class LightArrayRevolverScheduler extends Scheduler with Closeable

This scheduler implementation is based on a revolving wheel of buckets, like Netty’s HashedWheelTimer, which it advances at a fixed tick rate and dispatches tasks it finds in the current bucket to their respective ExecutionContexts. The tasks are held in TaskHolders, which upon cancellation null out their reference to the actual task, leaving only this shell to be cleaned up when the wheel reaches that bucket next time. This enables the use of a simple linked list to chain the TaskHolders off the wheel.

Also noteworthy is that this scheduler does not obtain a current time stamp when scheduling single-shot tasks, instead it always rounds up the task delay to a full multiple of the TickDuration. This means that tasks are scheduled possibly one tick later than they could be (if checking that “now() + delay <= nextTick” were done).

  29. def schedule(initialDelay: FiniteDuration, delay: 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.
