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

Referenced by Dune::DefaultIndexSet< GridImp, IteratorImp >::DefaultIndexSet().

◆ contains()

bool Dune::IndexSet< GridImp, DefaultIndexSet< GridImp, IteratorImp > , unsigned int , std::vector< GeometryType > >::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, DefaultIndexSet< GridImp, IteratorImp > , unsigned int , std::vector< GeometryType > >::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 , std::vector< GeometryType > >::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 , std::vector< GeometryType > >::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

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() [2/3]

template<class GridImp , class IteratorImp >

template<int cc>

IndexType Dune::DefaultIndexSet< GridImp, IteratorImp >::subIndex	(	const typename std::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 , std::vector< GeometryType > >::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

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.
