DOLFIN

replacement for boost::unordered_set<std::size_t> DofMap::dofs()?

Asked by Cian Wilson

Hi,

Just upgrading my code to the latest dolfin trunk after a few weeks. It looks like r7455.1.1 ("Some dofmap simplifications") removed boost::unordered_set<std::size_t> DofMap::dofs() const. Is there a new recommended way of getting something similar or should I just implement a loop over the cells and construct the set myself?

Many thanks,
Cian

You can use

    GenericDofMap::ownership_range()

to get the range for the 'owned' dofs, and

    Generic::off_process_owner

to get the dofs that appear in the local dofmap but are not owned.

Using these two functions will be much more efficient than the old
GenericDofMap::dofs().
