"""After instantiating Detector and adding individual detector coroutines, call
feed_input(obj, index) over and over until you are done. You should end with a
sentinal obj. Look in .matches to get the results.
Detectors should be implemented like:
def detector(data, obj):
next_obj = yield if_obj_was_okay
next_obj2 = yield if_next_obj_was_okay
return # returning means successful conclusion
# Add info to the data dict at any time
for checker, data in list(self._pending):
result = checker.send(obj)
except StopIteration:
# Success!
result = False
if not result:
self._pending.remove((checker, data))
for detector in self.detectors:
data = {"index": index, "detector": detector}
checker = detector(data, obj)
# Then we have to prime the checker...
result = next(checker)
if not result:
self._pending.append((checker, data))
