Class LockFreeDictionary<K,V>

java.lang.Object
  org.amino.ds.lockfree.LockFreeDictionary<K,V>

Type Parameters:

K - type of key in the dictionary

V - type of value in the dictionary

All Implemented Interfaces:

java.util.Map<K,V>

public class LockFreeDictionary<K,V>
extends java.lang.Object
implements java.util.Map<K,V>

This is a thread-safe and lock-free dictionary. This lock free concurrent dictionary implementation is based on the algorithm defined in the follwoing paper: Scalable and Lock-Free Concurrent Dictionaries By Hakan Sundell and Philippas Tsigas
