I don't remember it and can't find it.
What I would like to do is
std::set<> foo = mesh.subdomain_ids()
or something like that.
I'd be a little scared of RVO not working in problems with large sets
of subdomains. Maybe
mesh.subdomain_ids(std::set<subdomain_id_type>& foo)
?
It appears that we basically build this internally to MeshBase::n_subdomains ()
and return its size, but I'd like the actual set.
Yeah; we ought to factor that out into a separate public method.
And replace the "unsigned int" there with "subdomain_id_type" while
we're at it.
