Interface for calculating the size of a function space for a grid on a specified level. Furthermore the local to global mapping of dof number is done. Also during grid adaptation this mapper knows about old and new indices of entities.

template<class DofMapperTraits>
template<class Functor >
map each local DoF number to a global key
- Parameters
-
[in] | element | element, the DoFs belong to |
[in] | f | functor to call for each DoF |
The functor has to be a copyable object satisfying the following interface:
struct Functor
{
template< class GlobalKey >
void operator() ( const int localDoF, const GlobalKey &globalDoF );
};
For each DoF to be mapped, this method will call the application operator once.
- Note
- There is no guarantee on the order, in which the functor is applied.
-
The global key has to be compatible with the Dof storage.

obtain number of DoFs actually belonging to an entity
In contrast to numDofs, this method returns the number of DoFs actually associated with an entity (usually a subentity). We have the following relation for an entity
of codimension 0:
where
denotes the subentity relation.
- Parameters
-
[in] | entity | entity of codimension |
- Returns
- number of DoFs on the entity
