Pure Transformer component
This component applies a function specified at its creation to messages received (a filter). If the function returns None, no message is sent, otherwise the result of the function is sent to "outbox".
To read in lines of text, convert to upper case and then write to the console:
Pipeline( ConsoleReader(), PureTransformer(lambda x : x.upper()), ConsoleEchoer() ).run()
Got a problem with the documentation? Something unclear that could be clearer? Want to help improve it? Constructive criticism is very welcome - especially if you can suggest a better rewording!
Please leave you feedback here in reply to the documentation thread in the Kamaelia blog.
