NAME

Net::BitTorrent::Torrent - Class Representing a Single .torrent File

Description

Net::BitTorrent::Torrent objects are typically created by the Net::BitTorrent class.

Standalone Net::BitTorrent::Torrent objects can be made for informational use. See new ( ) and queue ( ).

Constructor

new ( { [ARGS] } )

Creates a Net::BitTorrent::Torrent object. This constructor is called by Net::BitTorrent::add_torrent( ).

new( ) accepts arguments as a hash, using key-value pairs:

BaseDir

The root directory used to store the files related to this torrent. This directory is created if not preexisting.

This is an optional parameter.

Default: ./ (Current working directory)

Client

The Net::BitTorrent object this torrent will eventually be served from.

This is an optional parameter.

No default. Without a defined parent client, his object is very limited in capability. Basic information and hash checking only. Orphan objects are obviously not queued automatically and must be added to a client manually.

Path

Filename of the .torrent file to load.

This is the only required parameter.

Status

Initial status of the torrent. This parameter is ORed with the loaded and queued (if applicable) values.

For example, you could set the torrent to automatically start after hashcheck with { [...] Status => 4, [...] }.

This is an optional parameter.

Default: 1 (started)

See also: status ( )

Note: This is alpha code and may not work correctly.

Methods

bitfield ( )

Returns a bitfield representing the pieces that have been successfully downloaded.

comment ( )

Returns the (optional) comment the original creator included in the .torrent metadata.

created_by ( )

Returns the (optional) "created by" string included in the .torrent metadata. This is usually a software version.

creation_date ( )

Returns the (optional) creation time of the torrent, in standard UNIX epoch format.

downloaded ( )

Returns the total amount downloaded from remote peers since the client started transferring data related to this .torrent.

See also: uploaded ( )

error ( )

Returns the most recent error that caused the software to set the error status. Torrents with active errors are automatically stopped and must be started.

See also: status ( ), start ( )

files ( )

Returns a list of Net::BitTorrent::Torrent::File objects representing all files contained in the related .torrent file.

hashcheck ( )

Verifies the integrity of all files associated with this torrent.

This is a blocking method; all processing will stop until this function returns.

See also: bitfield ( ), status ( )

infohash ( )

Returns the 20 byte SHA1 hash used to identify this torrent internally, with trackers, and with remote peers.

is_complete ( )

Returns a bool value based on download progress. Returns true when we have completed every file with a priority above 0. Otherwise, returns false.

See also: Net::BitTorrent::Torrent::File->priority()

name ( )

Returns the advisory name used when creating the related files on disk.

In a single file torrent, this is used as the filename by default. In a multiple file torrent, this is used as the containing directory for related files.

path ( )

Returns the filename of the torrent this object represents.

private ( )

Returns bool value dependent on whether the private flag is set in the .torrent metadata. Private torrents disallow information sharing via DHT and PEX.

queue ( CLIENT )

Adds a standalone (or orphan) torrent object to the particular CLIENT object's queue.

See also: remove_torrent ( )

raw_data ( )

Returns the bdecoded metadata. found in the .torrent file.

size ( )

Returns the total size of all files listed in the .torrent file.

status ( )

Returns the internal status of this Net::BitTorrent::Torrent object. States are bitwise AND values of...

Value	Type	Notes
1	Started	New peers are accepted and pieces are activly being transfered
2	Checking	Currently hashchecking (possibly in another thread)
4	Start after check	Unused in this version
8	Checked	Files of this torrent have been checked
16	Error	Activity is halted and may require user intervention (Unused in this version)
32	Paused	New peers are accepted but no piece date is transfered or asked for
64	Loaded	Torrent has been parsed without error
128	Queued	Has an associated Net::BitTorrent parent

For example, a status of 201 implies the torrent is queued (128), loaded (64), hash checked (8), and is currently active (1). This scheme is inspired by µTorrent.

When torrents have the a status that indicates an error, they must be restarted (if possible). The reason for the error may be returned by error ( ).

Note: States are alpha and may not work as advertised. Yet.

start ( )

Starts a paused or stopped torrent.

See also: status ( ), stop ( ), pause ( )

stop ( )

Stops an active or paused torrent. All related sockets (peers) are disconnected and all files are closed.

See also: status ( ), start ( ), pause ( )

pause ( )

Pauses an active torrent without closing related sockets.

See also: status ( ), stop ( ), start ( )

trackers

Returns a list of all Net::BitTorrent::Torrent::Tracker objects related to the torrent.

uploaded ( )

Returns the total amount uploaded to remote peers since the client started transferring data related to this .torrent.
