AbstractScheduler

abstract class AbstractScheduler extends AbstractSchedulerBase

An Akka scheduler service. This one needs one special behavior: if Closeable, it MUST execute all outstanding tasks upon .close() in order to properly shutdown all dispatchers.

Furthermore, this timer service MUST throw IllegalStateException if it cannot schedule a task. Once scheduled, the task MUST be executed. If executed upon close(), the task may execute before its timeout.

Scheduler implementation are loaded reflectively at ActorSystem start-up with the following constructor arguments: 1) the system’s com.typesafe.config.Config (from system.settings.config) 2) a akka.event.LoggingAdapter 3) a java.util.concurrent.ThreadFactory

Abstract Value Members

  1. abstract def maxFrequency(): Double

    The maximum supported task frequency of this scheduler, i.e.

    The maximum supported task frequency of this scheduler, i.e. the inverse of the minimum time interval between executions of a recurring task, in Hz.

  2. abstract def schedule(initialDelay: FiniteDuration, interval: FiniteDuration, runnable: Runnable, executor: ExecutionContext): Cancellable

    Schedules a function to be run repeatedly with an initial delay and a frequency.

    Schedules a function to be run repeatedly with an initial delay and a frequency. E.g. if you would like the function to be run after 2 seconds and thereafter every 100ms you would set delay = Duration(2, TimeUnit.SECONDS) and interval = Duration(100, TimeUnit.MILLISECONDS)

  3. abstract def schedule(initialDelay: FiniteDuration, interval: FiniteDuration, runnable: Runnable)(implicit executor: ExecutionContext): Cancellable

    Schedules a Runnable to be run repeatedly with an initial delay and a frequency.

    Schedules a Runnable to be run repeatedly with an initial delay and a frequency. E.g. if you would like the function to be run after 2 seconds and thereafter every 100ms you would set delay = Duration(2, TimeUnit.SECONDS) and interval = Duration(100, TimeUnit.MILLISECONDS). If the execution of the runnable takes longer than the interval, the subsequent execution will start immediately after the prior one completes (there will be no overlap of executions of the runnable). In such cases, the actual execution interval will differ from the interval passed to this method.

    If the Runnable throws an exception the repeated scheduling is aborted, i.e. the function will not be invoked any more.

    Exceptions thrown

    IllegalArgumentException if the given delays exceed the maximum reach (calculated as: delay / tickNanos > Int.MaxValue). Java API

  4. abstract def scheduleOnce(delay: FiniteDuration, runnable: Runnable, executor: ExecutionContext): Cancellable

    Schedules a Runnable to be run once with a delay, i.e.

    Schedules a Runnable to be run once with a delay, i.e. a time period that has to pass before the runnable is executed.

  5. abstract def scheduleOnce(delay: FiniteDuration, runnable: Runnable)(implicit executor: ExecutionContext): Cancellable

    Schedules a Runnable to be run once with a delay, i.e.

    Schedules a Runnable to be run once with a delay, i.e. a time period that has to pass before the runnable is executed.
