Class RepositoryWatcher

java.lang.Object

org.appng.core.controller.RepositoryWatcher

All Implemented Interfaces:

Runnable

public class RepositoryWatcher
extends Object
implements Runnable

A service that watches for modified/deleted files in a Site's www-directory (see SiteProperties.WWW_DIR) using a WatchService.

If caching for the site is active (see SiteProperties.CACHE_ENABLED), cache entries for the modified/deleted files are removed from the cache. Since there could be some forwarding rules defined in the site's urlrewrite.xml, it is also necessary to parse these rules and remove the 'aliases' from the cache.
