trait ActorContext[T] extends AnyRef

An Actor is given by the combination of a Behavior and a context in which this behavior is executed. As per the Actor Model an Actor can perform the following actions when processing a message:

In Akka the first capability is accessed by using the ! or tell method on an ActorRef, the second is provided by ActorContext#spawn and the third is implicit in the signature of Behavior in that the next behavior is always returned from the message processing logic.

An ActorContext in addition provides access to the Actor’s own identity (“self”), the ActorSystem it is part of, methods for querying the list of child Actors it created, access to DeathWatch and timed message scheduling.

Abstract Value Members

  1. abstract def actorOf(props: actor.Props, name: String): actor.ActorRef

    Permalink

    Create an untyped child Actor from the given akka.actor.Props and with the given name.

  2. abstract def actorOf(props: actor.Props): actor.ActorRef

    Permalink

    Create an untyped child Actor from the given akka.actor.Props under a randomly chosen name.

    Create an untyped child Actor from the given akka.actor.Props under a randomly chosen name. It is good practice to name Actors wherever practical.

  3. abstract def child(name: String): Option[ActorRef[Nothing]]

    Permalink

    The named child Actor if it is alive.

  4. abstract def children: Iterable[ActorRef[Nothing]]

    Permalink

    The list of child Actors created by this Actor during its lifetime that are still alive, in no particular order.

  5. implicit abstract def executionContext: ExecutionContextExecutor

    Permalink

    This Actor’s execution context.

    This Actor’s execution context. It can be used to run asynchronous tasks like scala.concurrent.Future combinators.

  6. abstract def props: Props[T]

    Permalink

    The Props from which this Actor was created.

  7. abstract def schedule[U](delay: FiniteDuration, target: ActorRef[U], msg: U): Cancellable

    Permalink

    Schedule the sending of the given message to the given target Actor after the given time period has elapsed.

    Schedule the sending of the given message to the given target Actor after the given time period has elapsed. The scheduled action can be cancelled by invoking akka.actor.Cancellable cancel on the returned handle.

  8. abstract def self: ActorRef[T]

    Permalink

    The identity of this Actor, bound to the lifecycle of this Actor instance.

    The identity of this Actor, bound to the lifecycle of this Actor instance. An Actor with the same name that lives before or after this instance will have a different ActorRef.

  9. abstract def setReceiveTimeout(d: Duration): Unit

    Permalink

    Schedule the sending of a ReceiveTimeout notification in case no other message is received during the given period of time.

    Schedule the sending of a ReceiveTimeout notification in case no other message is received during the given period of time. The timeout starts anew with each received message. Provide Duration.Undefined to switch off this mechanism.

  10. abstract def spawn[U](props: Props[U], name: String): ActorRef[U]

    Permalink

    Create a child Actor from the given Props and with the given name.

  11. abstract def spawnAdapter[U](f: (U) ⇒ T): ActorRef[U]

    Permalink

    Create a child actor that will wrap messages such that other Actor’s protocols can be ingested by this Actor.

    Create a child actor that will wrap messages such that other Actor’s protocols can be ingested by this Actor. You are strongly advised to cache these ActorRefs or to stop them when no longer needed.

  12. abstract def spawnAnonymous[U](props: Props[U]): ActorRef[U]

    Permalink

    Create a child Actor from the given Props under a randomly chosen name.

    Create a child Actor from the given Props under a randomly chosen name. It is good practice to name Actors wherever practical.

  13. abstract def stop(child: ActorRef[Nothing]): Boolean

    Permalink

    Force the child Actor under the given name to terminate after it finishes processing its current message.

    Force the child Actor under the given name to terminate after it finishes processing its current message. Nothing happens if the ActorRef does not refer to a current child actor.

    returns

    whether the passed-in ActorRef points to a current child Actor

  14. abstract def system: ActorSystem[Nothing]

    Permalink

    The ActorSystem to which this Actor belongs.

  15. abstract def unwatch(other: actor.ActorRef): actor.ActorRef

    Permalink

    Revoke the registration established by watch.

    Revoke the registration established by watch. A Terminated notification will not subsequently be received for the referenced Actor.

  16. abstract def unwatch[U](other: ActorRef[U]): ActorRef[U]

    Permalink

    Revoke the registration established by watch.

    Revoke the registration established by watch. A Terminated notification will not subsequently be received for the referenced Actor.

  17. abstract def watch(other: actor.ActorRef): actor.ActorRef

    Permalink

    Register for Terminated notification once the Actor identified by the given akka.actor.ActorRef terminates.

    Register for Terminated notification once the Actor identified by the given akka.actor.ActorRef terminates. This notification is also generated when the ActorSystem to which the referenced Actor belongs is declared as failed (e.g. in reaction to being unreachable).

    Permalink

    Register for Terminated notification once the Actor identified by the given ActorRef terminates.
