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. This version is usually not used directly but is used to implement versions for leafwise and levelwise entity sets.

Template Parameters

GV	A Dune grid view type
c	A valid codimension

Constructor & Destructor Documentation

template<typename GV, int c>

Dune::SingleCodimSingleGeomTypeMapper< GV, c >::SingleCodimSingleGeomTypeMapper

(

const GV &

gridView

)

Construct mapper from grid and one of its index sets.

Parameters

gridView

A Dune GridView object.

Member Function Documentation

template<typename GV , int c>

template<class EntityType >

bool Dune::SingleCodimSingleGeomTypeMapper< GV, c >::contains ( const EntityType &  e, int &  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

template<typename GV, int c>

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

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

template<typename GV , int c>

template<class EntityType >

int Dune::SingleCodimSingleGeomTypeMapper< GV, c >::map ( const EntityType &  e ) const

inline

Map entity to array index.

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.

template<typename GV, int c>

int Dune::SingleCodimSingleGeomTypeMapper< GV, c >::map ( 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.

int Dune::Mapper< GV::Grid , SingleCodimSingleGeomTypeMapper< GV, c > >::map ( const typename GV::Grid ::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.

template<typename GV , int c>

int 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.

template<typename GV, int c>

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

inline

Recalculates map after mesh adaptation.
