Detailed Description

template<typename GFS, typename TreePath, typename Tag>
class Dune::PDELab::gfs::DefaultSubSpaceFeatures< GFS, TreePath, Tag >

Default features used by every subspace implementation.

Member Function Documentation

◆ size()

template<typename GFS , typename TreePath , typename Tag >
Traits::SizeType Dune::PDELab::gfs::DefaultSubSpaceFeatures< GFS, TreePath, Tag >::size ( ) const
inline

Returns the global size of the root space.

Warning
The semantics of this methods have changed with the introduction of Orderings: While this method used to return the size of the subspace only, it now behaves like globalSize() and returns the overall size of the root space! Calculating the size of the subspace might be a very expensive operation depending on the underlying orderings.
