-class Threads(object):
- """Represents a list of notmuch threads
-
- This object provides an iterator over a list of notmuch threads
- (Technically, it provides a wrapper for the underlying
- *notmuch_threads_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 threads, 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 thread in threads: print thread
-
- as well as::
-
- number_of_msgs = len(threads)
-
- will "exhaust" the threads. If you need to re-iterate over a list of
- messages you will need to retrieve a new :class:`Threads` object.
-
- Things are not as bad as it seems though, you can store and reuse
- the single Thread objects as often as you want as long as you
- keep the parent Threads object around. (Recall that due to
- hierarchical memory allocation, all derived Threads objects will
- be invalid when we delete the parent Threads() object, even if it
- was already "exhausted".) So this works::
-
- db = Database()
- threads = Query(db,'').search_threads() #get a Threads() object
- threadlist = []
- for thread in threads:
- threadlist.append(thread)
-
- # threads is "exhausted" now and even len(threads) will raise an
- # exception.
- # However it will be kept around until all retrieved Thread() objects are
- # also deleted. If you did e.g. an explicit del(threads) here, the
- # following lines would fail.
-
- # You can reiterate over *threadlist* however as often as you want.
- # It is simply a list with Thread objects.
-
- print (threadlist[0].get_thread_id())
- print (threadlist[1].get_thread_id())
- print (threadlist[0].get_total_messages())
