(BREP : ManifoldSolid, Shell, Face)
This includes definiting of Vertex and Edge Lists,
building of Edges and Loops

#include <IGESSolid_TopoBuilder.hxx>

Public Member Functions
DEFINE_STANDARD_ALLOC	IGESSolid_TopoBuilder ()
	Creates an empty TopoBuilder This creates also a unique VertexList and a unique EdgeList, empty, but which can be referenced from starting
void	Clear ()
	Resets the TopoBuilder for an entirely new operation (with a new EdgeList, a new VertexList, new Shells, ...)
void	AddVertex (const gp_XYZ &val)
	Adds a Vertex to the VertexList
Standard_Integer	NbVertices () const
	Returns the count of already recorded Vertices
const gp_XYZ &	Vertex (const Standard_Integer num) const
	Returns a Vertex, given its rank
Handle_IGESSolid_VertexList	VertexList () const
	Returns the VertexList. It can be referenced, but it remains empty until call to EndShell or EndSolid
void	AddEdge (const Handle< IGESData_IGESEntity > &curve, const Standard_Integer vstart, const Standard_Integer vend)
	Adds an Edge (3D) to the EdgeList, defined by a Curve and two number of Vertex, for start and end
Standard_Integer	NbEdges () const
	Returns the count of recorded Edges (3D)
void	Edge (const Standard_Integer num, Handle< IGESData_IGESEntity > &curve, Standard_Integer &vstart, Standard_Integer &vend) const
	Returns the definition of an Edge (3D) given its rank
Handle_IGESSolid_EdgeList	EdgeList () const
	Returns the EdgeList. It can be referenced, but it remains empty until call to EndShell or EndSolid
void	MakeLoop ()
	Begins the definition of a new Loop : it is the Current Loop All Edges (UV) defined by MakeEdge/EndEdge will be added in it The Loop can then be referenced but is empty. It will be filled with its Edges(UV) by EndLoop (from SetOuter/AddInner)
void	MakeEdge (const Standard_Integer edgetype, const Standard_Integer edge3d, const Standard_Integer orientation)
	Defines an Edge(UV), to be added in the current Loop by EndEdge <edgetype> gives the type of the edge <edge3d> identifies the Edge(3D) used as support The EdgeList is allways the current one <orientation gives the orientation flag It is then necessary to :
void	AddCurveUV (const Handle< IGESData_IGESEntity > &curve, const Standard_Integer iso)
	Adds a Parametric Curve (UV) to the current Edge(UV)
void	EndEdge ()
	Closes the definition of an Edge(UV) and adds it to the current Loop
void	MakeFace (const Handle< IGESData_IGESEntity > &surface)
	Begins the definition of a new Face, on a surface All Loops defined by MakeLoop will be added in it, according the closing call : SetOuter for the Outer Loop (by default, if SetOuter is not called, no OuterLoop is defined); AddInner for the list of Inner Loops (there can be none)
void	SetOuter ()
	Closes the current Loop and sets it Loop as Outer Loop. If no current Loop has yet been defined, does nothing.
void	AddInner ()
	Closes the current Loop and adds it to the list of Inner Loops for the current Face
void	EndFace (const Standard_Integer orientation)
	Closes the definition of the current Face, fills it and adds it to the current Shell with an orientation flag (0/1)
void	MakeShell ()
	Begins the definition of a new Shell (either Simple or in a Solid)
void	EndSimpleShell ()
	Closes the whole definition as that of a simple Shell
void	SetMainShell (const Standard_Integer orientation)
	Closes the definition of the current Shell as for the Main Shell of a Solid, with an orientation flag (0/1)
void	AddVoidShell (const Standard_Integer orientation)
	Closes the definition of the current Shell and adds it to the list of Void Shells of a Solid, with an orientation flag (0/1)
void	EndSolid ()
	Closes the whole definition as that of a ManifoldSolid Its call is exclusive from that of EndSimpleShell
Handle_IGESSolid_Shell	Shell () const
	Returns the current Shell. The current Shell is created empty by MakeShell and filled by EndShell
Handle_IGESSolid_ManifoldSolid	Solid () const
	Returns the current ManifoldSolid. It is created empty by Create and filled by EndSolid
Protected Member Functions
void	EndLists ()
	Closes the definition of Vertex and Edge Lists Warning : Called only by EndSimpleShell and EndSolid
void	EndLoop ()
	Closes the definition of a Loop and fills it Warning : EndLoop should not be called directly but through SetOuter or AddInner, which work on the current Face
void	EndShell ()
	Closes the definition of the current Shell Warning : EndShell should not be called directly but through EndSimpleShell (for a simple Shell), SetMainShell (for main Shell of a Solid) or AddVoidShell (to a Solid)
