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>())
bool	fixedSize () const
	a FiniteElementMap is fixedSize iif the size of the local functions space for each GeometryType is fixed. More...
std::size_t	size (GeometryType gt) const
	if the FiniteElementMap is fixedSize, the size methods computes the number of DOFs for given GeometryType. More...

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.

std::size_t Dune::PDELab::LocalFiniteElementMapInterface< LocalFiniteElementMapTraits< FE > , Imp >::size ( GeometryType  gt ) const

inlineinherited

if the FiniteElementMap is fixedSize, the size methods computes the number of DOFs for given GeometryType.
