def __init__(self, isClient=1): (source)

Undocumented

def callExpressionReceived(self, obj): (source)

Undocumented

def connectionMade(self): (source)

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 connectionReady(self): (source)
Surrogate for connectionMade Called after protocol negotiation.
def dataReceived(self, chunk): (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.

Parameters
chunkUndocumented
dataa 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.
def expressionReceived(self, lst): (source)
Called when an expression (list, string, or int) is received.
def gotItem(self, item): (source)

Undocumented

def sendEncoded(self, obj): (source)
Send the encoded representation of the given object:
Parameters
objAn object to encode and send.
Returns
None
Raises
BananaErrorIf the given object is not an instance of one of the types supported by Banana.
def setPrefixLimit(self, limit): (source)
Set the prefix limit for decoding done by this protocol instance.
