 org.jaffa.cache.CacheSourceMonitor
| CacheSourceMonitor | | public class CacheSourceMonitor (Code) | | This is a helper class to monitor file(s), which provide data to a cache. The cache will be cleared, whenever any of the source files are modified. Note that any open iterators on the cache will have unpredictable results, whenever the cache is flushed.
Create an instance of this class, providing the cache and the file(s) to be monitored. Then invoke the startMonitoring method. This will create a daemon Thread, which will monitor the files for any changes. Invoke the stopMonitoring method to stop the thread.
