class SplitShape from LocOpe
---Purpose: Provides a tool to cut :
-- - edges with a vertices,
-- - faces with wires,
-- and rebuilds the shape containing the edges and
-- the faces.
uses Vertex from TopoDS,
Edge from TopoDS,
Wire from TopoDS,
Face from TopoDS,
Shape from TopoDS,
ListOfShape from TopTools,

raises NotDone from StdFail,
ConstructionError from Standard,

---Purpose: Empty constructor.
returns SplitShape from LocOpe;
---C++: inline
Create(S: Shape from TopoDS)
---Purpose: Creates the process with the shape <S>.
returns SplitShape from LocOpe;
---C++: inline
Init(me: in out; S: Shape from TopoDS)
---Purpose: Initializes the process on the shape <S>.
is static;

---Purpose: Tests if it is possible to split the edge <E>.
returns Boolean from Standard

Add(me: in out; V: Vertex from TopoDS;
P: Real from Standard;
E: Edge from TopoDS)
---Purpose: Adds the vertex <V> on the edge <E>, at parameter <P>.
raises ConstructionError from Standard
-- The exception ConstructionError is raised if CanSplit
-- returns Standard_False, or if P is not inside the
-- parametric bounds <E>.
is static;
Add(me: in out; W: Wire from TopoDS;
F: Face from TopoDS)
---Purpose: Adds the wire <W> on the face <F>.
raises NoSuchObject from Standard,
-- if <F> does not belong to the original shape.
ConstructionError from Standard
-- for a closed wire, if it is not included in a
-- sub-face of <F>
-- for an open wire, if it does not begin and end on
-- wire(s) of a sub-face of <F>

---Purpose: Returns the "original" shape.
returns Shape from TopoDS

---Purpose: Returns the list of descendant shapes of <S>.

LeftOf(me: in out; W: Wire from TopoDS; F: Face from TopoDS)
---Purpose: Returns the "left" part defined by the wire <W> on
-- the face <F>. The returned list of shape is in
-- fact a list of faces. The face <F> is considered
-- with its topological orientation in the original
-- shape. <W> is considered with its orientation.
returns ListOfShape from TopTools
---C++: return const&
raises NoSuchObject from Standard
-- The exception is raised if the shape is null or does not
-- contain the face.
