April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.

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()
