Detailed Description

template<typename RankIndex>
class Dune::PDELab::DisjointPartitioningGatherScatter< RankIndex >

GatherScatter functor for creating a disjoint DOF partitioning.

This functor will associate each DOF with a unique rank, creating a nonoverlapping partitioning of the unknowns. The rank for a DOF is chosen by finding the lowest rank on which the associated grid entity belongs to either the interior or the border partition.

Note

In order to work correctly, the data handle must be communicated on the Dune::InteriorBorder_All_Interface and the result vector must be initialized with the MPI rank value.
