Class MiniMap<K,V>

java.lang.Object

one.microstream.collections.MiniMap<K,V>

Type Parameters:

K - the key type.

V - the value type.

All Implemented Interfaces:

Composition

public final class MiniMap<K,V>
extends Object
implements Composition

Straight forward minimal implementation of a strongly referencing identity hashing map.

This implementation is preferable to full scale implementations like HashEnum or EqHashEnum in cases where only basic mapping functionality but best performance and low memory need is required, for example to associate handler instances to class instances.
