	Law_Interpol ()
	Constructs an empty interpolative evolution law. The function Set is used to define the law.

void	Set (const NCollection_Array1< gp_Pnt2d > &ParAndRad, const bool Periodic=false)
	Defines this evolution law by interpolating the set of 2D points ParAndRad. The Y coordinate of a point of ParAndRad is the value of the function at the parameter point given by its X coordinate. If Periodic is true, this function is assumed to be periodic. Warning.

void	SetInRelative (const NCollection_Array1< gp_Pnt2d > &ParAndRad, const double Ud, const double Uf, const bool Periodic=false)

void	Set (const NCollection_Array1< gp_Pnt2d > &ParAndRad, const double Dd, const double Df, const bool Periodic=false)
	Defines this evolution law by interpolating the set of 2D points ParAndRad. The Y coordinate of a point of ParAndRad is the value of the function at the parameter point given by its X coordinate. If Periodic is true, this function is assumed to be periodic. In the second syntax, Dd and Df define the values of the first derivative of the function at its first and last points. Warning.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

int	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

virtual void	Delete () const
	Memory deallocator for transient classes.

Constructs an empty interpolative evolution law. The function Set is used to define the law.

Member Function Documentation

◆ Set() [1/2]

void Law_Interpol::Set	(	const NCollection_Array1< gp_Pnt2d > &	ParAndRad,
		const bool	Periodic = false )

Defines this evolution law by interpolating the set of 2D points ParAndRad. The Y coordinate of a point of ParAndRad is the value of the function at the parameter point given by its X coordinate. If Periodic is true, this function is assumed to be periodic. Warning.

The X coordinates of points in the table ParAndRad must be given in ascendant order.
If Periodic is true, the first and last Y coordinates of points in the table ParAndRad are assumed to be equal. In addition, with the second syntax, Dd and Df are also assumed to be equal. If this is not the case, Set uses the first value(s) as last value(s).

◆ Set() [2/2]

void Law_Interpol::Set	(	const NCollection_Array1< gp_Pnt2d > &	ParAndRad,
		const double	Dd,
		const double	Df,
		const bool	Periodic = false )

Defines this evolution law by interpolating the set of 2D points ParAndRad. The Y coordinate of a point of ParAndRad is the value of the function at the parameter point given by its X coordinate. If Periodic is true, this function is assumed to be periodic. In the second syntax, Dd and Df define the values of the first derivative of the function at its first and last points. Warning.

The X coordinates of points in the table ParAndRad must be given in ascendant order.
If Periodic is true, the first and last Y coordinates of points in the table ParAndRad are assumed to be equal. In addition, with the second syntax, Dd and Df are also assumed to be equal. If this is not the case, Set uses the first value(s) as last value(s).

◆ SetInRelative() [1/2]

void Law_Interpol::SetInRelative	(	const NCollection_Array1< gp_Pnt2d > &	ParAndRad,
		const double	Ud,
		const double	Uf,
		const bool	Periodic = false )

◆ SetInRelative() [2/2]
