Detailed Description

template<int dim, int q_dim, class FEValuesType>
class internal::hp::FEValuesBase< dim, q_dim, FEValuesType >

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 & Destructor Documentation

FEValuesBase() [1/2]

template<int dim, int q_dim, class FEValuesType >

internal::hp::FEValuesBase< dim, q_dim, FEValuesType >::FEValuesBase	(	const ::hp::MappingCollection< dim, FEValuesType::space_dimension > &	mapping_collection,
		const ::hp::FECollection< dim, FEValuesType::space_dimension > &	fe_collection,
		const ::hp::QCollection< q_dim > &	q_collection,
		const ::UpdateFlags	update_flags
	)

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

FEValuesBase() [2/2]

template<int dim, int q_dim, class FEValuesType >

FEValuesBase< dim, q_dim, FEValuesType >::FEValuesBase	(	const ::hp::FECollection< dim, FEValuesType::space_dimension > &	fe_collection,
		const ::hp::QCollection< q_dim > &	q_collection,
		const UpdateFlags	update_flags
	)

Constructor. This constructor is equivalent to the other one except that it makes the object use a \(Q_1\) mapping (i.e., an object of type MappingQGeneric(1)) implicitly.

get_update_flags()

get_present_fe_values()

template<int dim, int q_dim, class FEValuesType >

const FEValuesType & FEValuesBase< dim, q_dim, FEValuesType >::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.

Definition at line 613 of file fe_values.h.

select_fe_values()

template<int dim, int q_dim, class FEValuesType >

FEValuesType & FEValuesBase< dim, q_dim, FEValuesType >::select_fe_values ( const unsigned int  fe_index, const unsigned int  mapping_index, const unsigned int  q_index  )

protected

Select a FEValues object suitable for the given FE, quadrature, and mapping indices. If such an object doesn't yet exist, create one.

The function returns a writable reference so that derived classes can also reinit() the selected FEValues object.

fe_values_table

template<int dim, int q_dim, class FEValuesType >

::Table<3, std::shared_ptr<FEValuesType> > internal::hp::FEValuesBase< dim, q_dim, FEValuesType >::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().
