select

public Routee select(java.lang.Object message,
                     scala.collection.immutable.IndexedSeq<Routee> routees)

Description copied from interface: RoutingLogic

Pick the destination for a given message. Normally it picks one of the passed routees, but in the end it is up to the implementation to return whatever Routee to use for sending a specific message.

When implemented from Java it can be good to know that routees.apply(index) can be used to get an element from the IndexedSeq.

Specified by:

select in interface RoutingLogic

Parameters:

message - (undocumented)

routees - (undocumented)

Returns:

(undocumented)
