class NumShapeIterator from Sweep

	---Purpose: This class provides iteration services required by
	--          the   Swept Primitives  for   a Directing NumShape
	--          Line.
	--          

uses

    NumShape from Sweep,
    Orientation from TopAbs

raises

    NoMoreObject from Standard,
    NoSuchObject from Standard

is

    Create returns NumShapeIterator from Sweep;

    Init(me : in out; aShape: NumShape from Sweep)
	---Purpose: Resest the NumShapeIterator 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.
