class Builder from LocOpe
---Purpose: Provides a basic tool to implement local
-- topological operations.

---Purpose: Empty constructor.
returns Builder from LocOpe;
Create(S: Shape from TopoDS)
---Purpose: Creates a builder for local operations on <S>.
returns Builder from LocOpe
raises ConstructionError from Standard;
--- The exception is raised if <S> is a null shape.
Create(S: Shape from TopoDS; Tool: Shape from TopoDS)
---Purpose: Creates a builder for local operations between <S>
-- and <Tool>.
returns Builder from LocOpe

--- The exception is raised if <S> or <Tool> is a null shape .

---Purpose: Initializes a builder for local operations on <S>.

--- The exception is raised if <S> is a null shape.

---Purpose: Initializes a builder for local operations between

--- The exception is raised if <S> or <Tool>is a null shape.
is static;
Perform(me: in out; Tool : Shape from TopoDS;
L : ListOfShape from TopTools;
Fuse : Boolean from Standard)
---Purpose: Performs the local operation on the formerly given
-- shape. <L> defines a set of faces of the
-- shape. The whole tool is used. The list may not be
-- empty. The boolean <Fuse> gives the type of
-- operation. If set to Standard_True, the operation
-- is a fusion. If set to Standard_False, the
-- operation is a cutting one.
--
-- The Perform process stops just before constructing
-- any result in order to authorize the selection of
-- parts of the tool. After a call to Perform, it is
-- possible to call BuilPartsOfTool, then
-- RemovePart/ActivatePart to select valid parts, and
-- it is necessary to call PerformResult to get any
-- result.
raises ConstructionError from Standard
-- The exception is raised if <Tool> is null or same as the shape.

Perform(me: in out; LShape : ListOfShape from TopTools;

Fuse : Boolean from Standard)
---Purpose: Performs the local operation on the formerly given
-- shape and tool. <LShape> defines a set of faces
-- of the shape. <LTool> defines a set of faces of
-- the tool. The boolean <Fuse> gives the type of
-- operation. If set to Standard_True, the operation
-- is a fusion. If set to Standard_False, the
-- operation is a cutting one. If <LShape> (resp.
-- <LTool>) is empty, the whole shape (resp. tool) is
-- used.

-- The Perform process stops just before constructing
-- any result in order to authorize the selection of
-- parts of the tool. After a call to Perform, it is
-- possible to call BuilPartsOfTool, then
-- RemovePart/ActivatePart to select valid parts, and

---Purpose: Builds every valid parts of the tool.
raises NotDone from StdFail
-- The exception is raised if no call to Perform has been done.

---Purpose: Returns the list of the parts of tool. Each of
-- this part is a TopoDS_Shell.

-- The exception is raised if no call to BuildPartsOfTool has
-- been done.

RemovePart(me: in out; S: Shape from TopoDS)
---Purpose: Removes <S> from the list of valid parts of tool.
raises NotDone from StdFail
-- The exception is raised if no call to BuildPartsOfTool has
-- been done.
is static;
ActivatePart(me: in out; S: Shape from TopoDS)
---Purpose: Removes <S> from the list of invalid parts of
-- tool. By default, all parts of tool are valid for
-- the local operation.
raises NotDone from StdFail
-- The exception is raised if no call to BuildPartsOfTool has
-- been done.
is static;
PerformResult(me: in out)
---Purpose: Invalidates the given parts of tools if any, and
-- performs the result of the local operation.
raises NotDone from StdFail
-- The exception is raised if no call to Perform has been done.
is static;
IsDone(me)
---Purpose: Returns Standard_True if the operation has been
-- successfuly done.
returns Boolean from Standard
---C++: inline

IsInvDone(me)
---Purpose: Returns Standard_True if the Invalidate Parts
-- operation has been successfuly done.
returns Boolean from Standard

ResultingShape(me)
---Purpose: Returns the result of the operation.
returns Shape from TopoDS
---C++: return const&
---C++: inline
raises NotDone from StdFail
-- The exception is raised if IsDone returns Standard_False.
is static;

---Purpose: Returns the shape on which the operation is defined.
