class CurveTool from Geom2dGcc

	---Purpose: 

uses Curve from Geom2dAdaptor,
     Pnt2d from gp,
     Vec2d from gp

is

    FirstParameter(myclass; C: Curve from Geom2dAdaptor)
    	returns Real;

    LastParameter(myclass; C: Curve from Geom2dAdaptor)
    	returns Real;

    EpsX (myclass                           ; 
    	  C       : Curve from Geom2dAdaptor;
    	  Tol     : Real  from Standard     )
    	returns Real;

    NbSamples(myclass                    ;
    	      C       : Curve from Geom2dAdaptor)
    	returns Integer;

    Value (myclass; C: Curve from Geom2dAdaptor; X: Real)
    	returns Pnt2d from gp;

    D1 (myclass; C: Curve from Geom2dAdaptor; U: Real ; 
                 P: out Pnt2d; T: out Vec2d);

    D2 (myclass; C: Curve from Geom2dAdaptor; U: Real ; 
                 P: out Pnt2d; T,N: out Vec2d);

    D3 (myclass; C: Curve from Geom2dAdaptor; U: Real ; 
                 P: out Pnt2d; T,N,dN: out Vec2d);
