Detailed Description

template<int dim, int spacedim = dim>
class hp::MappingCollection< dim, spacedim >

This class implements a collection of mapping objects in the same way as the hp::FECollection implements a collection of finite element classes.

It implements the concepts stated in the hp-Collections module described in the doxygen documentation.

Although it is recommended to supply an appropriate mapping for each finite element kind used in a hp-computation, the MappingCollection class implements a conversion constructor from a single mapping. Therefore it is possible to offer only a single mapping to the hp::FEValues class instead of a hp::MappingCollection. This is for the convenience of the user, as many simple geometries do not require different mappings along the boundary to achieve optimal convergence rates. Hence providing a single mapping object will usually suffice. See the hp::FEValues class for the rules which mapping will be selected for a given cell.

Constructor & Destructor Documentation

◆ MappingCollection() [1/5]

template<int dim, int spacedim = dim>
hp::MappingCollection< dim, spacedim >::MappingCollection ( )
default

Default constructor. Leads to an empty collection that can later be filled using push_back().

◆ MappingCollection() [2/5]

template<int dim, int spacedim>
hp::MappingCollection< dim, spacedim >::MappingCollection ( const Mapping< dim, spacedim > &  mapping)
explicit

Conversion constructor. This constructor creates a MappingCollection from a single mapping. More mappings can be added with push_back(), if desired, though it would probably be clearer to add all mappings the same way.

Definition at line 27 of file mapping_collection.cc.

◆ MappingCollection() [3/5]

template<int dim, int spacedim>
template<class... MappingTypes>
hp::MappingCollection< dim, spacedim >::MappingCollection ( const MappingTypes &...  mappings)
explicit

Constructor. This constructor creates a MappingCollection from one or more mapping objects passed to the constructor. For this call to be valid, all arguments need to be of types derived from class Mapping<dim,spacedim>.

Definition at line 158 of file mapping_collection.h.

◆ MappingCollection() [4/5]

template<int dim, int spacedim>
hp::MappingCollection< dim, spacedim >::MappingCollection ( const MappingCollection< dim, spacedim > &  mapping_collection)

Copy constructor.

Definition at line 36 of file mapping_collection.cc.

◆ MappingCollection() [5/5]

template<int dim, int spacedim = dim>
hp::MappingCollection< dim, spacedim >::MappingCollection ( MappingCollection< dim, spacedim > &&  ) const &
defaultnoexcept

Move constructor.

Note
The implementation of standard datatypes may change with different libraries, so their move members may or may not be flagged non-throwing. We need to explicitly set the noexcept specifier according to its member variables to still get the performance benefits (and to satisfy clang-tidy).

Member Function Documentation

◆ operator=()

template<int dim, int spacedim = dim>
MappingCollection< dim, spacedim > & hp::MappingCollection< dim, spacedim >::operator= ( MappingCollection< dim, spacedim > &&  )
default

Move assignment operator.

◆ push_back() [1/2]

template<int dim, int spacedim>
void hp::MappingCollection< dim, spacedim >::push_back ( const Mapping< dim, spacedim > &  new_mapping)

Add a new mapping to the MappingCollection. Generally, you will want to use the same order for mappings as for the elements of the hp::FECollection object you use. However, the same considerations as discussed with the hp::QCollection::push_back() function also apply in the current context.

This class creates a copy of the given mapping object, i.e., you can do things like push_back(MappingQ<dim>(3));. The internal copy is later destroyed by this object upon destruction of the entire collection.

Definition at line 47 of file mapping_collection.cc.

◆ push_back() [2/2]

template<typename T >
void hp::Collection< T >::push_back ( const std::shared_ptr< const T > &  new_entry)
inherited

Add a new object.

Definition at line 255 of file collection.h.

◆ operator[]()

template<typename T >
const T & hp::Collection< T >::operator[] ( const unsigned int  index) const
inlineinherited

Return the object which was specified by the user for the active FE index which is provided as a parameter to this method.

Precondition
index must be between zero and the number of elements of the collection.

Definition at line 273 of file collection.h.

◆ size()

template<typename T >
unsigned int hp::Collection< T >::size
inlineinherited

Return the number of objects stored in this container.

Definition at line 264 of file collection.h.

◆ memory_consumption()

template<typename T >
std::size_t hp::Collection< T >::memory_consumption
inherited

Determine an estimate for the memory consumption (in bytes) of this object.

Definition at line 246 of file collection.h.

◆ begin()

template<typename T >
CollectionIterator< T > hp::Collection< T >::begin
inherited
Returns
An iterator pointing to the beginning of the underlying data (const version).

Definition at line 283 of file collection.h.

◆ end()

template<typename T >
CollectionIterator< T > hp::Collection< T >::end
inherited
Returns
An iterator pointing to the end of the underlying data (const version).

Definition at line 292 of file collection.h.

◆ entries

template<typename T >
std::vector<std::shared_ptr<const T> > hp::Collection< T >::entries
