    • nextScheduledTimeAfter

      long nextScheduledTimeAfter(long startTime, long now)
      Returns the next scheduled time after the given time, according to this schedule. If the given schedule cannot resolve the next scheduled time, then -1 is returned. It really depends on the type of schedule to determine when -1 is returned. Some schedules (e.g. IntervalSchedule) will never return -1 as they can always compute the next scheduled time. Cron based schedules are good example of schedules that may return -1, for example, when the schedule only points to times that are all before the given time (in which case, there is no next scheduled time for the given time). Example: cron 0 0 0 * 1 ? 2013 (only points to days in January 2013) time 2015-01-01 12:00:00 (this time is in 2015)
