Class LRUCache<K,V>
java.lang.Object
io.undertow.server.handlers.cache.LRUCache<K,V>
A non-blocking cache where entries are indexed by a key.
To reduce contention, entry allocation and eviction execute in a sampling fashion (entry hits modulo N). Eviction follows an LRU approach (oldest sampled entries are removed first) when the cache is out of capacity.
This cache can also be configured to run in FIFO mode, rather than LRU.
