const Handle_Geom2d_Curve & Curve () const
Standard_Real FirstParameter () const
Standard_Real LastParameter () const
GeomAbs_Shape Continuity () const
Standard_Integer NbIntervals (const GeomAbs_Shape S) const
 If necessary, breaks the curve in intervals of
continuity <S>. And returns the number of
intervals.

void Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const
 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()

Handle_Adaptor2d_HCurve2d 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.
//! If <First> >= <Last>

gp_Pnt2d Value (const Standard_Real U) const
 Computes the point of parameter U on the curve

void D0 (const Standard_Real U, gp_Pnt2d &P) const
 Computes the point of parameter U.

void D1 (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V) 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.

void D2 (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &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.

void D3 (const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2, gp_Vec2d &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.

gp_Vec2d DN (const Standard_Real U, const Standard_Integer N) const
 The returned vector gives the value of the derivative for the
order of derivation N.
//! Raised if the continuity of the current interval
is not CN.
//! Raised if N < 1.

Standard_Real Resolution (const Standard_Real Ruv) const
 returns the parametric resolution
