Cheap And Cheerful Clock
Outputs the message True repeatedly. The interval between messages is the parameter "interval" specified at the creation of the component.
This component is useful because it allows another component to sleep, not using any CPU time, but waking periodically (components are unpaused when they are sent a message).
Why is it "cheap and cheerful"?
...Because it uses a thread just for itself. All clocks could share a single thread if some services kung-fu was pulled. Opening lots of threads is a bad thing - they have much greater overhead than normal generator-based components. However, the one-thread-per-clock approach used here is many times shorter and simpler than one using services.
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.
