```
public class CachedContentCleaner
extends Thread
implements FileHandler, org.springframework.context.ApplicationEventPublisherAware
```
Cleans up redundant cache files from the cached content file store. Once references to cache files are no longer in the in-memory cache, the binary content files can be removed.
