trait Timer extends AnyRef

Timers are used to schedule tasks in the future. They support both one-shot and recurring tasks.

Timers propagate Local state, including the Monitor, from when the task is scheduled to when it is run.

Note

Scheduling tasks with Timers should rarely be done directly; for example, when programming with Futures, prefer using Future.sleep.

  6. def doAt[A](time: Time)(f: ⇒ A): Future[A]

    Performs an operation at the specified time.

    Performs an operation at the specified time. Interrupting the Future will cancel the scheduled timer task, if not too late.

    Note

    Interrupts from returned Future will be translated into a task cancellation if and only if this Timer honors cancellations in schedule(Time)(f).

  7. def doLater[A](delay: Duration)(f: ⇒ A): Future[A]

    Performs an operation after the specified delay.

    Performs an operation after the specified delay. Interrupting the Future will cancel the scheduled timer task, if not too late.

    Note

    Interrupts from returned Future will be translated into a task cancellation if and only if this Timer honors cancellations in schedule(Time)(f).

  17. final def schedule(period: Duration)(f: ⇒ Unit): TimerTask

    Run f every elapsed period, starting period from now.

  18. final def schedule(when: Time, period: Duration)(f: ⇒ Unit): TimerTask

    Run f at time when; subsequently run f at every elapsed period.

    Run f at time when; subsequently run f at every elapsed period.

    Note

    If when is negative or undefined, it will be treated as Time.epoch.

    ,

    If period is negative or undefined, the timer task will be rescheduled immediately (i.e., period will be treated as Duration.Zero).

  19. final def schedule(when: Time)(f: ⇒ Unit): TimerTask

    Run f at time when.

    Run f at time when.

    Note

    If when is negative or undefined, it will be treated as Time.epoch.
