Interface Scheduler

All Superinterfaces:
Monitorable
All Known Implementing Classes:
RemoteScheduler, SimpleScheduler
public interface Scheduler
extends Monitorable
Scheduler manages scheduling of actors to threads. As kontraktor 3.0 simplyfies scheduling compared to 2.0, this class currently doesn't do a lot.
