akka.actor.typed.javadsl.Adapter

public class Adapter
extends java.lang.Object

Adapters between typed and classic actors and actor systems. The underlying ActorSystem is the classic ActorSystem which runs Akka Behavior on an emulation layer. In this system typed and classic actors can coexist.

These methods make it possible to create a child actor from classic parent actor, and the opposite classic child from typed parent. watch is also supported in both directions.

There are also converters (toTyped, toClassic) between classic ActorRef and ActorRef, and between classic ActorSystem and ActorSystem.

props

public static <T> Props props(Creator<Behavior<T>> behavior,

Wrap Behavior in a classic Props, i.e. when spawning a typed child actor from a classic parent actor. This is normally not needed because you can use the extension methods spawn and spawnAnonymous with a classic ActorContext, but it's needed when using typed actors with an existing library/tool that provides an API that takes a classic Props parameter. Cluster Sharding is an example of that.
