static Standard_Boolean TopExp::CommonVertex	(	const TopoDS_Edge &	E1,
		const TopoDS_Edge &	E2,
		TopoDS_Vertex &	V
	)

static

 Finds   the  vertex <V> common   to  the two edges <br>
     <E1,E2>, returns True if this vertex exists. <br>

Warning: <V> has sense only if the value <True> is returned

static TopoDS_Vertex TopExp::FirstVertex	(	const TopoDS_Edge &	E,
		const Standard_Boolean	CumOri = `Standard_False`
	)

static

Returns the Vertex of orientation FORWARD in E. If
there is none returns a Null Shape.
CumOri = True : taking account the edge orientation

static TopoDS_Vertex TopExp::LastVertex	(	const TopoDS_Edge &	E,
		const Standard_Boolean	CumOri = `Standard_False`
	)

static

Returns the Vertex of orientation REVERSED in E. If
there is none returns a Null Shape.
CumOri = True : taking account the edge orientation

static void TopExp::MapShapes	(	const TopoDS_Shape &	S,
		const TopAbs_ShapeEnum	T,
		TopTools_IndexedMapOfShape &	M
	)

static

 Tool to explore a topological data structure. <br>//! Stores in the map <M> all  the sub-shapes of <S> <br>
     of type <T>. <br>

Warning: The map is not cleared at first.

static void TopExp::MapShapes	(	const TopoDS_Shape &	S,
		TopTools_IndexedMapOfShape &	M
	)

static

Stores in the map <M> all the sub-shapes of <S>.

		const TopAbs_ShapeEnum	TS,
		const TopAbs_ShapeEnum	TA,
		TopTools_IndexedDataMapOfShapeListOfShape &	M
	)

static

Stores in the map <M> all the subshape of <S> of <br>
    type <TS>  for each one append  to  the list all <br>
    the ancestors of type <TA>.  For example map all <br>
    the edges and bind the list of faces. <br>

Warning: The map is not cleared at first.

static void TopExp::Vertices	(	const TopoDS_Edge &	E,
		TopoDS_Vertex &	Vfirst,
		TopoDS_Vertex &	Vlast,
		const Standard_Boolean	CumOri = `Standard_False`
	)

static

Returns in Vfirst, Vlast the FORWARD and REVERSED
vertices of the edge <E>. May be null shapes.
CumOri = True : taking account the edge orientation

static void TopExp::Vertices	(	const TopoDS_Wire &	W,
		TopoDS_Vertex &	Vfirst,
		TopoDS_Vertex &	Vlast
	)

static

Returns in Vfirst, Vlast the first and last
vertices of the open wire <W>. May be null shapes.
if <W> is closed Vfirst and Vlast are a same
vertex on <W>.
if <W> is no manifold. VFirst and VLast are null
shapes.
