Observer Design Pattern for python gevent coroutine package (Python)

2010-12-08T08:33:30-08:00

Python recipe 577491 by Andrey Nikishaev (event, gevent, observer, python).

This is simple implementation of the observer design pattern. Acting as a registration hub, it fires events when requested. Also i have gevent.Timeout like interface in situations when you need to run event-method in the same greenlet. Example:

e = Observer()
ev = e.wait('kill')
try:
    gevent.sleep(3)
except FiredEvent:
    print 'Fired!'
else:
    print 'Not Fired!'
finally:
    ev.cancel()

But rememeber, if you are using subscribe method, event-method will be executed in another greenlet.

Flexible observer pattern implementation (Python)

2012-12-06T19:23:11-08:00

Python recipe 576962 by Glenn Eychaner (event, observer, pattern, publish, subscribe, threadsafe). Revision 16.

A simple, flexible, general-purpose observer pattern.

Observers can be callable objects or objects with a particular named method (handle_notify() by default). Events can be any object, and observers can select which events they are interested in receiving. Support for a number of different types of lightweight event objects is included.
