class Dune::PDELab::GFSDataHandle< GFS, V, GatherScatter, CommunicationDescriptor >
Implement a data handle with a grid function space.
- Template Parameters
-
GFS | a grid function space |
V | a vector container associated with the GFS |
GatherScatter | gather/scatter methods with argumemts buffer, and data |
CommunicationDescriptor | A descriptor for the communication structure |
