Constructor & Destructor Documentation

Law_Linear::Law_Linear ( )

Constructs an empty linear evolution law.

Member Function Documentation

void Law_Linear::Bounds ( Standard_Real PFirst,
Standard_Real PLast 
)
virtual

Returns the parametric bounds of the function.

Implements Law_Function.

GeomAbs_Shape Law_Linear::Continuity ( ) const
virtual

Returns GeomAbs_CN.

Implements Law_Function.

void Law_Linear::D1 ( const Standard_Real  X,
Standard_Real F,
Standard_Real D 
)
virtual

Returns the value F and the first derivative D of this function at the point of parameter X.

Implements Law_Function.

void Law_Linear::D2 ( const Standard_Real  X,
Standard_Real F,
Standard_Real D,
Standard_Real D2 
)
virtual

Returns the value, first and second derivatives at parameter X.

Implements Law_Function.

void Law_Linear::Intervals ( TColStd_Array1OfReal T,
const GeomAbs_Shape  S 
) const
virtual

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()

Implements Law_Function.

Standard_Integer Law_Linear::NbIntervals ( const GeomAbs_Shape  S) const
virtual

Returns 1.

Implements Law_Function.

void Law_Linear::Set ( const Standard_Real  Pdeb,
const Standard_Real  Valdeb,
const Standard_Real  Pfin,
const Standard_Real  Valfin 
)

Defines this linear evolution law by assigning both:

  • the bounds Pdeb and Pfin of the parameter, and
  • the values Valdeb and Valfin of the function at these two parametric bounds.
Handle< Law_Function > Law_Linear::Trim ( const Standard_Real  PFirst,
const Standard_Real  PLast,
const Standard_Real  Tol 
) const
virtual

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.

Implements Law_Function.

Standard_Real Law_Linear::Value ( const Standard_Real  X)
virtual

Returns the value of this function at the point of parameter X.

Implements Law_Function.
