Method Details

dataReceived(self, data)

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:
data - a 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.
Overrides:
twisted.internet.protocol.Protocol.dataReceived (inherited documentation)
