NOTE: if you use this method to get the iterator, you
must get sure the iterator is disposed (@see
Disposable.dispose()
) in any case, even if an error occurs
while getting the data. It is recommended to use the accept
methods instead, which handle everything for you.
Take into account the accept methods may use a fast iterator to
get the DynObjects.
