Abstract Value Members

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

    Create new actor as child of this context with the given name, which must not be null, empty or start with “$”.

    Create new actor as child of this context with the given name, which must not be null, empty or start with “$”. If the given name is already in use, an InvalidActorNameException is thrown.

    See akka.actor.Props for details on how to obtain a Props object.

    Exceptions thrown
    akka.ConfigurationException

    if deployment, dispatcher or mailbox configuration is wrong

    akka.actor.InvalidActorNameException

    if the given name is invalid or already in use

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

    Create new actor as child of this context and give it an automatically generated name (currently similar to base64-encoded integer count, reversed and with “$” prepended, may change in the future).

    Stop the actor pointed to by the given akka.actor.ActorRef; this is an asynchronous operation, i.e. involves a message send. If this method is applied to the self reference from inside an Actor then that Actor is guaranteed to not process any further messages after this call; please note that the processing of the current message will continue, this method does not immediately terminate this actor.

Deprecated Value Members

  1. def actorFor(path: Iterable[String]): ActorRef

    Java API: Look-up an actor by applying the given path elements, starting from the current context, where ".." signifies the parent of an actor.

    Example:

    Look-up an actor by path; if it does not exist, returns a reference to the dead-letter mailbox of the akka.actor.ActorSystem. If the path point to an actor which is not local, no attempt is made during this call to verify that the actor it represents does exist or is alive; use watch(ref) to be notified of the target’s termination, which is also signaled if the queried path cannot be resolved.
