Detailed Description

template<int dim, int spacedim = dim>
class parallel::DistributedTriangulationBase< dim, spacedim >

A base class for distributed triangulations, i.e., triangulations that do not store all cells on all processors. This implies that not every detail of a triangulation may be known on each processor. In particular, you have to expect that triangulations of classes derived from this one only store some of the active cells (namely, the locally owned cells), along with ghost cells and possibly artificial cells. In contrast to the classes derived from parallel::TriangulationBase, it is certain that the classes derived from the current class will not store the entire triangulation as long as it has a large enough number of cells. (The difference to parallel::TriangulationBase is that the parallel::shared::Triangulation is derived from parallel::TriangulationBase, but not from the current class.) The distinction is not large in practice: Everything that is difficult for parallel distributed triangulation is generally also difficult for any other kind of parallel triangulation classes; however, this intermediate base class allows to further differentiate between the different kinds of classes providing parallel mesh functionality.

This class can, then, be used to test whether a pointer or reference to a triangulation object refers to any kind of parallel triangulation, or whether the triangulation is in fact parallel distributed. In other words, one could write a function like this:

template <int dim, int spacedim>
bool
is_parallel_distributed(const ::Triangulation<dim,spacedim> &tria)
{
  if(dynamic_cast<const
                  parallel::DistributedTriangulationBase<dim,spacedim>*>
                 (&tria)
     != nullptr)
    return true;
  else
    return false;
}
