Detailed Description

template<typename GV, int c>
class Dune::SingleCodimSingleGeomTypeMapper< GV, c >

Implementation class for a single codim and single geometry type mapper.

In this implementation of a mapper the entity set used as domain for the map consists of the entities of a given codimension c for all entities in the given index set. The index set may only contain entities of a single geometry type, otherwise an exception is thrown.

Template Parameters

GV	A Dune grid view type
c	A valid codimension

Member Typedef Documentation

◆ Index

template<typename GV , int c>

typedef GV::IndexSet::IndexType Dune::SingleCodimSingleGeomTypeMapper< GV, c >::Index

Number type used for indices.

◆ size_type

template<typename GV , int c>

using Dune::SingleCodimSingleGeomTypeMapper< GV, c >::size_type = decltype(std::declval<typename GV::IndexSet>().size(0))

Number type used for the overall size (the return value of the 'size' method)

The type used here is set to be the corresponding type used by the GridView's index set.

Constructor & Destructor Documentation

◆ SingleCodimSingleGeomTypeMapper()

template<typename GV , int c>

Dune::SingleCodimSingleGeomTypeMapper< GV, c >::SingleCodimSingleGeomTypeMapper ( const GV & gridView )

inline

Construct mapper from grid and one of its index sets.

Parameters

gridView A Dune GridView object.

Member Function Documentation

◆ contains() [1/3]

template<typename GV , int c>

template<class EntityType >

bool Dune::SingleCodimSingleGeomTypeMapper< GV, c >::contains	(	const EntityType &	e,
		Index &	result
	)		const

inline

Returns true if the entity is contained in the index set.

Parameters

e	Reference to entity
result	integer reference where corresponding index is stored if true

Returns: true if entity is in entity set of the mapper

◆ contains() [2/3]

bool Dune::Mapper< GV::Grid , SingleCodimSingleGeomTypeMapper< GV, c > , GV::IndexSet::IndexType >::contains	(	const typename G::Traits::template Codim< 0 >::Entity &	e,
		int	i,
		int	cc,
		GV::IndexSet::IndexType &	result
	)		const

inlineinherited

Returns true if the subentity is contained in the index set and at the same time the array index is returned.

Parameters

[in]	e	Reference to codim 0 entity
[in]	i	subentity number
[in]	cc	subentity codim
[out]	result	Filled with array index if entity is contained

Returns: true if entity is in entity set of the mapper

◆ contains() [3/3]

template<typename GV , int c>

bool Dune::SingleCodimSingleGeomTypeMapper< GV, c >::contains	(	const typename GV::template Codim< 0 >::Entity &	e,
		int	i,
		int	cc,
		Index &	result
	)		const

inline

Returns true if the entity is contained in the index set.

Parameters

e	Reference to codim 0 entity
i	subentity number
cc	subentity codim
result	integer reference where corresponding index is stored if true

Returns: true if entity is in entity set of the mapper

◆ index()

template<typename GV , int c>

template<class EntityType >

Index Dune::SingleCodimSingleGeomTypeMapper< GV, c >::index ( const EntityType & e ) const

inline

Map entity to array index.

\param e Reference to codim cc entity, where cc is the template parameter of the function.
\return An index in the range 0 ... Max number of entities in set - 1.

◆ size()

template<typename GV , int c>

size_type Dune::SingleCodimSingleGeomTypeMapper< GV, c >::size ( ) const

inline

Return total number of entities in the entity set managed by the mapper.

This number can be used to allocate a vector of data elements associated with the entities of the set. In the parallel case this number is per process (i.e. it may be different in different processes).

Returns: Size of the entity set.

◆ subIndex() [1/2]

Index Dune::Mapper< GV::Grid , SingleCodimSingleGeomTypeMapper< GV, c > , GV::IndexSet::IndexType >::subIndex	(	const typename G::Traits::template Codim< 0 >::Entity &	e,
		int	i,
		unsigned int	codim
	)		const

inlineinherited

Map subentity i of codim cc of a codim 0 entity to array index.

Parameters

e	Reference to codim 0 entity.
i	Number of codim cc subentity of e, where cc is the template parameter of the function.
codim	codimension of subentity of e

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

◆ subIndex() [2/2]

template<typename GV , int c>

Index Dune::SingleCodimSingleGeomTypeMapper< GV, c >::subIndex	(	const typename GV::template Codim< 0 >::Entity &	e,
		int	i,
		unsigned int	codim
	)		const

inline

Map subentity of codim 0 entity to array index.

Parameters

e	Reference to codim 0 entity.
i	Number of the subentity of e, where cc is the template parameter of the function.
codim	Codimension of the subentity of e

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

◆ update() [1/4]

template<typename GV , int c>

void Dune::SingleCodimSingleGeomTypeMapper< GV, c >::update ( )

inline

Recalculates indices after grid adaptation.

◆ update() [2/4]

template<typename GV , int c>

void Dune::SingleCodimSingleGeomTypeMapper< GV, c >::update ( const GV & gridView )

inline

Recalculates indices after grid adaptation.

After grid adaptation you need to call this to update the stored gridview and recalculate the indices.

◆ update() [3/4]

void Dune::Mapper< GV::Grid , SingleCodimSingleGeomTypeMapper< GV, c > , GV::IndexSet::IndexType >::update ( GridView && gridView )

inlineinherited

Reinitialize mapper after grid has been modified.

◆ update() [4/4]

template<typename GV , int c>

void Dune::SingleCodimSingleGeomTypeMapper< GV, c >::update ( GV && gridView )

inline

Recalculates indices after grid adaptation.

After grid adaptation you need to call this to update the stored gridview and recalculate the indices.
