class Substitution from BRepTools
---Purpose: A tool to substitute subshapes by other shapes.
--
--
-- The user use the method Substitute to define the
-- modifications.
-- A set of shapes is designated to replace a initial
-- shape.
--
-- The method Build reconstructs a new Shape with the
-- modifications.The Shape and the new shape are
-- registered.
--
uses
Shape from TopoDS,
ListOfShape from TopTools,
DataMapOfShapeListOfShape from TopTools
raises
NoSuchObject from Standard
is
Create returns Substitution from BRepTools;
Clear ( me : in out)
---Purpose: Reset all the fields.
is static;
Substitute (me : in out;
OldShape : Shape from TopoDS;
NewShapes : ListOfShape from TopTools)
---Purpose: <Oldshape> will be replaced by <NewShapes>.
--
-- <NewShapes> can be empty , in this case <OldShape>
-- will disparate from its ancestors.
--
-- if an item of <NewShapes> is oriented FORWARD.
-- it will be oriented as <OldShape> in its ancestors.
-- else it will be reversed.

Build (me : in out; S : Shape from TopoDS)
---Purpose: Build NewShape from <S> if its subshapes has modified.
--
-- The methods <IsCopied> and <Copy> allows you to keep
-- the resul of <Build>
is static;
IsCopied(me; S : Shape from TopoDS) returns Boolean
---Purpose: Returns True if <S> has been replaced .
is static;
Copy(me; S : Shape from TopoDS) returns ListOfShape from TopTools
---Purpose: Returns the set of shapes substitued to <S> .
---C++: return const &
