virtual Standard_Real	FirstParameter () const
virtual Standard_Real	LastParameter () const
GeomAbs_Shape	Continuity () const
Standard_Integer	NbIntervals (const GeomAbs_Shape S)
	Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S>
void	Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S)
	Stores in <T> the parameters bounding the intervals of continuity <S>. The array must provide enough room to accomodate for the parameters. i.e. T.Length() > NbIntervals()
virtual Handle_Adaptor3d_HCurve	Trim (const Standard_Real First, const Standard_Real Last, const Standard_Real Tol) const
	Returns a curve equivalent of <me> between parameters <First> and <Last>. <Tol> is used to test for 3d points confusion.
virtual Standard_Real	Resolution (const Standard_Real R3d) const
	Returns the parametric resolution corresponding to the real space resolution <R3d>.

	Computes the point of parameter U on the curve.
virtual void	D1 (const Standard_Real AbsC, gp_Pnt &P, gp_Vec &V1) const
	Computes the point of parameter U on the curve with its first derivative. //! Raised if the continuity of the current interval is not C1.
virtual void	D2 (const Standard_Real AbsC, gp_Pnt &P, gp_Vec &V1, gp_Vec &V2) const
	Returns the point P of parameter U, the first and second derivatives V1 and V2. //! Raised if the continuity of the current interval is not C2.
virtual void	D3 (const Standard_Real AbsC, gp_Pnt &P, gp_Vec &V1, gp_Vec &V2, gp_Vec &V3) const
	Returns the point P of parameter U, the first, the second and the third derivative. //! Raised if the continuity of the current interval is not C3.
