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.

| 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.
| FESystem< dim, spacedim >::InternalData::~InternalData | ( | ) |
Destructor. Deletes all InternalDatas whose pointers are stored by the base_fe_datas vector.
| void FESystem< dim, spacedim >::InternalData::set_fe_data | ( | const unsigned int | base_no, |
| typename FiniteElement< dim, spacedim >::InternalDataBase * | |||
| ) |
Gives write-access to the pointer to a InternalData of the base_noth base element.
| FiniteElement<dim,spacedim>::InternalDataBase& FESystem< dim, spacedim >::InternalData::get_fe_data | ( | const unsigned int | base_no ) | const |
Gives read-access to the pointer to a InternalData of the base_noth base element.
| void FESystem< dim, spacedim >::InternalData::set_fe_values_data | ( | const unsigned int | base_no, |
| FEValuesData< dim, spacedim > * | |||
| ) |
Gives write-access to the pointer to a FEValuesData for the base_noth base element.
| FEValuesData<dim,spacedim>& FESystem< dim, spacedim >::InternalData::get_fe_values_data | ( | const unsigned int | base_no ) | const |
Gives read-access to the pointer to a FEValuesData for the base_noth base element.
| void FESystem< dim, spacedim >::InternalData::delete_fe_values_data | ( | const unsigned int | base_no ) |
Deletes the FEValuesData the fe_datas[base_no] pointer is pointing to. Sets fe_datas[base_no] to zero.
This function is used to delete FEValuesData that are needed only on the first cell but not any more afterwards. This is the case for e.g. Lagrangian elements (see e.g. FE_Q classes).
| virtual void FESystem< dim, spacedim >::InternalData::clear_first_cell | ( | ) | [virtual] |
Set the first_cell flag to false. Used by the FEValues class to indicate that we have already done the work on the first cell.
In addition to calling the respective function of the base class, this function also calls the functions of the sub-data objects.
Reimplemented from Mapping< dim, spacedim >::InternalDataBase.
| bool FESystem< dim, spacedim >::InternalData::compute_hessians |
Flag indicating whether second derivatives shall be computed.

std::vector<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.

std::vector<FEValuesData<dim,spacedim> *> FESystem< dim, spacedim >::InternalData::base_fe_values_datas [private] |
Pointers to the FEValuesData objects that are given to the fill_fe_values function of the base elements. They are accessed to by the set_ and get_fe_values_data functions.
The size of this vector is set to n_base_elements by the InternalData constructor.
