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...

a FiniteElementMap is fixedSize iif the size of the local functions space for each GeometryType is fixed.

std::size_t Dune::PDELab::LocalFiniteElementMapInterface< LocalFiniteElementMapTraits< Imp > , SimpleLocalFiniteElementMap< Imp > >::maxLocalSize ( ) const

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< Imp > , SimpleLocalFiniteElementMap< Imp > >::size ( GeometryType  gt ) const

inlineinherited

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