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.
hp::MappingCollection< dim, spacedim >::MappingCollection | ( | ) |
Default constructor. Leads to an empty collection that can later be filled using push_back().
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.
hp::MappingCollection< dim, spacedim >::MappingCollection | ( | const MappingCollection< dim, spacedim > & | mapping_collection | ) |
Copy constructor.
void hp::MappingCollection< dim, spacedim >::push_back | ( | const Mapping< dim, spacedim > & | new_mapping | ) |
Adds a new mapping to the MappingCollection. The mappings have to be added in the order of the active_fe_indices. Thus the reference to the mapping object for active_fe_index 0 has to be added first, followed by the mapping object for active_fe_index 1.
const Mapping< dim, spacedim > & hp::MappingCollection< dim, spacedim >::operator[] | ( | const unsigned int | index | ) | const [inline] |
Returns the mapping object which was specified by the user for the active_fe_index which is provided as a parameter to this method.
index
must be between zero and the number of elements of the collection. References Assert, and hp::MappingCollection< dim, spacedim >::mappings.
unsigned int hp::MappingCollection< dim, spacedim >::size | ( | ) | const [inline] |
Returns the number of mapping objects stored in this container.
References hp::MappingCollection< dim, spacedim >::mappings.
unsigned int hp::MappingCollection< dim, spacedim >::memory_consumption | ( | ) | const |
Determine an estimate for the memory consumption (in bytes) of this object.
std::vector<std_cxx1x::shared_ptr<const Mapping<dim,spacedim> > > hp::MappingCollection< dim, spacedim >::mappings [private] |
The real container, which stores pointers to the different Mapping objects.
