Detailed Description

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

◆ StaticFixedStorage() [1/3]

template<typename T , int Num>
Sacado::Fad::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

References Sacado::Fad::StaticFixedStorage< T, Num >::dx_, and Sacado::ss_array< T, isScalar >::zero().

◆ StaticFixedStorage() [2/3]

template<typename T , int Num>
Sacado::Fad::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.

References Sacado::Fad::StaticFixedStorage< T, Num >::dx_.

◆ StaticFixedStorage() [3/3]

template<typename T , int Num>
Sacado::Fad::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 SACADO_INLINE_FUNCTION.

Member Function Documentation

◆ operator=()

template<typename T , int Num>
StaticFixedStorage & Sacado::Fad::StaticFixedStorage< T, Num >::operator= ( const StaticFixedStorage< T, Num > &  x)
inline

Assignment.

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