from TopoDS;
LoadShape : Shape from TopoDS)
---Purpose: NYI Propagation of a state starting from the shape
-- FromShape = edge or vertex of section, face or
-- Coumpound de section. LoadShape is either S1,
-- or S2 (see the method Load). Propagation from
-- FromShape, on the states <what> of LoadShape.
-- Return a Wire in 2d, a Shell in 3d.
-- Specifications are incomplete, to be redefined for the typologies
-- correpsonding to <FromShape> and the result :
-- exemple : FromShape resultat
-- vertex wire (or edge)
-- edge of section face (or shell)
-- compound of section shell
-- ... ...
---C++: return const &
returns Shape from TopoDS;
PropagateFromSection(me : in out;SectionShape : Shape from TopoDS)
---Purpose: SectionShape est soit un Vertex de section(NYI), soit
-- une Edge de section. Propagation des shapes
-- de section en partant de SectionShape.
-- return un Compound de section.
---C++: return const &
returns Shape from TopoDS;
-- History
Modified (me: in out; S : Shape from TopoDS)
---Purpose: Returns the list of the descendant shapes of the shape <S>.
---C++: return const &
returns ListOfShape from TopTools ;
IsDeleted (me: in out; S : Shape from TopoDS)
---Purpose: Returns the fact that the shape <S> has been deleted or not
-- by the boolean operation.
returns Boolean;
-- Verification de la DS
Check(me : in out)
---Purpose: NYI
-- coherence of the internal Data Structure.
