  org.jboss.cache.loader.DelegatingCacheLoader
      org.jboss.cache.loader.LocalDelegatingCacheLoader

All Implemented Interfaces:

CacheLoader, org.jboss.system.Service

public class LocalDelegatingCacheLoader
extends DelegatingCacheLoader

DelegatingCacheLoader implementation which delegates to a local (in the same VM) TreeCache. Sample code:

 TreeCache firstLevel=new TreeCache();
 TreeCache secondLevel=new TreeCache();
 DelegatingCacheLoader l=new DelegatingCacheLoader(secondLevel);
 l.setCache(firstLevel);
 firstLevel.setCacheLoader(l);
 secondLevel.start();
 firstLevel.start();
