What uses that?
"string" could be interpreted as "complete message". It might e.g. happen that a message arrives in three chunks. Each time a chunk is read, the dataReceived method is called. When it detects that the message is complete, it calls stringReceived with the content of the message. Beware that the third chunk might also contain a part of the next message. This should of course _not_ be forwarded to stringReceived, but buffered until the next message is complete. It helped me a lot to read the source code in basic.py, which can be found in the directory twisted/protocols, or online here: http://twistedmatrix.com/trac/browser/tags/releases/twisted-10.2.0/twisted/protocols/basic.py It has lots of documentation and is very readable IMHO.
