public class FileList
extends java.util.ArrayList<java.io.File>

This class extends ArrayList to add a finalize() that calls delete on the files . This helps in getting rid of the finalize() in the classes such as DefaultAbstractBag, and they can be freed up without waiting for finalize to be called. Only if those classes have spilled to disk, there will be a (this) class that needs to be finalized. CAUTION: if you assign a new value for a variable of this type, the files (if any) in the old object it pointed to will be scheduled for deletion. To avoid that call .clear() before assigning a new value.
