Ignasi Marimon-Clos 0e7bce7bae The automatic replacement produces Markdown that caused the paradox task in sbt to timeout or event fail. So

this commit removes some operators with outpu too complex:

- ignored operators:
          "ask.md",
          "alsoTo.md",
          "batchWeighted.md",
          "buffer.md",
          "actorRef.md",
          "collect.md",
          "collection.md",
          "combine.md",
          "completionTimeout.md",
          "concat.md",
          "from.md",
          "fromMaterializer.md",
          "map.md",
          "merge.md",
          "queue.md",
          "log.md", // too many overloads, breaks `paradox` task
          "throttle.md", // too many overloads, breaks `paradox` task
          "idleTimeout.md", // too many overloads, breaks `paradox` task
          "setup.md",
          "watch.md",
          "withBackoff.md",
          "zip.md",
          "zipWith.md",
          "actorRefWithBackpressure.md"

- Ignored class when FQCN contains: Implicits, FlowOpsMat, SubSource, FlowOps, SubFlow, WithContext, DelayStrategy

- some extra manual cleanup on the committed operators.

fromJavaStream

Stream the values from a Java 8 Stream, requesting the next value when there is demand.

@refSource operators

Signature

@apidocStreamConverters.fromJavaStream { scala="#fromJavaStreamT,S<:java.util.stream.BaseStream[T,S]:akka.stream.scaladsl.Source[T,akka.NotUsed]" java="#fromJavaStream(akka.japi.function.Creator)" }

Description

Stream the values from a Java 8 Stream, requesting the next value when there is demand. The iterator will be created anew for each materialization, which is the reason the @scala[method] @java[factory] takes a @scala[function] @java[Creator] rather than an Stream directly.

You can use Source.async to create asynchronous boundaries between synchronous java stream and the rest of flow.

Example

Scala: @@snip From.scala { #from-javaStream }
Java: @@snip From.java { #from-javaStream }

Reactive Streams semantics

@@@div { .callout }

emits the next value returned from the iterator

completes when the iterator reaches its end

@@@
