Detailed Description

template<typename T, int Num>
class Sacado::Fad::Exp::StaticFixedStorage< T, Num >

Derivative array storage class using static, fixed memory allocation.

This class uses a statically allocated array whose dimension is fixed by the template parameter Num. The dimension cannot be resized.

Constructor & Destructor Documentation

template<typename T , int Num>

KOKKOS_DEFAULTED_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::StaticFixedStorage ( )

default

Default constructor.

template<typename T , int Num>

KOKKOS_INLINE_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::StaticFixedStorage ( const T & x )

inline

Constructor with value.

Definition at line 85 of file Sacado_Fad_Exp_StaticFixedStorage.hpp.

template<typename T , int Num>

KOKKOS_INLINE_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::StaticFixedStorage	(	const int	sz,
		const T &	x,
		const DerivInit	zero_out = `InitDerivArray`
	)

inline

Constructor with size sz.

Initializes derivative array 0 of length sz

Definition at line 95 of file Sacado_Fad_Exp_StaticFixedStorage.hpp.

template<typename T , int Num>

KOKKOS_INLINE_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::StaticFixedStorage	(	const int	sz,
		const int	i,
		const value_type &	x
	)

inline

Constructor with size sz, index i, and value x.

Initializes value to x and derivative array of length sz as row i of the identity matrix, i.e., sets derivative component i to 1 and all other's to zero.

Definition at line 113 of file Sacado_Fad_Exp_StaticFixedStorage.hpp.

template<typename T , int Num>

KOKKOS_INLINE_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::StaticFixedStorage ( const StaticFixedStorage< T, Num > & x )

inline

Copy constructor.

Can't make this " = default" because of scalar types that don't define a const copy consturctor (like Rad). We also can't leave it and let it be implicitly generated because of KOKKOS_INLINE_FUNCTION.

template<typename T , int Num>

KOKKOS_INLINE_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::StaticFixedStorage ( StaticFixedStorage< T, Num > && x )

inline

Move constructor.

template<typename T , int Num>

KOKKOS_DEFAULTED_FUNCTION Sacado::Fad::Exp::StaticFixedStorage< T, Num >::~StaticFixedStorage ( )

default

Destructor.
