      Parameters:
      state - an Object representing the state of the load-balancer.

    • getStateLock

      Lock getStateLock()
      Get a lock that can be used to synchronize access to the load-balancer state. The main usage is to avoid race conditions when the state is serialized by the persistence thread, while it is being updated, in particular via its feedback() method, in another thread.
      Returns:
      a Lock object.
