Detailed Description
class Dune::PDELab::ElementMapper< GV >
Class providing a consecutive index for codim 0 entities of a GridView.
ElementMapper yields a unique, consecutive, zero-based index for all codim 0 entities of a GridView. Conceptually, this can also be achieved using a Mapper from dune-grid, but this implementation has better performance as it avoids looking up the GeometryType in a std::map. For the common case of grids with a single codim 0 GeometryType, ElementMapper is specialized to just look up the cell index on the IndexSet of the GridView.
- Template Parameters
-
GV The type of the GridView to operate on.
