class Dune::SGridLevelIndexSet< GridImp >

implementation of index set

Member Function Documentation

index() [1/2]

IndexType Dune::IndexSet< GridImp, SGridLevelIndexSet< GridImp > , IndexTypeImp, 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, SGridLevelIndexSet< GridImp > , IndexTypeImp, 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.

subIndex() [1/2]

IndexType Dune::IndexSet< GridImp, SGridLevelIndexSet< GridImp > , IndexTypeImp, 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() [2/2]

IndexType Dune::IndexSet< GridImp, SGridLevelIndexSet< GridImp > , IndexTypeImp, 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.
