Simple Cache is implementation of base cache logic with different storages. To use cache implement your Storage or use default MemoryStorage.
User user =...
String name = ...
//create manager
CacheManager cacheManager = new CacheManager();
//get user cache
Cache<String, User> userCache = cacheManager.getCache("UserCache");
//put into cache
userCache.put(name, user);
//get from cache
User user = userCache.get(name);User user =...
String name = ...
//create manager
CacheManager cacheManager = new CacheManager();
//get user cache
Cache<String, User> userCache = cacheManager.getCache("UserCache", new TreeStorage());
//put into cache
userCache.put(name, user);
//get from cache
User user = userCache.get(name);Cache interface describes simple operations. See the methods below.
public interface Cache<K, V> {
V get(K key);
void put(K key, V value);
String getName();
boolean isClosed();
void close();
}Storage interface describes basic methods to store key-value pair. See the methods below.
public interface Storage<K, V> {
void save(K key, V value);
V load(K key);
}Storage implementation can be such as memory storage, file storage, database storage, etc. Its implementation depends on your need. For example you can use different memory storages with more or less productive algorithms.
