uses

    returns OldShapeIterator from TNaming;
    
    
    Create(anIterator : OldShapeIterator from TNaming)
    returns OldShapeIterator from TNaming;
	---Purpose: Iterates from the current Shape in <anIterator>
	
    Create(anIterator  : Iterator from TNaming)
    returns OldShapeIterator from TNaming;
	---Purpose: Iterates from the current Shape in <anIterator>
	
    More(me) returns Boolean;
    	---C++: inline

    Next(me : in out)
    raises
       NoMoreObject from Standard;
				
    Label(me) returns Label from TDF
    raises
	NoSuchObject from Standard;
    
    NamedShape(me) returns NamedShape from TNaming
    raises
	NoSuchObject from Standard;
		
		
    Shape(me) returns Shape from TopoDS
	---C++: return const&
    raises
	NoSuchObject from Standard;
	
    IsModification(me) returns Boolean;
	---Purpose: True if the  new  shape is a modification  (split,
	--          fuse,etc...) of the old shape.
