NAME

Lustre::LFS::Dir - IO::Dir like module with lustre support

SYNOPSIS

use strict;
use Lustre::LFS::Dir;

my $fh = Lustre::LFS::Dir;
$d = Lustre::LFS::Dir->new(".");
my $stripes = $d->get_stripe;
$d->delete_stripe; # delete default striping
$d->set_stripe(Count=>3);

DESCRIPTION

"Lustre::LFS::Dir" inherits from "IO::Dir" (which inherits from "IO::Handle"), so a Lustre::LFS::Dir reference can do everything that an "IO::Dir" ref could do.

CONSTRUCTOR

See IO::Dir for details.

METHODS

Returns FALSE on error.
