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>

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.

Definition at line 50 of file fe_system.cc.

~InternalData()

template<int dim, int spacedim>

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

override

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

Definition at line 59 of file fe_system.cc.

set_fe_data()

template<int dim, int spacedim>

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

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

Definition at line 80 of file fe_system.cc.

get_fe_data()

template<int dim, int spacedim>

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.

Definition at line 69 of file fe_system.cc.

get_fe_output_object()

template<int dim, int spacedim>

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.

Definition at line 92 of file fe_system.cc.

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.

Definition at line 1222 of file fe_system.h.

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.
