public class FileCleaningTracker
extends java.lang.Object
This utility creates a background thread to handle file deletion. Each file to be deleted is registered with a handler object. When the handler object is garbage collected, the file is deleted.
In an environment with multiple class loaders (a servlet container, for
example), you should consider stopping the background thread if it is no
longer needed. This is done by invoking the method
exitWhenFinished, typically in
ServletContextListener.contextDestroyed(javax.servlet.ServletContextEvent) or similar.
