Examples of org.apache.stratum.jcs.JCS

org.apache.stratum.jcs.JCS
Simple class for using JCS. To use JCS in your application, you can use the static methods of this class to get access objects (instances of this class) for your cache regions. Ideally this class should be all you need to import to use JCS. One JCS should be created for each region you want to access. If you have several regions, then get instances for each. For best performance the getInstance call should be made in an initialization method. @author Aaron Smuts @author James Taylor @created February 13, 2002 @version $Id: JCS.java,v 1.8 2002/02/18 17:14:24 asmuts Exp $
