Detailed Description

template<class GridImp, bool isLeafIndexSet>
class Dune::YaspIndexSet< GridImp, isLeafIndexSet >

Implementation of Level- and LeafIndexSets for YaspGrid.

Template Parameters

GridImp	The YaspGrid class we are an index set for
isLeafIndexSet	false: class functions as level index set, true: class functions as leaf index set

Member Function Documentation

contains()

bool Dune::IndexSet< GridImp, YaspIndexSet< GridImp, isLeafIndexSet > , unsigned int , std::array< GeometryType, 1 > >::contains ( const Entity &  e ) const

inlineinherited

Return true if the given entity is contained in \(E\).

Note

If the input element e is not an element of the grid, then the result of contains() is undefined.

index() [1/2]

IndexType Dune::IndexSet< GridImp, YaspIndexSet< GridImp, isLeafIndexSet > , unsigned int , std::array< GeometryType, 1 > >::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, YaspIndexSet< GridImp, isLeafIndexSet > , unsigned int , std::array< GeometryType, 1 > >::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]

template<class GridImp , bool isLeafIndexSet>

template<class Entity >

IndexType Dune::IndexSet< GridImp, IndexSetImp, IndexTypeImp, TypesImp >::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.

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

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.

subIndex() [2/2]

template<class GridImp , bool isLeafIndexSet>

template<int cc>

IndexType Dune::IndexSet< GridImp, IndexSetImp, IndexTypeImp, TypesImp >::subIndex ( const typename Traits::template Codim< cc >::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.

types()

Types Dune::IndexSet< GridImp, YaspIndexSet< GridImp, isLeafIndexSet > , unsigned int , std::array< GeometryType, 1 > >::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.
