Id Set Interface.
Definition: indexidset.hh:414
IdType subId(const typename remove_const< GridImp >::type::Traits::template Codim< 0 >::Entity &e, int i, unsigned int codim) const
Get id of subentity i of co-dimension codim of a co-dimension 0 entity.
Definition: indexidset.hh:441
IdType id(const Entity &e) const
Get id of an entity. This method is simpler to use than the one below.
Definition: indexidset.hh:421
Provides base classes for index and id sets.
