All Implemented Interfaces:

Serializable, Cloneable, Iterable<AuthTime>, Collection<AuthTime>, Deque<AuthTime>, List<AuthTime>, Queue<AuthTime>

public class ReplayCache
extends LinkedList<AuthTime>

This class provides an efficient caching mechanism to store the timestamp of client authenticators. The cache minimizes the memory usage by doing self-cleanup of expired items in the cache.
