I ran into this too, but have had no trouble 'converting' to new style classes by just adding "object" to the superclass list. Anyone have reasons why we can't do that?<br><br>-Andy Fundinger<br><br>

I hope this is the correct place for this question.<br><br>I was trying to create a little customized task that sends a (ping)<br>message to the clients every X seconds. Because I needed some extra<br>bookkeeping, I implemented it as a class instance with a __call__
<br>method, that is passed to the LoopingCall.<br><br>However, I also wanted to automatically start the task on init, so I<br>thought - it makes a lot of sense to simply Inherit it, call its<br>constructor and pass self as the parameter. It was then I realized
<br>that the classes in twisted are old-style, when my super() call didn't<br>work.<br><br>Is there any practicular reason for that? Am I wrong to try inherit<br>the Looping Call ? Basically my code looks like :<br><br>
class SillyPinger(object):<br> def __init__(self, factory):<br> self.factory = factory<br> self.pingTargets = {}<br><br> pingTask = task.LoopingCall(self)<br> pingTask.start
(5.0)<br><br> def __call__(self):<br> # do stuff<br> pass<br><br><br>while I'd like to be doing:<br><br>class SillyPinger(task.LoopingCall):<br> def __init__(self, factory):<br> super(SillyPinger, self).__init__(self)
<br><br> self.factory = factory<br> self.pingTargets = {}<br><br> self.start(5.0) # get value from .ini here<br><br><br>Should I just switch to calling the LoopingCall constructor in the old
<br>way? I'm not sure I'd like to do that, even if only for consistency<br>reasons.<br><br>_______________________________________________<br>Twisted-Python mailing list<br><a href="mailto:Twisted-Python@twistedmatrix.com">
