template<typename G, typename IDS>
class Dune::UniversalMapper< G, IDS >
Implements a mapper for an arbitrary subset of entities.
This implementation uses an ID set and a map, thus it has log complexity for each access. Template parameters are:
Entities need to be registered in order to use them. If an entity is queried with map, the known index is returned or a new index is created. The method contains only return true, if the entites was queried via map already.
\par G
A Dune grid type.
\par IDS
An Id set for the given grid
template<typename G, typename IDS>
template<class EntityType >
Returns true if the entity is contained in the index set.
The method contains only return true, if the entites was queried via map already.
- Parameters:
-
e | Reference to entity |
result | integer reference where corresponding index is stored if true |
- Returns:
- true if entity is in entity set of the mapper

template<typename G, typename IDS>
template<class EntityType >
Map entity to array index.
If an entity is queried with map, the known index is returned or a new index is created. A call to map can never fail.
\param e Reference to codim cc entity, where cc is the template parameter of the function.
\return An index in the range 0 ... Max number of entities in set - 1.
Reimplemented from Dune::Mapper< G, UniversalMapper< G, IDS > >.
template<typename G, typename IDS>
Return total number of entities in the entity set managed by the mapper.
This number can be used to allocate a vector of data elements associated with the
entities of the set. In the parallel case this number is per process (i.e. it may be different in different processes).
\return Size of the entity set.
