protected  ExpiringLRUCacheImpl(String id)
    
protected  ExpiringLRUCacheImpl(String id, int maxsize, long timeout)

Constructor Detail
ExpiringLRUCacheImpl
protected ExpiringLRUCacheImpl(String id)(Code)



ExpiringLRUCacheImpl
protected ExpiringLRUCacheImpl(String id, int maxsize, long timeout)(Code)




Method Detail
get
public Object get(String key)(Code)
Retrieve an entry from the cache. This LRU cache supports timeouts, so if the cached object has expired then we return null, just as if the entry wasn't found.



put
public synchronized void put(String key, Object value)(Code)
Store an entry in the cache. We wrap the cached object in our ExpiringCacheEntry object so that we can track when the entry has expired.
