static DEFINE_STANDARD_ALLOC void Value (const Handle< Geom2d_Curve > &C, const Standard_Real U, gp_Pnt2d &P)
 Computes the point.
static void D1 (const Handle< Geom2d_Curve > &C, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1)
 Computes the point.
static void D2 (const Handle< Geom2d_Curve > &C, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2)
 Computes the point.
static void D3 (const Handle< Geom2d_Curve > &C, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2, gp_Vec2d &V3)
 Computes the point.
static Standard_Integer Continuity (const Handle< Geom2d_Curve > &C)
 returns the order of continuity of the curve .
returns 1 : first derivative only is computable
returns 2 : first and second derivative only are computable.
returns 3 : first, second and third are computable.

static Standard_Real FirstParameter (const Handle< Geom2d_Curve > &C)
 returns the first parameter bound of the curve.


static Standard_Real LastParameter (const Handle< Geom2d_Curve > &C)
 returns the last parameter bound of the curve.
FirstParameter must be less than LastParameter.
