Class UintMap

Implemented Interfaces:
Serializable

public class UintMap
extends java.lang.Object
implements Serializable

Map to associate non-negative integers to objects or integers. The map does not synchronize any of its operation, so either use it from a single thread or do own synchronization or perform all mutation operations on one thread before passing the map to others.
