An AccessExpireLRUCache combines LRU caching and time based expire caching. It cache entries for a fixed time period (per default 10 minutes) but also limits the size of the cache (per default: 1024). { public: AccessExpireLRUCache(long cacheSize = 1024, Timestamp::TimeDiff expire = 600000): AbstractCache<TKey, TValue, StrategyCollection<TKey, TValue> >(StrategyCollection<TKey, TValue>()) { this->_strategy.pushBack(new LRUStrategy<TKey, TValue>(cacheSize)); this->_strategy.pushBack(new AccessExpireStrategy<TKey, TValue>(expire)); }
