Very easy FIFO cache

There are plenty of times when you need a cache for Java objects in your code. A very easy to use and simple implementation of a cache is provided with Apache ORO, wisely called CacheFIFO (http://jakarta.apache.org/oro/api/org/apache/oro/util/CacheFIFO.html).
This is a very simple example of how I used it to cache user POJOs in an enterprise applications back-end:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | import org.apache.oro.util.CacheFIFO; public class UserHandler { private static CacheFIFO cache = new CacheFIFO(100); public static void addUser (String login, User u){ cache.addElement(login, u); } public static User getUser (String login){ return (User)cache.getElement(login); } } |
