Detailed Description

template<class HGV>
class Dune::Functions::Experimental::SubDomainIndexSet< HGV >

An IndexSet for a sub-domain.

A SubDomainIndexSet provides indices for a subset of the entities of a grid view. Once created, new entities can be inserted using subDomainIndexSet.insertElement(element) which will insert the grid element of codim 0 and all its sub entities. This will increment the internally stored size information accordingly. Querying the index of an entity or sub-entity that has not been inserted before will lead to an exception.

Internally this uses a std::vector<std::size_t> which stores the sub-domain index for each entity in the underlying grid view using a magic value for entities not contained in the sub-domain.

Template Parameters

HGV	The underlying host grid view type.
