Java implementation of TTL Cache

Cache

Java implementation of TTL Cache This project contain thread safe implementation of in-memory generic cahce using different eviction strategy.

Eviction Stratagey

1. TTL Cache TimeToLive cache works by evicting those data whose time to live has expired after regular interval of time.
2. LRU Cache LRU cache works by evicting the data using Least Recently Used algorithm.

Usage

Usage of the code can be seen in Cache class which is creating a Singleton wrapper cache class using TTL eviction strategy by creating TTLCache class instance.

public class Cache<K, V> {
        private static Cache mInstance = new Cache();

        private ICache<K,V> mCacheController;

        private Cache() {
            mCacheController = CacheFactory.<K, V>createCache(CacheType.TTLCache);
            mCacheController.init();
            mCacheController.setEvictionPeriod(5000);
            mCacheController.start();
        }
        ......
}

String key = "name";
String value = "Nikhil";
long timeToLive = 10000;
Cache<String, String> instance = Cache.getInstance();

Put

instance.put(key, value, timeToLive);

Get

assertEquals(value, instance.get(key));

Delete

instance.delete(key);
assertNotEquals(instance.get(key), value);

DeleteCache

instance.deleteCache();
assertNotEquals(instance.get(key), value);
