Base class for the hp::FE*Values
classes, storing the data that is common to them. The main task of this class is to provide a table where for every combination of finite element, mapping, and quadrature object from their corresponding collection objects there is a matching FEValues, FEFaceValues, or FESubfaceValues object. To make things more efficient, however, these FE*Values objects are only created once requested (lazy allocation).
The first template parameter denotes the space dimension we are in, the second the dimensionality of the object that we integrate on, i.e. for usual hp::FEValues
it is equal to the first one, while for face integration it is one less. The third template parameter indicates the type of underlying non-hp FE*Values base type, i.e. it could either be FEValues, FEFaceValues, or FESubfaceValues.

Constructor. Set the fields of this class to the values indicated by the parameters to the constructor.

Constructor. Set the fields of this class to the values indicated by the parameters to the constructor, and choose a MappingQ1
object for the mapping object.
const FEValues & FEValuesBase< dim, q_dim, FEValues >::get_present_fe_values | ( | ) | const [inline] |
Return a reference to the FEValues
object selected by the last call to select_fe_values(). select_fe_values() in turn is called when you called the reinit
function of the hp::FE*Values
class the last time.

A pointer to the collection of finite elements to be used.

A pointer to the collection of mappings to be used.
const ::hp::QCollection<q_dim> internal::hp::FEValuesBase< dim, q_dim, FEValues >::q_collection [protected] |
Copy of the quadrature collection object provided to the constructor.
Table<3,std_cxx1x::shared_ptr<FEValues> > internal::hp::FEValuesBase< dim, q_dim, FEValues >::fe_values_table [private] |
A table in which we store pointers to fe_values objects for different finite element, mapping, and quadrature objects from our collection. The first index indicates the index of the finite element within the fe_collection, the second the index of the mapping within the mapping collection, and the last one the index of the quadrature formula within the q_collection.
Initially, all entries have zero pointers, and we will allocate them lazily as needed in select_fe_values().
