- """Represents a list of notmuch messages
-
- This object provides an iterator over a list of notmuch messages
- (Technically, it provides a wrapper for the underlying
- *notmuch_messages_t* structure). 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 messages, and a subsequent iteration attempt
- will raise a :exc:`NotmuchError` STATUS.NOT_INITIALIZED. Also
- note, that any function that uses iteration will also
- exhaust the messages. So both::
-
- for msg in msgs: print msg
-
- as well as::
-
- number_of_msgs = len(msgs)
-
- will "exhaust" the Messages. If you need to re-iterate over a list of
- messages you will need to retrieve a new :class:`Messages` object.
-
- Things are not as bad as it seems though, you can store and reuse
- the single Message objects as often as you want as long as you
- keep the parent Messages object around. (Recall that due to
- hierarchical memory allocation, all derived Message objects will
- be invalid when we delete the parent Messages() object, even if it
- was already "exhausted".) So this works::
-
- db = Database()
- msgs = Query(db,'').search_messages() #get a Messages() object
- msglist = []
- for m in msgs:
- msglist.append(m)
-
- # msgs is "exhausted" now and even len(msgs) will raise an exception.
- # However it will be kept around until all retrieved Message() objects are
- # also deleted. If you did e.g. an explicit del(msgs) here, the
- # following lines would fail.
-
- # You can reiterate over *msglist* however as often as you want.
- # It is simply a list with Message objects.
