JavaTimer

class JavaTimer extends Timer

A Timer that is implemented via a java.util.Timer.

This timer has millisecond granularity.

If your code has a reasonably high throughput of task scheduling and can trade off some precision of when tasks run, Finagle has a higher throughput hashed-wheel implementation.

Note

Due to the implementation using a single Thread, be wary of scheduling tasks that take a long time to execute (e.g. blocking IO) as this blocks other tasks from running at their scheduled time.

  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.

    Timer
    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.

    log any Throwables caught by the internal TimerTask.

    log any Throwables caught by the internal TimerTask.

    By default we log to System.err but users may subclass and log elsewhere.

    This method MUST NOT throw or else your Timer will die.

  19. final def schedule(when: Time, period: Duration)(f: => Unit): TimerTask

    Note

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