Class HashIndex

java.lang.Object

org.nustaq.reallive.server.storage.HashIndex

All Implemented Interfaces:

StorageIndex

public class HashIndex
extends Object
implements StorageIndex

acts as a passive listener to maintain state Consider: null indexHashValues need not to be tracked as a separate bucket, => fallback to full scan then ?
