t.p.s.StatefulProtocol(protocol.Protocol) : class documentation

Part of twisted.protocols.stateful View Source View In Hierarchy

A Protocol that stores state for you.

state is a pair (function, num_bytes). When num_bytes bytes of data arrives from the network, function is called. It is expected to return the next state or None to keep same state. Initial state is returned by getInitialState (override it).
Method makeConnection Make a connection to a transport and a server.
Method getInitialState Undocumented
Method dataReceived Called whenever data is received.

Inherited from Protocol:

Method connectionLost Called when the connection is shut down.

Inherited from BaseProtocol (via Protocol):

Method connectionMade Called when a connection is made.
def makeConnection(self, transport): (source)

Make a connection to a transport and a server.

This sets the 'transport' attribute of this Protocol, and calls the connectionMade() callback.
def getInitialState(self): (source)
def dataReceived(self, data): (source)

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.
