- This object contains the Filenames iterator. The main function is
- as_generator() which will return a generator so we can do a Filenamesth an
- iterator over a list of notmuch filenames. Do note that the underlying
- library only provides a one-time iterator (it cannot reset the iterator to
- the start). Thus iterating over the function will "exhaust" the list of
- tags, and a subsequent iteration attempt will raise a
- :exc:`NotInitializedError`. Also note, that any function that uses
- iteration (nearly all) will also exhaust the tags. So both::
