NAME

       Bio::Graphics::FeatureDir -- A directory of feature files and conf files

SYNOPSIS

        my $fd = Bio::Graphics::FeatureDir->new('/path/to/dir');
        $fd->add_file('tracks.conf');
        $fd->add_file('foo.gff3');
        $fd->add_file('foo.wig');
        $fd->add_fh(\*STDIN);

        my $option   = $fd->setting('EST' => 'bgcolor');
        my @features = $fd->get_features_by_name('M101');

DESCRIPTION

       This class implements most of the methods of Bio::Graphics::FeatureFile, but stores the
       data files and features in a directory indexed by the
       Bio::DB::SeqFeature::Store::berkeleydb adaptor. Therefore it is fast.

   Methods
       $fd = Bio::Graphics::FeatureDir->new('/path/to/dir');
       $fd = Bio::Graphics::FeatureDir->new(-dir => '/path/to/dir');
           Create a new FeatureDir, based in the indicated directory. In addition to the -dir
           directory argument, it takes any of the options that can be passed to
           Bio::Graphics::FeatureFile except for the -file and -text arguments;

       $db->_init_featuredb
           Internal method. Initializes the underlying feature database.

       $db->_init_conf
           Internal method -- initialize the configuration file(s)

       $created = $db->_maybe_create_dir($dir)
           Create $dir and its parents if it doesn't exist. Return true if the directory was
           created. Throws an exception on filesystem errors.

       $dir = $db->dir
           Returns the base directory.

       $conf = $db->conf
           Returns the underlying Bio::Graphics::FeatureFile object

       $db = $db->db
           Returns the underlying Bio::DB::SeqFeature::Store object

       $db->add_file($file)
           Add the file to the directory. Can add files of type .fa, .gff, .gff3, .conf and .ff.

       $db->add_fh(\*FILEHANDLE [,'name'])
           Add the contents of the indicated filehandle to repository.  Name is optional; if
           provided it will be used as the base for all files created.
