Known subclasses: twisted.words.protocols.jabber.xmlstream.XmlStreamServerFactory, twisted.words.xish.xmlstream.XmlStreamFactoryMixin
XmlStream factory mixin to install bootstrap event observers.
This mixin is for factories providing IProtocolFactory
to make sure bootstrap event observers are set up on protocols, before
incoming data is processed. Such protocols typically derive from utility.EventDispatcher
,
like XmlStream
.
You can set up bootstrap event observers using
addBootstrap
. The event
and fn
parameters correspond with the event
and
observerfn
arguments to utility.EventDispatcher.addObserver
.
