Examples of org.jnode.fs.FSFile

org.jnode.fs.FSFile
A FSFile is a representation of a single block of bytes on a file system. It is comparable to an inode in Unix. An FSFile does not have any knowledge of who is using this file. It is also possible that the system uses a single FSFile instance to create two inputstream's for two different principals. @author epr
