NAME
CDDB::File - Parse a CDDB/freedb data file

SYNOPSIS
  my $disc = CDDB::File->new("rock/f4109511");

  print $disc->id, $disc->all_ids;
  print $disc->artist, $disc->title;
  print $disc->year, $disc->genre, $disc->extd;
  print $disc->length, $disc->track_count;

  print $disc->revision, $disc->submitted_via, $disc->processed_by;

  foreach my $track ($disc->tracks) {
    print $track->number, $track->title, $track->artist;
    print $track->length, $track->extd;
  }

DESCRIPTION
This module provides an interface for extracting data from CDDB-format data files, as used by freedb.

It does not read data from your CD, or submit information to freedb.

METHODS

  new
  my $disc = CDDB::File->new("rock/f4109511");

This will create a new object representing the data in the file name specified.

  id / all_ids
  my $discid = $disc->id;
  my @discid = $disc->all_ids;

Due to how freedb works, one CD may have several IDs associated with it. 'id' will return the first of these (not necessarily related to the filename from which this was read), whilst 'all_ids' will return all of them.

  title / artist
The title and artist of this CD. For eponymous CDs these will be identical, even if the data file leaves the artist field blank.

  year
The (4-digit) year of release.

  genre
The genre of this CD. This is the genre as stored in the data file itself, which is not related to the 11 main freedb genres.

  extd
The "extended data" for the CD. This is used for storing miscellaneous information which has no better storage place, and can be of any length.

  length
The run time of the CD in seconds.

  track_count
The number of tracks on the CD.

  revision
Each time information regarding the CD is updated this revision number is incremented. This returns the revision number of this version.

  processed_by / submitted_via
The software which submitted this information to freedb and which processed it at the other end.

  tracks
  foreach my $track ($disc->tracks) {
    print $track->number, $track->title, $track->artist;
    print $track->length, $track->extd;
  }

Returns a list of Track objects, each of which knows its number (numering from 1), title, length (in seconds), offset, and may also have extended track data.

Tracks may also contain an 'artist' field. If this is not set the artist method will return the artist of the CD.
