class Iterator from BRepSweep

	---Purpose: This class provides iteration services required by
	--          the Generating Line (TopoDS Shape) of a BRepSweep.
	--          This   tool is  used  to   iterate  on the  direct
	--          sub-shapes of a Shape.
	--          

uses

    Iterator from TopoDS,
    Shape from TopoDS,
    Orientation from TopAbs

raises

    NoMoreObject from Standard,
    NoSuchObject from Standard

is

    Create;

    Init(me : in out; aShape: Shape from TopoDS)
	---Purpose: Resest the Iterator on sub-shapes of <aShape>.
    is static;
    
    More(me) returns Boolean
	---Purpose: Returns True if there is a current sub-shape.

    Next(me : in out)
	---Purpose: Moves to the next sub-shape.
    raises
    	NoMoreObject from Standard
    is static;
    
    Value(me) returns Shape from TopoDS
	---Purpose: Returns the current sub-shape.
