Class IrisQueryScheduler

All Implemented Interfaces:
IrisScheduler
Direct Known Subclasses:
IrisQuerySchedulerContinuous, IrisQuerySchedulerDaily, IrisQuerySchedulerDependent, IrisQuerySchedulerMonthly, IrisQuerySchedulerTemporary
public abstract class IrisQueryScheduler extends Object implements IrisScheduler
Base class for basic query scheduling object to contain the parameters used for scheduling. By itself it can not perform scheduling as it doesn't specify on what days a query should run, it simply specifies start/stop values. Since it can't handle scheduling by itself, the implementation of the IrisScheduler class is left to subclasses. Negative values for startTime and stopTime would be before 1970; they are used to indicate no start or stop time. This can happen if query scheduling is disabled, or we couldn't find a valid start time within the specified look-forward time.

  • Method Details

    • getRestartWhenRunningValues

    • getRestartWhenRunning

      @NotNull public IrisQueryScheduler.RestartWhenRunning getRestartWhenRunning()
      Get the actual value of restart-when-running. This does not define the behavior which can be overridden by subclasses. To determine whether the query should actually restart when running, use shouldRestartWhenRunning().
      Returns:
      the defined restart-when-running value

    • equals

      public boolean equals(Object object)
      Overrides:
      equals in class Object

      public LocalTime getStartTimeOfDay()
      Description copied from interface: IrisScheduler
      Get the schedulers start time as a general time of day. Note that this is not the next absolute start time given by IrisScheduler.getStartTimeInMillis()
      Specified by:
      getStartTimeOfDay in interface IrisScheduler
      Returns:
      a LocalTime representing the start time of the query

      Description copied from interface: IrisScheduler
      Get the time zone string that is used for all LocalTimes

    • getStartTimeInMillis

      public long getStartTimeInMillis()
      Description copied from interface: IrisScheduler
      Return the scheduler's next scheduled start time. This must be called after IrisScheduler.generateSchedulerTimes(Long, Map). A value of -1 means there is no start time.
      Specified by:
      getStartTimeInMillis in interface IrisScheduler
      Returns:
      the query's next start time in millis

    • getStopTimeInMillis

      public long getStopTimeInMillis()
      Description copied from interface: IrisScheduler
      Return the scheduler's next scheduled stop time. This must be called after IrisScheduler.generateSchedulerTimes(Long, Map). A value of -1 means there is no stop time.
      Specified by:
      getStopTimeInMillis in interface IrisScheduler
      Returns:
      the query's next start time in millis

    • hasStopTime

      public boolean hasStopTime()
      Description copied from interface: IrisScheduler
      Return true if the scheduling has a determinable stop time.
      Specified by:
      hasStopTime in interface IrisScheduler
      Returns:
      true if the scheduling has a determinable stop time, false otherwise

    • hasStartTime

      public boolean hasStartTime()
      Return true if the scheduling has a determinable start time.
