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

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.

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.
