Detailed Description

template<int dim, int dimworld, ALU2DSPACE ElementType eltype>
class Dune::ALU2dGridHierarchicIndexSet< dim, dimworld, eltype >

hierarchic index set of ALU2dGrid

Member Function Documentation

index()

IndexType Dune::IndexSet< ALU2dGrid< dim, dimworld, eltype > , ALU2dGridHierarchicIndexSet< dim, dimworld, eltype > , 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<int dim, int dimworld, ALU2DSPACE ElementType eltype>

int Dune::ALU2dGridHierarchicIndexSet< dim, dimworld, eltype >::size ( GeometryType  type ) const

inline

return size of indexset, i.e. maxindex+1 for given type, if type is not exisiting within grid 0 is returned

References Dune::GeometryType::dim(), Dune::ALU2dGrid< dim, dimworld, eltype >::geomTypes(), and Dune::ALU2dGrid< dim, dimworld, eltype >::hierSetSize().

subIndex() [1/2]

IndexType Dune::IndexSet< ALU2dGrid< dim, dimworld, eltype > , ALU2dGridHierarchicIndexSet< dim, dimworld, eltype > , 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() [2/2]

IndexType Dune::IndexSet< ALU2dGrid< dim, dimworld, eltype > , ALU2dGridHierarchicIndexSet< dim, dimworld, eltype > , 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.

types()

Types Dune::IndexSet< ALU2dGrid< dim, dimworld, eltype > , ALU2dGridHierarchicIndexSet< dim, dimworld, eltype > , int , TypesImp >::types ( int  codim ) const

inlineinherited

obtain all geometry types of entities in domain

This method returns an iterator range (something that behaves like Dune::IteratorRange) visiting all geometry types of codimension codim in the domain of the index map exactly once. The iterator must implement the concept of a forward iterator (in the sense of the STL). The elements in the iterator range are required to be of type Dune::GeometryType.

Parameters

[in]

codim

a valid codimension

Returns

iterator range over Const reference to a vector of geometry types.
