Examples of org.jboss.cache.loader.CacheLoaderManager

org.jboss.cache.loader.CacheLoaderManager
Manages all cache loader functionality. This class is typically initialised with an XML DOM Element, represeting a cache loader configuration, or a {@link org.jboss.cache.config.CacheLoaderConfig} object.
Usage:
CacheLoaderManager manager = new CacheLoaderManager(); manager.setConfig(myXmlSnippet, myTreeCache); CacheLoader loader = manager.getCacheLoader();
The XML configuration passed in would typically look like:

org.jboss.cache.loader.FileCacheLoader true false false location=/tmp/file ]]> @author Manik Surtani (manik AT jboss DOT org) @author Galder Zamarreno
