uses

raises
     NoMoreObject from Standard,
     NoSuchObject from Standard 

is

	---Purpose: Iterates from the current Shape in <anIterator>

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

    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&
       	---Purpose:  Warning! Can be a Null Shape if a descendant is deleted.
    raises
	NoSuchObject from Standard;
	
    IsModification(me) returns Boolean;
	---Purpose: True if the new  shape is a modification  (split,
	--          fuse,etc...) of the old shape.
