I want to subclass an IMAP connection so that most of the
methods raise an exception if the returned status isn't 'OK'.
This works, but there's got to be a way to do it that doesn't
involve so much duplication:
class MyImap4_ssl(imaplib.IMAP4_SSL):
def login(*args):
s,r = imaplib.IMAP4_SSL.login(*args)
if s!='OK':
raise NotOK((s,r))
return r
def list(*args):
s,r = imaplib.IMAP4_SSL.list(*args)
if s!='OK':
raise NotOK((s,r))
return r
def search(*args):
s,r = imaplib.IMAP4_SSL.search(*args)
if s!='OK':
raise NotOK((s,r))
return r
[and so on for another dozen methods]
You could try something like (Untested!):
class Wrapper(object):
def __init__(self, func):
self.func = func
def __call__(*args, **kwargs):
self, args = args[0], args[1:]
s, r = self.func(*args)
if s != 'OK':
raise NotOK((s, r))
return r
for func_name in ['login', 'list', 'search']:
func = Wrapper(getattr(imaplib.IMAP4_SSL, func_name))
setattr(imaplib.IMAP4_SSL, func_name, func)
