Interface DataRehashedEvent<K,V>

All Superinterfaces:

Event<K,V>

All Known Implementing Classes:

EventImpl

public interface DataRehashedEvent<K,V>
extends Event<K,V>

An event passed in to methods annotated with DataRehashed.

Note that the getConsistentHashAtStart() and getConsistentHashAtEnd() may return different value in the "pre" event notification and in the "post" event notification. For instance, the end CH in the "pre" notification may be a union of the start and end CHs in the "post" notification.

The result of the getNewTopologyId() method is not guaranteed to be the same for the "pre" and the "post" notification, either. However, the "post" value is guaranteed to be greater than or equal to the "pre" value.
