Detailed Description

template<typename Grid>
class Dune::YaspPersistentContainerIndex< Grid >

implement a consecutive index for all entities of given codim of a YaspGrid

this class behaves similar to an IndexSet

to make this work for a persistent vector we have to implement...

 indexSet.size( codim )
 indexSet.index( entity );
 indexSet.subIndex( entity, subEntity, codimension() );

Member Typedef Documentation

IndexType

template<typename Grid >

typedef std::size_t Dune::YaspPersistentContainerIndex< Grid >::IndexType

The type used for the indices.

Member Function Documentation

index()

template<typename Grid >

template<class Entity >

IndexType Dune::YaspPersistentContainerIndex< Grid >::index ( const Entity &  e ) const

inline

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.

References Dune::Entity< cd, dim, GridImp, EntityImp >::codimension, and Dune::Entity< cd, dim, GridImp, EntityImp >::level().

size()

template<typename Grid >

std::size_t Dune::YaspPersistentContainerIndex< Grid >::size ( int  codim ) const

inline

Return total number of entities of given geometry type in entity set \(E\).

Parameters

[in]

type

A valid geometry type.

Returns

number of entities.

References Dune::Grid< dim, dimworld, ct, GridFamily >::size().

subIndex()

template<typename Grid >

template<class Entity >

IndexType Dune::YaspPersistentContainerIndex< Grid >::subIndex ( const Entity &  e, int  i, unsigned int  codim  ) const

inline

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

Note

The parameter codim denotes the codimension with respect to the grid, i.e., it must satisfy cc <= codim <= dimension.

Returns

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