	--          GeomAbs_Ellipse.
        ---C++: inline
    	returns Elips2d from gp;


    Parabola(myclass; C: IntCurveCurve)
    
	---Purpose: Returns the Parab2d from gp corresponding to the curve C.
	--          This method is called only when TheType returns
	--          GeomAbs_Parabola.
        ---C++: inline
    	returns Parab2d from gp;


    Hyperbola(myclass; C: IntCurveCurve)
    
	---Purpose: Returns the Hypr2d from gp corresponding to the curve C.

	--          GeomAbs_Hyperbola.
        ---C++: inline
    	returns Hypr2d from gp;


-- The following method are used only when TheType returns  IntCurve_Other.
