Member Data Documentation

cell_info

template<class P, class D, class B, class E>

std::span<const std::uint32_t> cell_info

Cell permutations for this argument's mesh. Empty if the element needs no dof transformations.

transform

template<class P, class D, class B, class E>

const P& transform

Dof transformation applied in-place to the element tensor. Held by reference because it may be a std::function, whose copy allocates.
