Interface CloseableLoadBalancingPolicy

All Superinterfaces:

Host.StateListener, LoadBalancingPolicy

All Known Implementing Classes:

DCAwareRoundRobinPolicy, HostFilterPolicy, LatencyAwarePolicy, RoundRobinPolicy, TokenAwarePolicy, WhiteListPolicy

public interface CloseableLoadBalancingPolicy
extends LoadBalancingPolicy

A load balancing policy that wants to be notified at cluster shutdown. The only reason that this is separate from LoadBalancingPolicy is to avoid breaking binary compatibility at the time this was introduced (2.0.7 / 2.1.3). It might be merged with the parent interface in a future major version.
