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.

Send out a message with the given queries.

ParametersqueriesThe queries to transmit (type: list of Query instances)
