Bio::Graphics::FeatureDir(3pm)

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.
