Abstract Value Members

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

    Permalink

    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.

    UnsupportedOperationException if invoked on an ActorSystem that uses a custom user guardian

    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).

  3. abstract def become(behavior: Receive, discardOld: Boolean): Unit

    Permalink

    Changes the Actor's behavior to become the new 'Receive' (PartialFunction[Any, Unit]) handler.

    Changes the Actor's behavior to become the new 'Receive' (PartialFunction[Any, Unit]) handler. This method acts upon the behavior stack as follows:

    • if discardOld = true it will replace the top element (i.e. the current behavior)
    • if discardOld = false it will keep the current behavior and push the given one atop

    The default of replacing the current behavior on the stack has been chosen to avoid memory leaks in case client code is written without consulting this documentation first (i.e. always pushing new behaviors and never issuing an unbecome())

    Returns all supervised children; this method returns a view (i.e. a lazy collection) onto the internal collection of children. Targeted lookups should be using child instead for performance reasons:

    val badLookup = context.children find (_.path.name == "kid")

    val goodLookup = context.child("kid")

    Defines the inactivity timeout after which the sending of a akka.actor.ReceiveTimeout message is triggered.

    Defines the inactivity timeout after which the sending of a akka.actor.ReceiveTimeout message is triggered. When specified, the receive function should be able to handle a akka.actor.ReceiveTimeout message. 1 millisecond is the minimum supported timeout.

    Please note that the receive timeout might fire and enqueue the ReceiveTimeout message right after another message was enqueued; hence it is not guaranteed that upon reception of the receive timeout there must have been an idle period beforehand as configured via this method.

    Once set, the receive timeout stays in effect (i.e. continues firing repeatedly after inactivity periods). Pass in Duration.Undefined to switch off this feature.

    Messages marked with NotInfluenceReceiveTimeout will not reset the timer. This can be useful when ReceiveTimeout should be fired by external inactivity but not influenced by internal activity, e.g. scheduled tick messages.

    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.
