Class LRUHashbelt<K,V>

java.lang.Object
  org.castor.cache.AbstractBaseCache<K,V>
      org.castor.cache.hashbelt.AbstractHashbelt<K,V>
          org.castor.cache.hashbelt.LRUHashbelt<K,V>

Type Parameters:

K - the type of keys maintained by this cache

V - the type of cached values

All Implemented Interfaces:

Map<K,V>, Cache<K,V>

public final class LRUHashbelt<K,V>
extends AbstractHashbelt<K,V>

A type of hashbelt that moves requested elements back into the first container when a get or add occurs.

Objects which are rarely used will work their way down the conveyor belt, and eventually be discarded, if they are not referenced.
