final class FileView
extends FilterFileView

An archive enabled file view. This class recognizes instances of the File class and returns custom icons and type descriptions if it's an archive file or an archive entry. Otherwise, the super class behaviour is used.

Note that this class accesses archive files lazily, i.e. it does not eagerly check the true status with File.isDirectory() or similar unless really necessary. This is to prevent dead locks between the Event Dispatch Thread and the Basic L&F File Loading Threads which are forked by JFileChooser.
