  - ### Method Detail

    - #### setErrorHandler

          public void setErrorHandler(ErrorHandler errorHandler)

      Provide an `ErrorHandler` strategy.

    - #### schedule

          public ScheduledFuture schedule(Runnable task,
                                 Trigger trigger)

      Description copied from interface: `TaskScheduler`
      Schedule the given `Runnable`, invoking it whenever the trigger indicates a next execution time.

      Execution will end once the scheduler shuts down or the returned `ScheduledFuture` gets cancelled.

      Specified by:
        `schedule` in interface `TaskScheduler`
      Parameters:
        `task` - the Runnable to execute whenever the trigger fires
        `trigger` - an implementation of the `Trigger` interface, e.g. a `CronTrigger` object wrapping a cron expression
      Returns:
        a `ScheduledFuture` representing pending completion of the task, or `null` if the given Trigger object never fires (i.e. returns `null` from `Trigger.nextExecutionTime(org.springframework.scheduling.TriggerContext)`)
      See Also:
        `CronTrigger`

    - #### schedule

          public ScheduledFuture schedule(Runnable task,
                                 Date startTime)

      Description copied from interface: `TaskScheduler`
      Schedule the given `Runnable`, invoking it at the specified execution time.

      Execution will end once the scheduler shuts down or the returned `ScheduledFuture` gets cancelled.

      Specified by:
        `schedule` in interface `TaskScheduler`
      Parameters:
        `task` - the Runnable to execute whenever the trigger fires
        `startTime` - the desired execution time for the task (if this is in the past, the task will be executed immediately, i.e. as soon as possible)
      Returns:
        a `ScheduledFuture` representing pending completion of the task

    - #### scheduleAtFixedRate

          public ScheduledFuture scheduleAtFixedRate(Runnable task,
                                            Date startTime,
                                            long period)

      Description copied from interface: `TaskScheduler`
      Schedule the given `Runnable`, invoking it at the specified execution time and subsequently with the given period.

      Execution will end once the scheduler shuts down or the returned `ScheduledFuture` gets cancelled.

      Specified by:
        `scheduleAtFixedRate` in interface `TaskScheduler`
      Parameters:
        `task` - the Runnable to execute whenever the trigger fires
        `startTime` - the desired first execution time for the task (if this is in the past, the task will be executed immediately, i.e. as soon as possible)
        `period` - the interval between successive executions of the task (in milliseconds)
      Returns:
        a `ScheduledFuture` representing pending completion of the task

    - #### scheduleAtFixedRate

          public ScheduledFuture scheduleAtFixedRate(Runnable task,
                                            long period)

      Description copied from interface: `TaskScheduler`
      Schedule the given `Runnable`, starting as soon as possible and invoking it with the given period.

      Description copied from interface: `TaskScheduler`
      Schedule the given `Runnable`, invoking it at the specified execution time and subsequently with the given delay between the completion of one execution and the start of the next.

      Execution will end once the scheduler shuts down or the returned `ScheduledFuture` gets cancelled.

      Specified by:
        `scheduleWithFixedDelay` in interface `TaskScheduler`
      Parameters:
        `task` - the Runnable to execute whenever the trigger fires
