Kamaelia docs : Kamaelia.Util.SequentialTransformer

Sequential Transformer component

This component applies all the functions supplied to incoming messages. If the output from the final function is None, no message is sent.

Example Usage

To read in lines of text, convert to upper case, prepend "foo", and append "bar!" and then write to the console:

Pipeline(
    ConsoleReader(eol=""),
    SequentialTransformer( str,
                           str.upper,
                           lambda x : "foo" + x,
                           lambda x : x + "bar!",
                         ),
    ConsoleEchoer(),
).run()
