Reading messages

Give a brief description of the usage of this connector. If you want to mention a class name, make sure to link to the API docs: ReferenceReadResult.

If any of the API classes are different between Scala and Java, link to both API docs: Reference Reference.

Show an example code snippet of how a source of this connector can be created.

Scala
val settings: SourceSettings = SourceSettings(ClientId)

val source: Source[ReferenceReadResult, Future[Done]] =
  Reference.source(settings)
Java
final SourceSettings settings = SourceSettings.create(clientId);

final Source<ReferenceReadResult, CompletionStage<Done>> source = Reference.source(settings);

Wrap language specific text with language specific directives, like @scala for Scala specific text@java for Java specific text.

Writing messages

Show an example code snippet of how a flow of this connector can be created.

Scala
val flow: Flow[ReferenceWriteMessage, ReferenceWriteResult, NotUsed] =
  Reference.flow()
Java
final Flow<ReferenceWriteMessage, ReferenceWriteResult, NotUsed> flow = Reference.flow();
