Instance Method Details

#bind_port=(port) ⇒ Object

Sets a “starting” bind port. Everytime a torrent is started, the library tries to bind this port, then the next one and so on until it is successful.

    return port;
}

#copy(path) ⇒ Object

Opens a torrent file at ‘path’ just as in Transmission#open, but creates an internal copy of it. Later you can open this torrent with Transmission#open_saved by passing it Torrent#hash_string value.

#open(path) ⇒ Object

Opens and parses torrent file at ‘path’. If the file exists and is a valid torrent file, returns a Torrent instance and adds it to the list of torrents (but doesn’t start it).
