Return an estimate (in bytes) for the memory consumption of this object.
Array with shape function values in quadrature points. There is one row for each shape function, containing values for each quadrature point.
In this array, we store the values of the shape function in the quadrature points on the unit cell. Since these values do not change under transformation to the real cell, we only need to copy them over when visiting a concrete cell.
Array with shape function gradients in quadrature points. There is one row for each shape function, containing values for each quadrature point.
We store the gradients in the quadrature points on the unit cell. We then only have to apply the transformation (which is a matrix-vector multiplication) when visiting an actual cell.
Array with shape function hessians in quadrature points. There is one row for each shape function, containing values for each quadrature point.
We store the hessians in the quadrature points on the unit cell. We then only have to apply the transformation when visiting an actual cell.
Array with shape function third derivatives in quadrature points. There is one row for each shape function, containing values for each quadrature point.
We store the third derivatives in the quadrature points on the unit cell. We then only have to apply the transformation when visiting an actual cell.

A set of update flags specifying the kind of information that an implementation of the FiniteElement interface needs to compute on each cell or face, i.e., in FiniteElement::fill_fe_values() and friends.
This set of flags is stored here by implementations of FiniteElement::get_data(), FiniteElement::get_face_data(), or FiniteElement::get_subface_data(), and is that subset of the update flags passed to those functions that require re-computation on every cell. (The subset of the flags corresponding to information that can be computed once and for all already at the time of the call to FiniteElement::get_data() – or an implementation of that interface – need not be stored here because it has already been taken care of.)
