Abstract:
|
||
|
|
|
||
|
|
This class is a virtual template for a FAT directory. It will be
|
||
|
|
passed to functions who wish to query the directory entries from the
|
||
|
|
directory without knowledge of how or where the directory is stored.
|
||
|
|
|
||
|
|
The user of this class will not be able to read or write the
|
||
|
|
directory to disk.
