.
const Handle_Geom_Curve & Curve () const
 Provides a curve inherited from Hcurve from Adaptor.
This is inherited to provide easy to use constructors.
.

Standard_EXPORT GeomAbs_Shape Continuity () const
Standard_EXPORT Standard_Integer NbIntervals (const GeomAbs_Shape S)
 Returns the number of intervals for continuity
<s>. May be one if Continuity(me) >= <s>
.
Standard_EXPORT 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()
.
Standard_EXPORT 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.

 Returns the point P of parameter U, the first, the second
and the third derivative.

Warning : On the specific case of BSplineCurve:
if the curve is cut in interval of continuity at least C3, the
derivatives are computed on the current interval.
else the derivatives are computed on the basis curve.
.
Standard_EXPORT gp_Vec 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.
Warning : On the specific case of BSplineCurve:
if the curve is cut in interval of continuity CN, the
derivatives are computed on the current interval.
else the derivatives are computed on the basis curve.
//! Raised if N < 1.
