Discontinuous finite elements evaluated at the mapped quadrature points.
Warning: this class does not work properly, yet. Don't use it!
This finite element implements complete polynomial spaces, that is, \(d\)-dimensional polynomials of order \(k\).
The polynomials are not mapped. Therefore, they are constant, linear, quadratic, etc. on any grid cell.
Since the polynomials are evaluated at the quadrature points of the actual grid cell, no grid transfer and interpolation matrices are available.
The purpose of this class is experimental, therefore the implementation will remain incomplete.
Besides, this class is not implemented for the codimension one case (spacedim != dim).

This element does not have an InternalData class, unlike all other elements, because the InternalData classes are used to store things that can be computed once and reused multiple times (such as the values of shape functions at quadrature points on the reference cell). However, because the element is not mapped, this element has nothing that could be computed on the reference cell – everything needs to be computed on the real cell – and consequently there is nothing we'd like to store in such an object. We can thus simply use the members already provided by FiniteElement::InternalDataBase without adding anything in a derived class in this class.

Given a set of update flags, compute which other quantities also need to be computed in order to satisfy the request by the given flags. Then return the combination of the original set of flags and those just computed.
As an example, if update_flags contains update_gradients a finite element class will typically require the computation of the inverse of the Jacobian matrix in order to rotate the gradient of shape functions on the reference cell to the real cell. It would then return not just update_gradients, but also update_covariant_transformation, the flag that makes the mapping class produce the inverse of the Jacobian matrix.
An extensive discussion of the interaction between this function and FEValues can be found in the How Mapping, FiniteElement, and FEValues work together documentation module.

If, on a vertex, several finite elements are active, the hp code first assigns the degrees of freedom of each of these FEs different global indices. It then calls this function to find out which of them should get identical values, and consequently can receive the same global DoF index. This function therefore returns a list of identities between DoFs of the present finite element object with the DoFs of fe_other, which is a reference to a finite element object representing one of the other finite elements active on this particular vertex. The function computes which of the degrees of freedom of the two finite element objects are equivalent, both numbered between zero and the corresponding value of dofs_per_vertex of the two finite elements. The first index of each pair denotes one of the vertex dofs of the present element, whereas the second is the corresponding index of the other finite element.
This being a discontinuous element, the set of such constraints is of course empty.
