The DSB provides a simple way to create recurrent tasks known has cronjobs by adding annotations on methods to call regularly. This comes from the fact that in a system, you generally have to periodically do things. The DSB ease this task creation from the developer point of view by introducing a simple Job annotation defined like

By putting this annotation on a method, it will be called periodically. The period is configured with the annotation parameters. For example:

The method iAmACronJob will be fired 20 seconds after the DSB startup, and will occurs every 20 seconds.

The parameter must not have any parameter and must be public. Return values are not handled.

To use it, just put the annotation, as many other annotation based stuff, the DSB will introspect the kernel components and will create the jobs for you.
