setTimeSlicesSubject

public void setTimeSlicesSubject(rx.subjects.PublishSubject<Date> timeSlicesSubject)

Test hook to broadcast when the job scheduler has finished all work for a time slice. This includes not only executing jobs that are scheduled for a particular time slice but also post-job execution clean up.

register

public void register(String jobType,
                     rx.functions.Func1<JobDetails,rx.Completable> jobProducer)
