    Add(me : in out; E : Edge from TopoDS) 
   	---Purpose: Adds a  contour in  the  builder  (builds a
    	--          contour  of tangent edges).
    	---Level: Public
    is deferred;

    ResetContour(me     : in out; 
                 IC     : Integer from Standard) 
   	---Purpose: Reset the contour of index IC, there is nomore 
   	--          information in the contour.
    	---Level: Public
    is deferred;

    NbContours(me) 
	---Purpose: Number of contours. 
	---Level: Advanced
    returns Integer from Standard is deferred;

    Contour(me; E : Edge from TopoDS) 
        ---Purpose: Returns the index of  the  contour containing the edge
        --          E, returns 0 if E doesn't belong to any contour.
	---Level: Public
    returns Integer from Standard is deferred;

    NbEdges(me; I : Integer from Standard) 
        ---Purpose: Number of Edges in the contour I. 
        --          
	---Level: Advanced
    returns Integer from Standard 	
    is deferred;
    
    Edge(me; I,J : Integer from Standard) 
        ---Purpose: Returns the Edge J in the contour I. 
        --          
        ---C++: return const &
	---Level: Advanced
    returns Edge from TopoDS 
    is deferred;

    Remove(me : in out; E : Edge from TopoDS) 
        ---Purpose: remove the contour containing the Edge E.
	---Level: Advanced
    is deferred;

    Length(me; IC : Integer from Standard) returns Real from Standard
    ---Purpose: returns the length the contour of index IC.
    is deferred; 

    FirstVertex(me; IC : Integer from Standard) returns Vertex from TopoDS
        ---Purpose: Returns the first Vertex of the contour of index IC.
	---Level: Advanced
    is deferred;

    LastVertex(me; IC : Integer from Standard) returns Vertex from TopoDS
        ---Purpose: Returns the last Vertex of the contour of index IC.
	---Level: Advanced

    Abscissa(me; 
    	     IC : Integer from Standard;
             V  : Vertex  from TopoDS) 
    returns Real from Standard
    ---Purpose: returns the abscissa of the vertex V on
    --          the contour of index IC.
    is deferred;

    RelativeAbscissa(me; 
    	    	     IC : Integer from Standard;
                     V  : Vertex  from TopoDS) 
    returns Real from Standard
    ---Purpose: returns the relative abscissa([0.,1.]) of the 
    --          vertex V on the contour of index IC.
    is deferred;

    ClosedAndTangent(me; IC : Integer from Standard) 
    returns Boolean from Standard
    ---Purpose: returns true if the contour of index IC is closed
    --          an tangent.
    is deferred; 

    Closed(me; IC : Integer from Standard) 
    returns Boolean from Standard
    ---Purpose: returns true if the contour of index IC is closed
    is deferred; 

    Reset(me : in out)
    ---Purpose: Reset all the fields updated   by Build operation  and
    --          leave the  algorithm in  the  same state  than  before
    --          build    call.  It   allows   contours    and   radius
    --          modifications  to build the result another time.
