Class FastHashMap<K,​V>

  • Type Parameters:
    K -
    V -
    All Implemented Interfaces:
    java.lang.Iterable<FastHashMap.Entry<K,​V>>
    public class FastHashMap<K,​V>
extends java.lang.Object
implements java.lang.Iterable<FastHashMap.Entry<K,​V>>
    Fast hash map implementation which uses array storage along with quadratic probing to resolve collisions. The capacity is doubled when the load goes beyond 50% and is halved when the load drops below 20%.
