Detailed Description

template<int dim, int spacedim>
class DoFHandler< dim, spacedim >::MGVertexDoFs

A data structure that is used to store the DoF indices associated with a particular vertex. Unlike cells, vertices live on several levels of a multigrid hierarchy; consequently, we need to store DoF indices for each vertex for each of the levels it lives on. This class does this.

void DoFHandler< dim, spacedim >::MGVertexDoFs::init	(	const unsigned int	coarsest_level,
		const unsigned int	finest_level,
