Class org.jos.fs.util.ImageFileMedium 

java.lang.Object
    |
    +----org.jos.fs.util.ImageFileMedium
public class ImageFileMedium
extends Object
implements Medium
maintains an image file and offers access to it via the Medium interface

There are two possible uses of this class:

  1. when testing under a host OS, install a virtual disk to debug a JOS file system
  2. create a virtual disk inside another disk (a la DoubleSpace, Stacker etc., remember?)

This is a thread-safe class (as required by org.jos.fs.Medium).
