Detailed Description

template<typename G>
class Dune::LeafMultipleCodimMultipleGeomTypeMapper< G >

Multiple codim and multiple geometry type mapper for leaf entities.

This mapper uses all leaf entities of a certain codimension as its entity set.

Deprecated:
Use MultipleCodimMultipleGeomTypeMapper instead
Template Parameters
GA Dune grid type.

Member Typedef Documentation

◆ size_type

using Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::size_type = decltype(std::declval<typename GV::IndexSet>().size(0))
inherited

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.

Member Function Documentation

◆ contains() [1/3]

bool Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::contains ( const EntityType &  e,
Index result 
) const
inlineinherited

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

Parameters
eReference to entity
resultinteger 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 , MultipleCodimMultipleGeomTypeMapper< G::LeafGridView > , 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]eReference to codim 0 entity
[in]isubentity number
[in]ccsubentity codim
[out]resultFilled with array index if entity is contained
Returns
true if entity is in entity set of the mapper

◆ contains() [3/3]

bool Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::contains ( const typename GV::template Codim< 0 >::Entity &  e,
int  i,
int  cc,
Index result 
) const
inlineinherited

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

Parameters
eReference to codim 0 entity
isubentity number
ccsubentity codim
resultinteger reference where corresponding index is stored if true
Returns
true if entity is in entity set of the mapper

◆ index()

Index Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::index ( const EntityType &  e) const
inlineinherited

Map entity to starting index in array for dof block.

Template Parameters
EntityType
Parameters
eReference to codim EntityType entity.
Returns
An index in the range 0 ... (Max number of entities in set)*blockSize - 1.

◆ indices() [1/2]

IntegralRange< Index > Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::indices ( const EntityType &  e) const
inlineinherited

Returns a pair with the starting point in the dof vector and the number of degrees of freedom if the entity is contained in the index set otherwise {0,0} is returned.

Parameters
eReference to entity
resultinteger reference to the start of the block
Returns
pair with first entry equal to index for that entity and the second entry the number of degrees of freedom (zero if entity is not in entity set of the mapper)

◆ indices() [2/2]

IntegralRange< Index > Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::indices ( const typename GV::template Codim< 0 >::Entity &  e,
int  i,
int  cc 
) const
inlineinherited

Returns a pair with the starting point in the dof vector and the number of degrees of freedom if the entity is contained in the index set otherwise {0,0} is returned.

Parameters
eReference to codim 0 entity
isubentity number
ccsubentity codim
resultinteger reference to the start of the block
Returns
pair with first entry equal to index for that entity and the second entry the number of degrees of freedom (zero if sub entity is not in entity set of the mapper)

◆ size()

size_type Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::size ( ) const
inlineinherited

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 , MultipleCodimMultipleGeomTypeMapper< G::LeafGridView > , 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
eReference to codim 0 entity.
iNumber of codim cc subentity of e, where cc is the template parameter of the function.
codimcodimension of subentity of e
Returns
An index in the range 0 ... Max number of entities in set - 1.

◆ subIndex() [2/2]

Index Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::subIndex ( const typename GV::template Codim< 0 >::Entity &  e,
int  i,
unsigned int  codim 
) const
inlineinherited

Map subentity of codim 0 entity to starting index in array for dof block.

Parameters
eReference to codim 0 entity.
iNumber of subentity of e
codimCodimension of the subentity
Returns
An index in the range 0 ... Max number of entities in set - 1.

◆ update() [1/3]

template<typename G >
void Dune::LeafMultipleCodimMultipleGeomTypeMapper< G >::update ( )
inline

Recalculates indices after grid adaptation.

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

◆ update() [2/3]

void Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::update ( const G::LeafGridView &  gridView)
inlineinherited

Recalculates indices after grid adaptation.

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

◆ update() [3/3]

void Dune::MultipleCodimMultipleGeomTypeMapper< G::LeafGridView >::update ( G::LeafGridView &&  gridView)
inlineinherited

Recalculates indices after grid adaptation.

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