DESCRIPTION

MP3::Napster::Song provides object-oriented access to shared MP3 files that can be retrieved via the Napster network protocol.

OBJECT CONSTRUCTION

Song objects are normally not constructed de novo, but are returned by search() and browse() calls to MPEG::Napster objects.

OBJECT METHODS

Object methods provide access to various attributes of the sound file, and allow you to download the file to disk or pass its data to a pipe.

Accessors

The accessors provide read-only access to the Song object's attributes.

Accessor                Description
--------                -----------
$song->name             Title of the song, often including artist
$song->title            Same as above
$song->size             Physical size of file, in bytes
$song->bitrate          Bit rate of MP3 data, in kilobits/sec
$song->freq             Sampling frequency, in Hz
$song->length           Duration of song, in seconds
$song->owner            Owner of the song, as an MP3::Napster::User object
$song->path             Physical path of the song, at the remote end
$song->hash             MD5 hash of the first 300K of the song, for identification
$song->address          IP address of the client that holds the song
$song->link             The link speed of the owner, as a string (e.g. LINK_DSL)
$song->link_code        The link speed of the owner, as a numeric code (e.g. 3)
$song->server           The MP3::Napster object from which this song was retrieved

$transfer = $song->download( [$path | $fh] )

The download() method will initiate a download on the song. The method behaves like the MP3::Napster->download() method. If no argument is provided, the method will open up a file in the location specified by the MP3::Napster object's download_dir() method. Otherwise the song data will be written to the indicated path or filehandle.

If successful, the method will return a MP3::Napster::Transfer object, which can be used to monitor and control the download process.

String Overloading

If used in a string context, MPEG::Napster::Song objects will invoke the name() method. This allows the objects to be directly interpolated into strings, printed, and pattern matched.
