sealed trait Accumulator[-E, +A] extends AnyRef

An accumulator of elements into a future of a result.

This is essentially a lightweight wrapper around a Sink that gets materialised to a Future, but provides convenient methods for working directly with that future as well as transforming the input.

Abstract Value Members

  1. abstract def asJava: libs.streams.Accumulator[E, A]

    Convert this accumulator to a Java Accumulator.

    Convert this accumulator to a Java Accumulator.

    returns

    The Java accumulator.

  2. abstract def map[B](f: (A) ⇒ B)(implicit executor: ExecutionContext): Accumulator[E, B]

    Map the result of this accumulator to something else.

  3. abstract def mapFuture[B](f: (A) ⇒ Future[B])(implicit executor: ExecutionContext): Accumulator[E, B]

    Map the result of this accumulator to a future of something else.

  4. abstract def recover[B >: A](pf: PartialFunction[Throwable, B])(implicit executor: ExecutionContext): Accumulator[E, B]

    Recover from errors encountered by this accumulator.

  5. abstract def recoverWith[B >: A](pf: PartialFunction[Throwable, Future[B]])(implicit executor: ExecutionContext): Accumulator[E, B]

    Recover from errors encountered by this accumulator.

  6. abstract def run(elem: E)(implicit materializer: Materializer): Future[A]

    Run this accumulator by feeding a single element into it.

  7. abstract def run()(implicit materializer: Materializer): Future[A]

    Run this accumulator by feeding nothing into it.

  8. abstract def run(source: Source[E, _])(implicit materializer: Materializer): Future[A]

    Run this accumulator by feeding in the given source.

  9. abstract def through[F](flow: Flow[F, E, _]): Accumulator[F, A]

    Return a new accumulator that first feeds the input through the given flow before it goes through this accumulator.

  10. abstract def toSink: Sink[E, Future[A]]

    Convert this accumulator to a Sink that gets materialised to a Future.

  20. def ~>:(source: Source[E, _])(implicit materializer: Materializer): Future[A]

    Right associative operator alias for run.

    Right associative operator alias for run.

    This can be used for a more fluent DSL that matches the flow of the data, for example:

    val intAccumulator: Accumulator[Int, Int] = ...
val source = Source(1 to 3)
val intFuture = source ~>: intAccumulator
  21. def ~>:[F](flow: Flow[F, E, _]): Accumulator[F, A]

    Right associative operator alias for through.

    Right associative operator alias for through.

    This can be used for a more fluent DSL that matches the flow of the data, for example:

    val intAccumulator: Accumulator[Int, Unit] = ...
val toInt = Flow[String].map(_.toInt)
val stringAccumulator = toInt ~>: intAccumulator
