Package org.apache.pekko.actor.typed.javadsl

Class Adapter$

java.lang.Object

org.apache.pekko.actor.typed.javadsl.Adapter$

public class Adapter$
extends Object

Adapters between typed and classic actors and actor systems. The underlying ActorSystem is the classic pekko.actor.ActorSystem which runs Akka pekko.actor.typed.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 pekko.actor.ActorRef and pekko.actor.typed.ActorRef, and between classic pekko.actor.ActorSystem and pekko.actor.typed.ActorSystem.

spawn

public <T> ActorRef<T> spawn(ActorSystem sys,
 Behavior<T> behavior,
 String name,
 Props props)

props

public <T> Props props(Creator<Behavior<T>> behavior,
 Props deploy)

Wrap pekko.actor.typed.Behavior in a classic pekko.actor.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 pekko.actor.Props parameter. Cluster Sharding is an example of that.
