LocalUniversalMapper (const G &grid) | |
int | map (const EntityType &e) const |
Map entity to array index. | |
int | map (const typename G::Traits::template Codim< 0 >::Entity &e, int i, int cc) const |
Map subentity of codim 0 entity to array index. | |
int | map (const typename G::Traits::template Codim< 0 >::Entity &e, int i, unsigned int codim) const |
Map subentity i of codim cc of a codim 0 entity to array index. | |
int | size () const |
Return total number of entities in the entity set managed by the mapper. | |
bool | contains (const EntityType &e, int &result) const |
Returns true if the entity is contained in the index set. | |
bool | contains (const typename G::Traits::template Codim< 0 >::Entity &e, int i, int cc, int &result) const |
Returns true if the entity is contained in the index set. | |

Universal mapper based on local ids.
Template parameters are:
Dune::LocalUniversalMapper< G >::LocalUniversalMapper | ( | const G & | grid | ) | [inline] |
void Dune::UniversalMapper< G, G::Traits::LocalIdSet >::clear | ( | ) | [inline, inherited] |
bool Dune::UniversalMapper< G, G::Traits::LocalIdSet >::contains | ( | const EntityType & | e, |
int & | result | ||
) | const [inline, inherited] |
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.
e | Reference to entity |
result | integer reference where corresponding index is stored if true |
Reimplemented from Dune::Mapper< G, UniversalMapper< G, G::Traits::LocalIdSet > >.
bool Dune::UniversalMapper< G, G::Traits::LocalIdSet >::contains | ( | const typename G::Traits::template Codim< 0 >::Entity & | e, |
int | i, | ||
int | cc, | ||
int & | result | ||
) | const [inline, inherited] |
Returns true if the entity is contained in the index set.
[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 |
Reimplemented from Dune::Mapper< G, UniversalMapper< G, G::Traits::LocalIdSet > >.
int Dune::UniversalMapper< G, G::Traits::LocalIdSet >::map | ( | const EntityType & | e | ) | const [inline, inherited] |
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.
e | Reference to codim cc entity, where cc is the template parameter of the function. |
Reimplemented from Dune::Mapper< G, UniversalMapper< G, G::Traits::LocalIdSet > >.
int Dune::UniversalMapper< G, G::Traits::LocalIdSet >::map | ( | const typename G::Traits::template Codim< 0 >::Entity & | e, |
int | i, | ||
int | cc | ||
) | const [inline, inherited] |
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.
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 |
int Dune::Mapper< G, UniversalMapper< G, G::Traits::LocalIdSet > >::map | ( | const typename G::Traits::template Codim< 0 >::Entity & | e, |
int | i, | ||
unsigned int | codim | ||
) | const [inline, inherited] |
Map subentity i of codim cc of a codim 0 entity to array index.
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 |
int Dune::UniversalMapper< G, G::Traits::LocalIdSet >::size | ( | ) | const [inline, inherited] |
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).

void Dune::UniversalMapper< G, G::Traits::LocalIdSet >::update | ( | ) | [inline, inherited] |
Recalculates map after mesh adaptation.
