java.lang.Object akka.routing.ScatterGatherFirstCompletedGroup
public final class ScatterGatherFirstCompletedGroup
A router group that broadcasts the message to all routees, and replies with the first response.
The configuration parameter trumps the constructor arguments. This means that
if you provide paths
during instantiation they will be ignored if
the router is defined in the configuration file for the actor being used.
param: paths string representation of the actor paths of the routees, messages are
sent with ActorSelection
to these paths
param: within expecting at least one reply within this duration, otherwise
it will reply with AskTimeoutException
in a Status.Failure
param: routerDispatcher dispatcher to use for the router head actor, which handles router management messages
