Class org.jos.fs.util.CachedMedium 

java.lang.Object
    |
    +----org.jos.fs.util.CachedMedium
public class CachedMedium
extends Object
implements Medium, MediumListener
A cached medium. Can't be distinguished from the underlying medium, but handles most read/write queries much faster by holding temporary copies of medium data in memory.

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