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.

A sort of virtual copy constructor, this function returns a copy of the finite element object. Derived classes need to override the function here in this base class and return an object of the same type as the derived class.
Some places in the library, for example the constructors of FESystem as well as the hp::FECollection class, need to make copies of finite elements without knowing their exact type. They do so through this function.

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.

Return whether this element dominates another one given as argument fe_other, whether it is the other way around, whether neither dominates, or if either could dominate. The codim parameter describes the codimension of the investigated subspace and specifies that it is subject to this comparison. For example, if codim==0 then this function compares which element dominates at the cell level. If codim==1, then the elements are compared at faces, i.e., the comparison happens between the function spaces of the two finite elements as restricted to a face. Larger values of codim work correspondingly.
For a definition of domination, see FiniteElementDomination::Domination and in particular the hp paper.

This function returns true, if the shape function shape_index has non-zero function values somewhere on the face face_index.

Determine an estimate for the memory consumption (in bytes) of this object.
This function is made virtual, since finite element objects are usually accessed through pointers to their base class, rather than the class itself.

Only for internal use. Its full name is get_dofs_per_object_vector function and it creates the dofs_per_object vector that is needed within the constructor to be passed to the constructor of FiniteElementData.
