Detailed Description

template<class GridImp, class IteratorImp>
class Dune::DefaultIndexSet< GridImp, IteratorImp >

DefaultIndexSet creates an index set by using the grids persistent container an a given pair of iterators.

Constructor & Destructor Documentation

DefaultIndexSet()

template<class GridImp , class IteratorImp >

Dune::DefaultIndexSet< GridImp, IteratorImp >::DefaultIndexSet ( const GridType &  grid, const IteratorType &  begin, const IteratorType &  end, const int  level = -1  )

inline

create index set by using the given begin and end iterator for the given level (level == -1 means leaf level)

References Dune::DefaultIndexSet< GridImp, IteratorImp >::calcNewIndex().

Member Function Documentation

calcNewIndex()

template<class GridImp , class IteratorImp >

void Dune::DefaultIndexSet< GridImp, IteratorImp >::calcNewIndex ( const IteratorType &  begin, const IteratorType &  end  )

inline

do calculation of the index set, has to be called when grid was changed or if index set is created

index() [1/2]

IndexType Dune::IndexSet< GridImp, DefaultIndexSet< GridImp, IteratorImp > , unsigned int , TypesImp >::index ( const Entity &  e ) const

inlineinherited

Map entity to index. Easier to use than the above because codimension template parameter need not be supplied explicitly. The result of calling this method with an entity that is not in the index set is undefined.

Parameters

e	Reference to codim cc entity. Since entity knows its codimension, automatic extraction is possible.

Returns

An index in the range 0 ... Max number of entities in set - 1.

index() [2/2]

IndexType Dune::IndexSet< GridImp, DefaultIndexSet< GridImp, IteratorImp > , unsigned int , TypesImp >::index ( const typename Traits::template Codim< cc >::Entity &  e ) const

inlineinherited

Map entity to index. The result of calling this method with an entity that is not in the index set is undefined.

Parameters

e	Reference to codim cc entity, where cc is the template parameter of the function.

Returns

An index in the range 0 ... Max number of entities in set - 1.

size()

template<class GridImp , class IteratorImp >

IndexType Dune::DefaultIndexSet< GridImp, IteratorImp >::size ( GeometryType  type ) const

inline

return size of IndexSet for a given level and codim this method is to be revised

References Dune::GeometryType::dim().

subIndex() [1/3]

IndexType Dune::IndexSet< GridImp, DefaultIndexSet< GridImp, IteratorImp > , unsigned int , TypesImp >::subIndex ( const Entity &  e, int  i, unsigned int  codim  ) const

inlineinherited

Map a subentity to an index.

The result of calling this method with an entity that is not in the index set is undefined.

Note

This method exists for convenience only. It extracts the codimension from the type of the entity, which can be guessed by the compiler.

Template Parameters

Entity

type of entity (must be GridImp::Codim< cc >::Entity for some cc)

Parameters

[in]	e	reference to entity
[in]	i	number subentity of e within the codimension
[in]	codim	codimension of the subentity we're interested in

Returns

An index in the range 0 ... Max number of entities in set - 1.

subIndex() [2/3]

template<class GridImp , class IteratorImp >

template<int cc>

IndexType Dune::DefaultIndexSet< GridImp, IteratorImp >::subIndex ( const typename remove_const< GridImp >::type::Traits::template Codim< cc >::Entity &  e, int  i, unsigned int  codim  ) const

inline

return subIndex (LevelIndex) for a given Entity of codim = 0 and a given SubEntity codim and number of SubEntity

subIndex() [3/3]

IndexType Dune::IndexSet< GridImp, DefaultIndexSet< GridImp, IteratorImp > , unsigned int , TypesImp >::subIndex ( const typename Traits::template Codim< cc >::Entity &  e, int  i, unsigned int  codim  ) const

inlineinherited

Map a subentity to an index.

The result of calling this method with an entity that is not in the index set is undefined.

Template Parameters

cc	codimension of the entity

Parameters

[in]	e	reference to codimension cc entity
[in]	i	number subentity of e within the codimension
[in]	codim	codimension of the subentity we're interested in (must satisfy cc <= codim <= dimension)

Returns

An index in the range 0 ... Max number of entities in set - 1.
