Class Store.LongObjectMap<V>

java.lang.Object

org.mapdb.Store.LongObjectMap<V>

Enclosing class:

Store

public static final class Store.LongObjectMap<V>
extends Object

Open Hash Map which uses primitive long as 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/remove operations are supported.

To iterate over collection one has to traverse set which contains keys, values are in separate field.
