  • Element Details

    • cron

      String[] cron
      Default:
      {}

    • daysOfMonth

      int[] daysOfMonth
      1-31: for monthlyOnDayAndHourAndMinute(int dayOfMonth, int hour, int minute)
      Returns:
      Default:
      {}

    • daysOfWeek

      int[] daysOfWeek
      1-7 for SUN-SAT: for atHourAndMinuteOnGivenDaysOfWeek(int hour, int minute, Integer[] daysOfWeek)
      Returns:
      Default:
      {}

    • hour

      int hour
      0-23: for dailyAtHourAndMinute(int hour, int minute)
      Returns:
      Default:
      -1

    • minute

      int minute
      0-59
      Returns:
      Default:
      -1

    • second

      int second
      0-59
      Returns:
      Default:
      -1

    • fixedRate

      long fixedRate
      The fixedRate runs the scheduled task at every n millisecond. It doesn't check for any previous executions of the task. This is useful when all executions of the task are independent. If we don't expect to exceed the size of the memory and the thread pool, fixedRate should be quite handy. Although, if the incoming tasks do not finish quickly, it's possible they end up with “Out of Memory exception”.
      Returns:
      Default:
      0L

    • fixedDelay

      long fixedDelay
      The fixedDelay makes sure that there is a delay of n millisecond between the finish time of an execution of a task and the start time of the next execution of the task. This property is specifically useful when you need to make sure that only one instance of the task runs all the time. For dependent jobs, it is quite helpful.
      Returns:
      Default:
      0L

    • initialDelay

      long initialDelay
      start job after n millisecond
      Returns:
      Default:
      0L
