Class BaseProtocol

Known Subclasses:

Protocol

This is the abstract superclass of all protocols.

If you are going to write a new protocol for Twisted, start here.  The
docstrings of this class explain how you can get started.  Any protocol
implementation, either client or server, should be a subclass of me.

My API is quite simple.  Implement dataReceived(data) to handle both
event-based and synchronous input; output can be sent through the
'transport' attribute, which is to be an instance that implements
L{twisted.internet.interfaces.ITransport}.

Some subclasses exist already to help you write common types of protocols:
see the L{twisted.protocols.basic} module for a few of them.

Called when a connection is made.

This may be considered the initializer of the protocol, because
it is called when the connection is completed.  For clients,
this is called once the connection to the server has been
established; for servers, this is called after an accept() call
stops blocking and a socket has been received.  If you need to
send any greeting or initial message, do it here.

Make a connection to a transport and a server.

This sets the 'transport' attribute of this Protocol, and calls the
connectionMade() callback.
