Detailed Description

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

Derivative array storage class using static memory allocation.

This class uses a statically allocated array whose dimension is fixed by the template parameter Num.

Constructor & Destructor Documentation

template<typename T , int Num>
KOKKOS_INLINE_FUNCTION Sacado::Fad::Exp::StaticStorage< T, Num >::StaticStorage ( const int  sz,
const T &  x,
const DerivInit  zero_out 
)
inline

Member Function Documentation

template<typename T , int Num>
KOKKOS_INLINE_FUNCTION void Sacado::Fad::Exp::StaticStorage< T, Num >::expand ( int  sz)
inline

Expand derivative array to size sz.

This method preserves any existing derivative components and sets any that are added to zero.

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

template<typename T , int Num>
KOKKOS_INLINE_FUNCTION void Sacado::Fad::Exp::StaticStorage< T, Num >::resizeAndZero ( int  sz)
inline

Resize the derivative array to sz.

This method doest not preserve any existing derivative components but sets any that are added to zero.

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