Examples of com.opensymphony.oscache.base.Cache

com.opensymphony.oscache.base.Cache
Provides an interface to the cache itself. Creating an instance of this class will create a cache that behaves according to its construction parameters. The public API provides methods to manage objects in the cache and configure any cache event listeners. @version $Revision: 437 $ @author Mike Cannon-Brookes @author Todd Gochenour @author Francois Beauregard @author Chris Miller
