Dune::DefaultEmptyIndexSet Class Reference
#include <defaultindexsets.hh>
Inheritance diagram for Dune::DefaultEmptyIndexSet:

Detailed Description
The DefaultGridIndexSet is a wrapper for the grid index which can be index of entity or globalIndex. The DofMapper uses an IndexSet for mapping the dofs, so we can hide the real grid index behind the index set. Furthermore if a grid doesn't provide the consecutive index set then this can be calculated in the IndexSet. These two following index sets are just the identiy to the grid indices.The DefaultGridIndexSetBase defines some methods that are needed for index sets that cope with adaptation, but aren't needed for the following index set, so most of this methods do notin'.
