static Standard_Real FirstParameter (const Standard_Address C)
static Standard_Real LastParameter (const Standard_Address C)
static GeomAbs_Shape Continuity (const Standard_Address C)
static Standard_Integer NbIntervals (const Standard_Address C)
 Returns the number of intervals for continuity
<S>. May be one if Continuity(myclass) >= <S>

static void Intervals (const Standard_Address C, TColStd_Array1OfReal &T)
 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()

static void GetInterval (const Standard_Address C, const Standard_Integer Index, const TColStd_Array1OfReal &Tab, Standard_Real &U1, Standard_Real &U2)
 output the bounds of interval of index <Index>
used if Type == Composite.

static Standard_Boolean IsClosed (const Standard_Address C)
static Standard_Boolean IsPeriodic (const Standard_Address C)
static Standard_Real Period (const Standard_Address C)
static gp_Pnt2d Value (const Standard_Address C, const Standard_Real U)
 Computes the point of parameter U on the curve.

static void D0 (const Standard_Address C, const Standard_Real U, gp_Pnt2d &P)
 Computes the point of parameter U on the curve.

static void D1 (const Standard_Address C, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V)
 Computes the point of parameter U on the curve
with its first derivative.
//! Raised if the continuity of the current interval
is not C1.

static void D2 (const Standard_Address C, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2)
 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.

static void D3 (const Standard_Address C, const Standard_Real U, gp_Pnt2d &P, gp_Vec2d &V1, gp_Vec2d &V2, gp_Vec2d &V3)
 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.

static gp_Vec2d DN (const Standard_Address C, const Standard_Real U, const Standard_Integer N)
 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.

static Standard_Real Resolution (const Standard_Address C, const Standard_Real R3d)
 Returns the parametric resolution corresponding
to the real space resolution <R3d>.

static GeomAbs_CurveType GetType (const Standard_Address C)
 Returns the type of the curve in the current
interval : Line, Circle, Ellipse, Hyperbola,
Parabola, BezierCurve, BSplineCurve, OtherCurve.

static GeomAbs_CurveType TheType (const Standard_Address C)
 Returns the type of the curve in the current
interval : Line, Circle, Ellipse, Hyperbola,
Parabola, BezierCurve, BSplineCurve, OtherCurve.
