Class Housekeeper

java.lang.Object

com.izforge.izpack.util.Housekeeper

public class Housekeeper
extends Object

This class performs housekeeping and cleanup tasks.
It is VERY important to perform pre-shutdown cleanup operations through this class. Do NOT rely on operations like deleteOnExit() shutdown hooks or finalize()for cleanup. Because shutDown() uses System.exit() to terminate, these methods will not work at all or will not work reliably.
