Test::MockFile::DirHandle - Provides a class object for L<Test::MockFile> to give out for opendir calls.

Version 0.021

=cut

=head1 SYNOPSIS

This is a helper class for L<Test::MockFile> its only purpose is to provide a object to recognize that a the passed handle is a mocked handle.
L<Test::MockFile> has to mock the other calls since there is no tie for B<opendir> handles.

    # This is what Test::MockFile does. You really shouldn't be doing it directly.
    use Test::MockFile::DirHandle;
    my $handle = Test::MockFile::DirHandle->new("/fake/path", [qw/. .. a bbb ccc dd/]);

=head1 EXPORT

No exports are provided by this module.

=head1 SUBROUTINES/METHODS

=head2 new

Args: ($class, $dir, $files_array_ref)

Returns a blessed object for Test::MockFile::DirHandle. There are no error conditions handled here.

B<NOTE:> the permanent directory contents are stored in a hash in Test::MockFile. However when opendir
is called, a copy is stored here. This is because through experimentation, we've determined that adding
files in a dir during a opendir/readdir does not affect the return of readdir.

See L<Test::MockFile>.

    my ( $class, $dir, $files_in_readdir ) = @_;

    return bless {
        files_in_readdir => $files_in_readdir,
        'dir'            => $dir,
        'tell'           => 0,
    }, $class;
