@MBean(objectName="CacheStore",
       description="Component that handles storing of entries to a CacheStore from memory.")
public class CacheWriterInterceptor
extends JmxStatsCommandInterceptor

Writes modifications back to the store on the way out: stores modifications back through the CacheLoader, either after each method call (no TXs), or at TX commit. Only used for LOCAL and INVALIDATION caches.
