Class FileSystemCleaner

java.lang.Object
com.nt.udc.util.FileSystemCleaner
All Implemented Interfaces:
ActionListener, EventListener
public class FileSystemCleaner extends Object implements ActionListener
This class handles file system cleaning, and has the option to make it timer based. The main idea is to use this is a routine where a directory becomes "expired", and is no longer used. When a directory is no longer in use, add it to the cleaner, and the timer will eventually delete it. Also, one may explicitly call "clean()" to delete any directories that the clean currently knows about.
