Examples of org.apache.excalibur.store.Store

org.apache.excalibur.store.Store
A Store is an object managing arbitrary data. It holds data stored under a given key persistently. So if you put something in a store you can be sure that the next time (even if the application restarted) your data is in the store (of course unless noone else did remove it). In some cases (like for example a cache) the data needs not to be persistent. Therefore with the two role TRANSIENT_STORE and PERSISTENT_STORE you get a store with exactly that behaviour. @author Avalon Development Team @version CVS $Id: Store.java,v 1.5 2004/02/28 11:47:34 cziegeler Exp $
