public interface LifecycleAwareLatencyTracker
extends LatencyTracker

A LatencyTracker that tracks when it gets registered or unregistered with a cluster.

This interface exists only for backward-compatibility reasons: starting with the 3.0 branch of the driver, its methods are on the parent interface directly.

Method Summary

void	onRegister(Cluster cluster) Gets invoked when the tracker is registered with a cluster, or at cluster startup if the tracker was registered at initialization with Cluster.register(LatencyTracker).
void	onUnregister(Cluster cluster) Gets invoked when the tracker is unregistered from a cluster, or at cluster shutdown if the tracker was not unregistered.
