package adapter
Scala API: Adapters between typed and untyped actors and actor systems.
The underlying ActorSystem
is the untyped akka.actor.ActorSystem
which runs Akka Typed akka.actor.typed.Behavior on an emulation layer. In this
system typed and untyped actors can coexist.
Use these adapters with import akka.actor.typed.scaladsl.adapter._
.
Implicit extension methods are added to untyped and typed ActorSystem
,
ActorContext
. Such methods make it possible to create typed child actor
from untyped parent actor, and the opposite untyped child from typed parent.
watch
is also supported in both directions.
There is an implicit conversion from untyped akka.actor.ActorRef to typed akka.actor.typed.ActorRef.
There are also converters (toTyped
, toClassic
) from typed
akka.actor.typed.ActorRef to untyped akka.actor.ActorRef, and between untyped
akka.actor.ActorSystem and typed akka.actor.typed.ActorSystem.

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