I'm still interested in this. I can see the idea of multiple roots
being useful in an SMB file system, or local (Windows) file systems. Of
course, for others there would only be a single "root" (namely "/").
I'm writing a custom provider which could be pointing to either Linux or
Windows. Would it make sense to have a "getRoots" method in
FileProvider?
public FileName[] getRoots();
or possibly:
public FileObject[] getRoots();
which by default just returns a single entry with a path of "/"... Then
the default (local) file system provider would just return the results
of File.listRoots();
Then, Mark's idea of using an enum to get other user-relative
directories could also be (sort of) accommodated with a "getUserRoot()"
which returns the equivalent of "~" on *nix or OSX, and %USERPROFILE% on
Windows (Java "user.home") property.
The reason I think this is necessary is that, in order to do browsing of
all the files in a system, you need to be able to get to all the
relevant top-level locations. And for Samba (for a non-obvious
example), there typically will be multiple shared folders on a system
that you might want to pick from.
I can probably provide a patch by next week. Should I write up a JIRA?

Gary,
I'm not aware of the tilde being used for any other purpose in any other
file system. If a user had specified a directory like "~/mu~noz" as a
home directory it should resolve to the appropriate directory i.e.
"<User
Home>/mu~noz".
As for it being optional on a per file system basis, I suppose that's
possible. Is there a way of storing/registering file system
configurations (ala Spring Context)?
I hadn't really thought about it's use for other file systems. Merely
for use with the local file system. How would you use this in a
distributed file system? What would happen if the remote file system
did not have a home directory (or equivalent) for the current user?
Mark
Cheers,
Mark
