Size calculation
The FiniteElementMap provides different methods to compute the size of the GridFunctionSpace (if possible) without iterating the grid. The approach is as follows (pseudo code): computeNumberOfDofs(GridView, FEM): if(FEM.fixedSize()): sum(FEM.size(gt)*GridView.size(gt) for gt in GeometryTypes) else sum(FEM.find(E).basis().size() for E in GridView.entities<0>())
static constexpr std::size_t	size (GeometryType gt)=delete
	if the FiniteElementMap is fixedSize, the size methods computes the number of DOFs for given GeometryType.

Detailed Description

template<class D, class R>
class Dune::PDELab::Pk1dLocalFiniteElementMap< D, R >

FiniteElementMap for the Pk basis in 1d.

Note

k is a runtime variable.

Template Parameters

D	Type to represent domain.
R	Type to represent range.

compute an upper bound for the local number of DOFs.

this upper bound is used to avoid reallocations in std::vectors used during the assembly.
