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();

Method Detail

setConfig

public void setConfig(Properties props)

Description copied from interface: CacheLoader

Sets the configuration. Will be called before Service.create() and Service.start()

Specified by:

setConfig in interface CacheLoader

Specified by:

setCache

public void setCache(TreeCache cache)

Description copied from interface: CacheLoader

This method allows the CacheLoader to set the TreeCache, therefore allowing the CacheLoader to invoke methods of the TreeCache. It can also use the TreeCache to fetch configuration information. Alternatively, the CacheLoader could maintain its own configuration
This method will be called directly after the CacheLoader instance has been created
