Class Store.LongLongMap

java.lang.Object

org.mapdb.Store.LongLongMap

Enclosing class:

Store

public static final class Store.LongLongMap
extends Object

Open Hash Map which uses primitive long as values and keys.

This is very stripped down version from Koloboke Collection Library. I removed modCount, free value (defaults to zero) and most of the methods. Only put/get operations are supported.

To iterate over collection one has to traverse table which contains key-value pairs and skip zero pairs.

originaly part of Koloboke library, Roman Leventov, Higher Frequency Trading, heavily modified for MapDB
