====== BigObject PolyDB::Cursor ======
//from application [[..:common|common]]//\\
\\
 Database cursor over the results of a query operation. Objects can be retrieved in a loop, fetching one at a time, or all at once.

  ? Example:
  :: Process results of a query in a loop
  :: <code perl> > for (my $cursor = $collection->find({}); $cursor->has_next; ) {
 >   my $object = $cursor->next;
 >   do_something($object);
 > }
</code>
  ::  Retrieve all objects at once
  :: <code perl> > @with_100_vertices = $collection->find({ N_VERTICES => 100 })->all;
</code>
