My one-time classes usually have more than one method:
def query(self, domain_name, record_type, listener, xid = None):
...
client = self
class Operation:
def cancel(self):
if key in client.opmap and client.opmap[key] is self:
del client.opmap[key]
def callback():
client.log('CANCELED')
listener(client.CANCELED, None)
client.mux.schedule(callback)
def notify(self, verdict, records):
client.log('verdict = {}'.format(verdict))
listener(verdict, records)
operation = Operation()
self.opmap[key] = operation
