## Class ScheduledTimerTask

- java.lang.Object
- - org.springframework.scheduling.timer.ScheduledTimerTask

- Deprecated.
  as of Spring 3.0, in favor of the `scheduling.concurrent` package which is based on Java 5's `java.util.concurrent.ExecutorService`

      @Deprecated
      public class ScheduledTimerTask
      extends Object

  JavaBean that describes a scheduled `TimerTask`, consisting of the `TimerTask` itself or a `Runnable` to create a `TimerTask` for and a delay plus period. The period needs to be specified; there is no point in a default for it.

  The JDK's `Timer` facility does not offer sophisticated scheduling options such as cron expressions. Consider using Quartz for such advanced needs.

  Note that the `Timer` mechanism uses a `TimerTask` instance that is shared between repeated executions, in contrast to Quartz which creates a new Job instance for each execution.

  - ### Method Detail

    - #### setRunnable

          public void setRunnable(Runnable timerTask)

      Deprecated.
      Set the Runnable to schedule as TimerTask.
      See Also:
        `DelegatingTimerTask`

    - #### setTimerTask

          public void setTimerTask(TimerTask timerTask)

      Deprecated.
      Set the TimerTask to schedule.

    - #### getTimerTask

          public TimerTask getTimerTask()

      Deprecated.
      Return the TimerTask to schedule.

    - #### setDelay

          public void setDelay(long delay)

      Deprecated.
      Set the delay before starting the task for the first time, in milliseconds. Default is 0, immediately starting the task after successful scheduling.

    - #### getDelay

          public long getDelay()

      Deprecated.
      Return the delay before starting the job for the first time.

    - #### setPeriod

          public void setPeriod(long period)

      Deprecated.
      Set the period between repeated task executions, in milliseconds.

      Default is -1, leading to one-time execution. In case of a positive value, the task will be executed repeatedly, with the given interval inbetween executions.

      Note that the semantics of the period value vary between fixed-rate and fixed-delay execution.

      Note: A period of 0 (for example as fixed delay) is not supported, simply because `java.util.Timer` itself does not support it. Hence a value of 0 will be treated as one-time execution; however, that value should never be specified explicitly in the first place!

      See Also:
        `setFixedRate(boolean)`, `isOneTimeTask()`, `Timer.schedule(TimerTask, long, long)`

    - #### getPeriod

          public long getPeriod()

      Deprecated.
      Return the period between repeated task executions.

    - #### isOneTimeTask

          public boolean isOneTimeTask()

      Deprecated.
      Is this task only ever going to execute once?
      Returns:
        `true` if this task is only ever going to execute once
      See Also:
        `getPeriod()`

    - #### setFixedRate

          public void setFixedRate(boolean fixedRate)

      Deprecated.
      Set whether to schedule as fixed-rate execution, rather than fixed-delay execution. Default is "false", that is, fixed delay.

      See Timer javadoc for details on those execution modes.

      See Also:
        `Timer.schedule(TimerTask, long, long)`, `Timer.scheduleAtFixedRate(TimerTask, long, long)`

    - #### isFixedRate

          public boolean isFixedRate()

      Deprecated.
      Return whether to schedule as fixed-rate execution.
