Unlike C{proto_helpers}, this is no exception to the don't-use-it-outside-Twisted-we-won't-maintain-compatibility rule! @note: Maintainers be aware: things in this module should be gradually promoted to more full-featured test helpers and exposed as public API as your maintenance time permits. In order to be public API though, they need their own test cases. é)ÚBytesIO)Úminidom)Ú FileWrapperc@s(eZdZdZdd„Zdd„Zdd„ZdS) ÚIOPumpzŠUtility to pump data between clients and servers for protocol testing.
