FESystem< dim, spacedim >::InternalData Class Reference

Detailed Description

template<int dim, int spacedim = dim>
class FESystem< dim, spacedim >::InternalData

Usually: Fields of cell-independent data.

However, here, this class does not itself store the data but only pointers to InternalData objects for each of the base elements.

Constructor & Destructor Documentation

InternalData()

template<int dim, int spacedim = dim>

FESystem< dim, spacedim >::InternalData::InternalData

(

const unsigned int

n_base_elements

)

Constructor. Is called by the get_data function. Sets the size of the base_fe_datas vector to n_base_elements.

~InternalData()

template<int dim, int spacedim = dim>

FESystem< dim, spacedim >::InternalData::~InternalData ( )

override

Destructor. Deletes all InternalDatas whose pointers are stored by the base_fe_datas vector.

Member Function Documentation

set_fe_data()

template<int dim, int spacedim = dim>

void FESystem< dim, spacedim >::InternalData::set_fe_data	(	const unsigned int	base_no,
		std::unique_ptr< typename FiniteElement< dim, spacedim >::InternalDataBase >	)

Give write-access to the pointer to a InternalData of the base_noth base element.

get_fe_data()

template<int dim, int spacedim = dim>

FiniteElement< dim, spacedim >::InternalDataBase & FESystem< dim, spacedim >::InternalData::get_fe_data

(

const unsigned int

base_no

)

const

Give read-access to the pointer to a InternalData of the base_noth base element.

get_fe_output_object()

template<int dim, int spacedim = dim>

internal::FEValuesImplementation::FiniteElementRelatedData< dim, spacedim > & FESystem< dim, spacedim >::InternalData::get_fe_output_object

(

const unsigned int

base_no

)

const

Give read-access to the pointer to an object to which into which the base_noth base element will write its output when calling FiniteElement::fill_fe_values() and similar functions.

memory_consumption()

template<int dim, int spacedim = dim>

virtual std::size_t FiniteElement< dim, spacedim >::InternalDataBase::memory_consumption ( ) const

virtualinherited

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

Member Data Documentation

base_fe_datas

template<int dim, int spacedim = dim>

std::vector< std::unique_ptr<typename FiniteElement<dim, spacedim>::InternalDataBase> > FESystem< dim, spacedim >::InternalData::base_fe_datas

private

Pointers to InternalData objects for each of the base elements. They are accessed to by the set_ and get_fe_data functions.

The size of this vector is set to n_base_elements by the InternalData constructor. It is filled by the get_data function. Note that since the data for each instance of a base class is necessarily the same, we only need as many of these objects as there are base elements, irrespective of their multiplicity.

base_fe_output_objects

template<int dim, int spacedim = dim>

std::vector< internal::FEValuesImplementation::FiniteElementRelatedData<dim, spacedim> > FESystem< dim, spacedim >::InternalData::base_fe_output_objects

mutableprivate

A collection of objects to which the base elements will write their output when we call FiniteElement::fill_fe_values() and related functions on them.

The size of this vector is set to n_base_elements by the InternalData constructor.

Definition at line 1323 of file fe_system.h.

update_each

template<int dim, int spacedim = dim>

UpdateFlags FiniteElement< dim, spacedim >::InternalDataBase::update_each

inherited

A set of update flags specifying the kind of information that an implementation of the FiniteElement interface needs to compute on each cell or face, i.e., in FiniteElement::fill_fe_values() and friends.

This set of flags is stored here by implementations of FiniteElement::get_data(), FiniteElement::get_face_data(), or FiniteElement::get_subface_data(), and is that subset of the update flags passed to those functions that require re-computation on every cell. (The subset of the flags corresponding to information that can be computed once and for all already at the time of the call to FiniteElement::get_data() – or an implementation of that interface – need not be stored here because it has already been taken care of.)
