Returns:

(undocumented)

getChild

public abstract InternalActorRef getChild(scala.collection.Iterator<java.lang.String> name)

Obtain ActorRef by possibly traversing the actor tree or looking it up at some provider-specific location. This method shall return the end result, i.e. not only the next step in the look-up; this will typically involve recursive invocation. A path element of ".." signifies the parent, a trailing "" element must be disregarded. If the requested path does not exist, return Nobody.

Parameters:

Returns:

(undocumented)

isLocal

public abstract boolean isLocal()

Scope: if this ref points to an actor which resides within the same JVM, i.e. whose mailbox is directly reachable etc.

Returns:

(undocumented)

isTerminated

public abstract boolean isTerminated()

Returns &ldquo;true&rdquo; if the actor is locally known to be terminated, &ldquo;false&rdquo; if alive or uncertain.
