The following methods are provided in this framework:
/**
* Get size of cache
*
* @return size of cache
*/
int getSize();
/**
* Put a value into cache with a specified key
*
* @param key key
* @param value value to be cached
*/
void put(String key, Object value);
/**
* Get value from cache
*
* @param key key of object to get
* @return value from cache
*/
Optional<Object> get(String key);
/**
* Remove a specific entry from cache
*
* @param key key
*/
void remove(String key);
/**
* Checks if a key exists in cache
*
* @param key key
*/
boolean check(String key);
/**
* Clear cache
*/
void clear();
/**
* Evict cache. Same as clear.
*/
void evict();
- PerpetualLilCache:
- This simply uses Java's HashMap to store values.
- LRULilCache
- This implementation is based on the Least Recently Used principle
- It uses the
PerpetualLilCache
implementation through the decorator design pattern.
- TransitoryLilCache
- This implementation is based for the cases when you need to set an expiry time for the entries in the cache.
This is a simple implementation of different techniques used in caching frameworks, mainly to understand how it all works.
