Public Member Functions

virtual Standard_EXPORT GeomAbs_Shape Continuity () const =0
virtual Standard_EXPORT Standard_Integer NbIntervals (const GeomAbs_Shape S) const =0
 Returns the number of intervals for continuity
<s>. May be one if Continuity(me) >= <s>
.
virtual Standard_EXPORT void Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const =0
 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 Standard_EXPORT Standard_Real Value (const Standard_Real X)=0
 Returns the value of the function at the point of parameter X.
.
virtual Standard_EXPORT void D1 (const Standard_Real X, Standard_Real &F, Standard_Real &D)=0
 Returns the value F and the first derivative D of the
function at the point of parameter X.
.
virtual Standard_EXPORT void D2 (const Standard_Real X, Standard_Real &F, Standard_Real &D, Standard_Real &D2)=0
 Returns the value, first and seconde derivatives
at parameter X.
.
virtual Standard_EXPORT Handle_Law_Function Trim (const Standard_Real PFirst, const Standard_Real PLast, const Standard_Real Tol) const =0
 Returns a law equivalent of <me> between
parameters <first> and <last>. <tol> is used to
test for 3d points confusion.
It is usfule to determines the derivatives
in these values <first> and <last> if
the Law is not Cn.
.
virtual Standard_EXPORT void Bounds (Standard_Real &PFirst, Standard_Real &PLast)=0
 Returns the parametric bounds of the function.
.
Standard_EXPORT const Handle (Standard_Type)&DynamicType() const
