Interface Scheduler

All Known Implementing Classes:
DefaultScheduler

public interface Scheduler

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.


Method Summary
 Cancellable schedule(scala.concurrent.duration.FiniteDuration initialDelay, scala.concurrent.duration.FiniteDuration interval, ActorRef receiver, java.lang.Object message, scala.concurrent.ExecutionContext executor)
          Schedules a message to be sent repeatedly with an initial delay and frequency.
 Cancellable schedule(scala.concurrent.duration.FiniteDuration initialDelay, scala.concurrent.duration.FiniteDuration interval, scala.Function0<scala.runtime.BoxedUnit> f, scala.concurrent.ExecutionContext executor)
          Schedules a function to be run repeatedly with an initial delay and a frequency.
 Cancellable schedule(scala.concurrent.duration.FiniteDuration initialDelay, scala.concurrent.duration.FiniteDuration interval, java.lang.Runnable runnable, scala.concurrent.ExecutionContext executor)
          Schedules a function to be run repeatedly with an initial delay and a frequency.
 Cancellable scheduleOnce(scala.concurrent.duration.FiniteDuration delay, ActorRef receiver, java.lang.Object message, scala.concurrent.ExecutionContext executor)
          Schedules a message to be sent once with a delay, i.e. a time period that has to pass before the message is sent.
 Cancellable scheduleOnce(scala.concurrent.duration.FiniteDuration delay, scala.Function0<scala.runtime.BoxedUnit> f, scala.concurrent.ExecutionContext executor)
          Schedules a function to be run once with a delay, i.e. a time period that has to pass before the function is run.
 Cancellable scheduleOnce(scala.concurrent.duration.FiniteDuration delay, java.lang.Runnable runnable, scala.concurrent.ExecutionContext executor)
          Schedules a Runnable to be run once with a delay, i.e. a time period that has to pass before the runnable is executed.
 

Method Detail

schedule

Cancellable schedule(scala.concurrent.duration.FiniteDuration initialDelay,
                     scala.concurrent.duration.FiniteDuration interval,
                     ActorRef receiver,
                     java.lang.Object message,
                     scala.concurrent.ExecutionContext executor)
Schedules a message to be sent repeatedly with an initial delay and frequency. E.g. if you would like a message to be sent immediately and thereafter every 500ms you would set delay=Duration.Zero and interval=Duration(500, TimeUnit.MILLISECONDS)

                     scala.concurrent.ExecutionContext executor)
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)
