deferred generic class CurveTool from IntImp (Curve as any)

	---Purpose: Template class for the methods on a curve.
	--          It is possible to implement this class with
	--          an instantiation of the CurveTool from Adaptor3d.

uses Pnt from gp,

is

    FirstParameter(myclass;C : Curve ) returns Real;
    
    LastParameter(myclass;C : Curve ) returns Real;

    Resolution(myclass; C : Curve; Tol3d: Real from Standard)
    
        ---Purpose :  Returns the parametric  resolution corresponding
        --         to the space resolution Tol3d.

    	returns Real from Standard;
