Detailed Description

template<int dim>
class hp::QCollection< dim >

This class implements a collection of quadrature 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.

Constructor & Destructor Documentation

QCollection() [1/3]

template<int dim>

hp::QCollection< dim >::QCollection ( )

default

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

QCollection() [2/3]

template<int dim>

hp::QCollection< dim >::QCollection ( const Quadrature< dim > &  quadrature )

inlineexplicit

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

Definition at line 204 of file q_collection.h.

QCollection() [3/3]

template<int dim>

template<class... QTypes>

hp::QCollection< dim >::QCollection ( const QTypes &...  quadrature_objects )

explicit

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

Definition at line 150 of file q_collection.h.

Member Function Documentation

push_back()

template<int dim>

void hp::QCollection< dim >::push_back ( const Quadrature< dim > &  new_quadrature )

inline

Add a new quadrature rule to the QCollection. In most cases, you will want to add quadrature rules in the same order as the elements were added to the hp::FECollection for which this quadrature rule collection is meant. If done this way, the hp::FEValues objects with which you will use both hp::FECollection and hp::QCollection objects will automatically choose corresponding elements and quadrature formulas. On the other hand, it is possible to use arbitrary combinations of elements and quadrature formulas in hp::FECollection and hp::QCollection objects when specifically specifying appropriate indices in calls to hp::FEValues::reinit() or hp::FEFaceValues::reinit(). In those cases, there need not be a correspondence between elements of the hp::FECollection and hp::QCollection objects; they need not even be of the same size in this case.

The same arguments about the order of elements of collections can, by the way, also be made about the elements of hp::MappingCollection objects.

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

Definition at line 221 of file q_collection.h.

operator[]()

template<int dim>

const Quadrature< dim > & hp::QCollection< dim >::operator[] ( const unsigned int  index ) const

inline

Return a reference to the quadrature rule specified by the argument.

Precondition

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

Definition at line 194 of file q_collection.h.

size()

template<int dim>

unsigned int hp::QCollection< dim >::size ( ) const

inline

Return the number of quadrature pointers stored in this object.

Definition at line 168 of file q_collection.h.

max_n_quadrature_points()

template<int dim>

unsigned int hp::QCollection< dim >::max_n_quadrature_points ( ) const

inline

Return the maximum number of quadrature points over all the elements of the collection. This is mostly useful to initialize arrays to allocate the maximum amount of memory that may be used when re-sizing later on to a articular quadrature formula from within this collection.

Definition at line 177 of file q_collection.h.

memory_consumption()

template<int dim>

std::size_t hp::QCollection< dim >::memory_consumption ( ) const

inline

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

Definition at line 213 of file q_collection.h.

Member Data Documentation

quadratures

template<int dim>

std::vector<std::shared_ptr<const Quadrature<dim> > > hp::QCollection< dim >::quadratures

private

The real container, which stores pointers to the different quadrature objects.
