Inherited from Protocol:

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via Protocol):

Method makeConnection Make a connection to a transport and a server.
def __init__(self, *a, protocolFactory=None, **kw): (source)
ParametersprotocolFactoryA callable which will be invoked with *a, **kw and should return an ITerminalProtocol implementor. This will be invoked when a connection to this ServerProtocol is established.
aAny positional arguments to pass to protocolFactory.
kwAny keyword arguments to pass to protocolFactory.
def connectionMade(self): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.internet.protocol.BaseProtocol.connectionMade

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.

def dataReceived(self, data): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.internet.protocol.Protocol.dataReceived

Called whenever data is received.

Use this method to translate to a higher-level message. Usually, some callback will be made upon the receipt of each complete protocol message.

Parametersdataa string of indeterminate length. Please keep in mind that you will probably need to buffer some data, as partial (or multiple) protocol messages may be received! I recommend that unit tests for protocols call through to this method with differing chunk sizes, down to one byte at a time.
