MappingP1< dim, spacedim >::InternalData Class Reference

#include <deal.II/fe/mapping_p1.h>

Detailed Description

template<int dim, int spacedim = dim>
class MappingP1< dim, spacedim >::InternalData

Storage for internal data of the mapping. See Mapping::InternalDataBase for an extensive description.

This includes data that is computed once when the object is created (in get_data()) as well as data the class wants to store from between the call to fill_fe_values(), fill_fe_face_values(), or fill_fe_subface_values() until possible later calls from the finite element to functions such as transform(). The latter class of member variables are marked as 'mutable'.

Member Function Documentation

reinit()

template<int dim, int spacedim>

void MappingP1< dim, spacedim >::InternalData::reinit ( const UpdateFlags update_flags, const Quadrature< dim > & quadrature )

overridevirtual

This function initializes the data fields related to evaluation of the mapping on cells, implemented by (derived) classes. This function is used both when setting up a field of this class for the first time or when a new Quadrature formula should be considered without creating an entirely new object. This is used when the number of evaluation points is different on each cell, e.g. when using FEPointEvaluation for handling particles or with certain non-matching problem settings.

Reimplemented from Mapping< dim, spacedim >::InternalDataBase.

memory_consumption()

template<int dim, int spacedim>

std::size_t MappingP1< dim, spacedim >::InternalData::memory_consumption ( ) const

overridevirtual

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

quadrature

template<int dim, int spacedim = dim>

Quadrature<dim> MappingP1< dim, spacedim >::InternalData::quadrature

Quadrature. May be an amalgamation of rules created by, e.g., QProjector::project_to_all_faces().

Definition at line 242 of file mapping_p1.h.

update_each

template<int dim, int spacedim = dim>

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

inherited

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

This set of flags is stored here by implementations of Mapping::get_data(), Mapping::get_face_data(), or Mapping::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 Mapping::get_data() – or an implementation of that interface – need not be stored here because it has already been taken care of.)
