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() [1/4]

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() [2/4]

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() [3/4]

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() [4/4]

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 136 of file mapping_collection.h.

Member Function Documentation

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]

void hp::Collection< Mapping< dim, dim > >::push_back ( const std::shared_ptr< const Mapping< dim, dim > > &  new_entry )

inherited

Add a new object.

Definition at line 53 of file collection.h.

operator[]()

const Mapping< dim, dim > & hp::Collection< Mapping< dim, dim > >::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 62 of file collection.h.

size()

unsigned int hp::Collection< Mapping< dim, dim > >::size

inlineinherited

Return the number of objects stored in this container.

Definition at line 68 of file collection.h.

memory_consumption()

std::size_t hp::Collection< Mapping< dim, dim > >::memory_consumption

inherited

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

Definition at line 75 of file collection.h.
