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.

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

Copy constructor.

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 253 of file q_collection.h.

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>.

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.

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

must be between zero and the number of elements of the collection. Definition at line 226 of file q_collection.h.

Equality comparison operator. All stored Quadrature objects are compared in order.

Return the number of quadrature pointers stored in this object.
Definition at line 200 of file q_collection.h.
|
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.

Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.

Read or write the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.
This function does not actually serialize any of the member variables of this class. The reason is that what this class stores is only who subscribes to this object, but who does so at the time of storing the contents of this object does not necessarily have anything to do with who subscribes to the object when it is restored. Consequently, we do not want to overwrite the subscribers at the time of restoring, and then there is no reason to write the subscribers out in the first place.
