From c004f042f9976e90cfd42a0698ba83872fe00825 Mon Sep 17 00:00:00 2001 From: Lance Stout Date: Thu, 20 May 2010 23:17:22 +0800 Subject: [PATCH] Added del_event_handler to remove handler functions for a given event. All registered handlers for the event which use the given function will be removed. Using this method allows agents to reconfigure their behaviour on the fly without needing to add extra state information to event handling functions. --- sleekxmpp/basexmpp.py | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/sleekxmpp/basexmpp.py b/sleekxmpp/basexmpp.py index 13fe210..83431bd 100644 --- a/sleekxmpp/basexmpp.py +++ b/sleekxmpp/basexmpp.py @@ -185,6 +185,19 @@ class basexmpp(object): self.event_handlers[name] = [] self.event_handlers[name].append((pointer, threaded, disposable)) + def del_event_handler(self, name, pointer): + """Remove a handler for an event.""" + if not name in self.event_handlers: + return + + # Need to keep handlers that do not use + # the given function pointer + def filter_pointers(handler): + return handler[0] != pointer + + self.event_handlers[name] = filter(filter_pointers, + self.event_handlers[name]) + def event(self, name, eventdata = {}): # called on an event for handler in self.event_handlers.get(name, []): if handler[1]: #if threaded
