class FaceBuilder from TopOpeBRepBuild
uses
Shape from TopoDS,
Face from TopoDS,
ListOfShape from TopTools,
IndexedMapOfShape from TopTools,
IndexedDataMapOfShapeShape from TopTools,
ShapeSet from TopOpeBRepBuild,

is
Create returns FaceBuilder;
Create(ES : in out WireEdgeSet; F : Shape from TopoDS;
ForceClass : Boolean = Standard_False) returns FaceBuilder;
---Purpose: Create a FaceBuilder to build the faces on
-- the shapes (wires, blocks of edge) described by <LS>.
InitFaceBuilder(me : in out;
ES : in out WireEdgeSet; F : Shape from TopoDS;
ForceClass : Boolean);
DetectUnclosedWire(me : in out;
mapVVsameG : out IndexedDataMapOfShapeShape from TopTools;
mapVon1Edge : out IndexedDataMapOfShapeShape from TopTools);
---Purpose: Removes are non 3d-closed wires.
-- Fills up maps <mapVVsameG> and <mapVon1Edge>, in order to
-- correct 3d-closed but unclosed (topologic connexity) wires.
-- modifies myBlockBuilder
CorrectGclosedWire(me : in out;
mapVVref : IndexedDataMapOfShapeShape from TopTools;
mapVon1Edge : IndexedDataMapOfShapeShape from TopTools);
---Purpose: Using the given maps, change the topology of the 3d-closed
-- wires, in order to get closed wires.
DetectPseudoInternalEdge(me : in out;
mapE : out IndexedMapOfShape from TopTools);
---Purpose: Removes edges appearing twice (FORWARD,REVERSED) with a bounding
-- vertex not connected to any other edge.
-- mapE contains edges found.
-- modifies myBlockBuilder.
Face(me) returns Shape from TopoDS;
---C++: return const &
---Purpose: return myFace
-- Output methods
InitFace(me : in out) returns Integer from Standard;
MoreFace(me) returns Boolean from Standard;
NextFace(me : in out);
-- Exploration of the wires of the current face
InitWire(me : in out) returns Integer from Standard;
MoreWire(me) returns Boolean from Standard;
NextWire(me : in out);
IsOldWire(me) returns Boolean from Standard;
OldWire(me) returns Shape from TopoDS;
---Purpose: Returns current wire
-- This wire may be :
-- * an old wire OldWire(), which has not been reconstructed;
-- * a new wire made of edges described by ...NewEdge() methods.
---C++: return const &
-- Exploration of the edges of current wire when IsOldWire = False
FindNextValidElement(me : in out);
---Purpose: Iterates on myBlockIterator until finding a valid element
InitEdge(me : in out) returns Integer from Standard;
MoreEdge(me) returns Boolean from Standard;
NextEdge(me : in out);
Edge(me) returns Shape from TopoDS;
---Purpose: Returns current new edge of current new wire.
---C++: return const &
EdgeConnexity(me;E:Shape) returns Integer;
AddEdgeWire(me;E:Shape;W:in out Shape)
returns Integer;
