Type Members

  1. trait DelayStrategy[T] extends AnyRef

    Allows to manage delay and can be stateful to compute delay for any sequence of elements, all elements go through nextDelay() updating state and returning delay for each element

  4. def apply[T](strategySupplier: () ⇒ DelayStrategy[_ >: T]): Flow[T, T, NotUsed]

    Flow for universal delay management, allows to manage delay through DelayStrategy.

    Flow for universal delay management, allows to manage delay through DelayStrategy. It determines delay for each ongoing element invoking DelayStrategy.nextDelay(elem: T): FiniteDuration. Implementing DelayStrategy with your own gives you flexible ability to manage delay value depending on coming elements. It is important notice that DelayStrategy can be stateful. There are also predefined strategies, see DelayStrategy companion object's methods.

    For example:

    //delay, infinitely increasing by `1 second` on every Failure
     new DelayStrategy[Try[AnyRef]]{
       var delay = Duration.Zero
       override def nextDelay(elem: Try[AnyRef]): FiniteDuration = {
         if(elem.isFailure){
           delay += (1 second)
         }
         delay
       }
     }
    strategySupplier

    creates new DelayStrategy object for each materialization
