Sacado::Fad::ViewStorage< T, static_length, static_stride, U > Class Template Reference

Derivative array storage class that is a view into a contiguous memory allocation. It does not provide proper value semantics and thus should not be used in a general-purpose scalar type. More...

KOKKOS_INLINE_FUNCTION void Sacado::Fad::ViewStorage< T, static_length, static_stride, U >::resize ( int  sz)
inline

Resize the derivative array to sz.

Since we can't actually resize, we check for resizes to zero, which signify assigning a constant. Thus we zero out the derivative components.

template<typename T , unsigned static_length, unsigned static_stride, typename U >
KOKKOS_INLINE_FUNCTION void Sacado::Fad::ViewStorage< T, static_length, static_stride, U >::resizeAndZero ( int  )
inline

Resize the derivative array to sz.

We don't do anything here as this is used in the context of resizing the derivative array to zero and then back to some size > 0. Instead we zero out components when it is resized to zero above.
