Callbacks

twisted invoces callbacks just by invocing the function of the class implementing the Protocol (i.e. IRCClient). we need to run a lot of plugins, so our structure is a bit more complicated.

we implement the twisted-callbacks, and run _apirunner(“callback”, {'argument': argument}).

_apirunner looks into self.callbacks, which is a dict {'callback': [(plugininstance, priority)]}

the list [(plugin, priority)] is sorted by priority, so the most important callbacks (rarely used, but needed i.e for ircServer) are executed first.

the pluginSupport.callback list is filled on startPlugin with all plugin-functions, which have is_callback set. use pluginSupport.decorators.callback to set this statically. if you need to register callbacks dynamic, pluginSupport has registerCallback and unregisterCallback.
