internal::ComponentDoFs< dim, spacedim > Class Template Reference

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

Detailed Description

template<int dim, int spacedim = dim>
class internal::ComponentDoFs< dim, spacedim >

Per-component enumeration of a FiniteElement suitable for use with MappingFEField's DoFs.

MappingFEField can use both primitive finite elements (i.e., elements which are nonzero in exactly one component) as well as a ComponentMask to select components from a FiniteElement with more than spacedim components. This class computes, from both the FiniteElement and ComponentMask, the nonzero DoFs for each selected component.

Note

this class is not an internal class of MappingFEField to make it easier to use in maybe_update_Jacobians() etc.
