class twisted.words.xish.xmlstream.BootstrapMixin: (source)
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.
