LightWeight Java Torrent
LWJTorrent (LightWeight Java Torrent) is both a BitTorrent library and a client.
- As a library, it contains classes to deal with torrent related tasks.
- As a client, it provides a lightweight, simple and silent implementation of the BitTorrent protocol, which can be used by other applications without any user interaction. This is currently not implemented at all
LWJTorrent includes packages that contains classes that helps with BitTorrent-related tasks. These packages are the core of LWJTorrent, but can be perfectly used outside this project with little effort.
This package is completely stand-alone, something that should not be shocking, as it once was a fully independent project called Darkhogg-Bencode. It is just what it looks, a full Bencode library, with no dependencies outside the JDK, which can be used completely on its own.
Consists entirely of classes that models BitTorrent-related data. The most
important class here is the
TorrentMetaInfo class, which models a meta info
file, or in more common terms, a
A package that deals with tracker announces. The
Tracker class is
specifically designed as an abstract class that can only be instantiated by
TorrentMetaInfo object. Depending on the object passed, different
implementations may be used.
TrackerRequests are built by the user and sent
Tracker, which then responds with a
Probably the most important package in the whole library. This package models the BitTorrent protocol used to exchange data between peers. The name of the package is chosen after the name Peer Wire Protocol seen in some places, as the name protocol would have been confusing, as the tracker and meta info files also define protocols. This package seems complicated at first, but is in fact really easy to use.
An implementation of the Distributed Hash Table system used by BitTorrent for trackerless torrents.
