Detailed Description

Describes an linear evolution law.

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.
