Class Cron

java.lang.Object
atessera.sensei.Cron
All Implemented Interfaces:
AutoCloseable
public class Cron extends Object implements AutoCloseable
Runs work() periodically on a dedicated daemon thread.

After each work() invocation the worker sleeps for the configured number of minutes. close() requests termination without interrupting an ongoing work() call; if the worker is currently sleeping, it is woken up so that shutdown does not wait for the whole interval.
