Detailed Description
class Dune::Fem::DofMapper< DofMapperTraits >
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.
Member Function Documentation
◆ contains()
|
inline |
returns true if DoFs for given codimension exist
- Parameters
-
[in] codim codimension to check
- Returns
- true if DoFs for codimension exist
◆ mapEach()
|
inline |
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:
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.

◆ mapEachEntityDof()
|
inline |
map each local DoF number to a global key
- Parameters
-
[in] entity entity, the DoFs belong to [in] f functor to call for each DoF
The functor has to be a copyable object satisfying the following interface:
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.

◆ numDofs()
|
inline |
obtain number of DoFs on an entity
- Parameters
-
[in] element entity of codimension 0
- Returns
- number of DoFs on the entity
◆ numEntityDofs()
|
inline |
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 \(E\) of codimension 0:
\[ \mathrm{numDofs}( E ) = \sum_{e \subset E} \mathrm{numEntityDofs}( e ), \]
where \(\subset\) denotes the subentity relation.
- Parameters
-
[in] entity entity of codimension
- Returns
- number of DoFs on the entity
◆ update()
|
inline |
update DoF mapping after grid modification
- Note
- This method may not have any semantic side effects and may may be called arbitrarily often.
- If the update is expensive, implementors might choose to check the sequence number of the underlying grid part.
