Detailed Description
class Dune::UniversalMapper< G, IDS, IndexType >
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.
- Template Parameters
-
G A Dune grid type. IDS An Id set type for the given grid. IndexType Number type used for the indices

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.

inlineinherited |
Map subentity i of codim cc of a codim 0 entity to array index.
- Parameters
-
e Reference to codim 0 entity. i Number of codim cc subentity of e, where cc is the template parameter of the function. codim codimension of subentity of e
- Returns
- An index in the range 0 ... Max number of entities in set - 1.
Map subentity i of codim cc of a codim 0 entity to array index.
- Parameters
-
e Reference to codim 0 entity. i Number of codim cc subentity of e, where cc is the template parameter of the function. codim codimension of subentity of e
- Returns
- An index in the range 0 ... Max number of entities in set - 1.
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).
- Returns
- Size of the entity set.
Returns true if the entity is contained in the index set and at the same time the array index is returned.
- Parameters
-
[in] e Reference to entity [out] result Filled with array index if entity is contained
- Returns
- true if entity is in entity set of the mapper
Returns true if the subentity is contained in the index set and at the same time the array index is returned.
- Parameters
-
[in] e Reference to codim 0 entity [in] i subentity number [in] cc subentity codim [out] result Filled with array index if entity is contained
- Returns
- true if entity is in entity set of the mapper
Reinitialize mapper after grid has been modified.

Map subentity of codim 0 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.
- Parameters
-
e Reference to codim 0 entity. i Number of codim cc subentity of e, where cc is the template parameter of the function. cc codim of the subentity
- Returns
- An index in the range 0 ... Max number of entities in set - 1.
Map subentity of codim 0 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.
- Parameters
-
e Reference to codim 0 entity. i Number of codim cc subentity of e, where cc is the template parameter of the function. cc codim of the subentity
- Returns
- An index in the range 0 ... Max number of entities in set - 1.
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).
- Returns
- Size of the entity set.
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
Returns true if the entity is contained in the index set
- Parameters
-
[in] e Reference to codim 0 entity [in] i subentity number [in] cc subentity codim [out] result integer reference where corresponding index is stored if true
- Returns
- true if entity is in entity set of the mapper
