To whom it may concern,
I try to generate a self-defined event in Ryu. What I have done shows
below,
1. define a xxx_event.py and define a EventXXXX in this file.
2. In a Ryu app, import xxx_event. Call the
self.send_event_to_observers(ev, self.state)
3. In another Ryu app, decorated a method by
@set_ev_handler(xxx_event.EventXXXX, state)
However, I run the apps and return nothing.
I really generate a event which defined by me, and call the
method:send_event_to_observers.
I found that the observers of my event is empty, so the event can't be
pushed in the Queue.
How should I do to register the observer?
If I add the code below to call handles, the event will be handled,
because I handle the event directly.
dispatchers = lambda x: x.callers[ev.__class__].dispatchers
handlers = [handler for handler in
self.oxp_brick.get_handlers(ev) if
MAIN_DISPATCHER in dispatchers(handler)]
for handler in handlers:
handler(ev)
Thanks for your time.
I look forward to your reply.
Best Regards.
