Package org.klomp.snark

Class TrackerClient

java.lang.Object
org.klomp.snark.TrackerClient
All Implemented Interfaces:
Runnable
public class TrackerClient
extends Object
implements Runnable
Informs metainfo tracker of events and gets new peers for peer coordinator. start() creates a thread and starts it. At the end of each run, a TimedEvent is queued on the SimpleTimer2 queue. The TimedEvent creates a new thread and starts it, so it does not clog SimpleTimer2. The thread runs one pass through the trackers, the PEX, and the DHT, then queues a new TimedEvent and exits. Thus there are only threads that are actively announcing, not one thread per torrent forever. start() may be called again after halt().
