public SettingsPack connectionsLimit ( int value ) { sp . set_int ( settings_pack . int_types . connections_limit . swigValue ( ) , value ) ; return this ; }
|
Sets a global limit on the number of connections opened . The number of connections is set to a hard minimum of at least two per torrent so if you set a too low connections limit and open too many torrents the limit will not be met .

public SettingsPack maxPeerlistSize ( int value ) { sp . set_int ( settings_pack . int_types . max_peerlist_size . swigValue ( ) , value ) ; return this ; }
|
Sets the maximum number of peers in the list of known peers . These peers are not necessarily connected so this number should be much greater than the maximum number of connected peers . Peers are evicted from the cache when the list grows passed 90% of this limit and once the size hits the limit peers are no longer added to the list . If this limit is set to 0 there is no limit on how many peers we ll keep in the peer list .

|
public TorrentBuilder addNode ( Pair < String , Integer > value ) { if ( value != null ) { this . nodes . add ( value ) ; } return this ; }
|
This adds a DHT node to the torrent . This especially useful if you re creating a tracker less torrent . It can be used by clients to bootstrap their DHT node from . The node is a hostname and a port number where there is a DHT node running . You can have any number of DHT nodes in a torrent .

|
We expose type info in a context sensitive manner . For instance we only expose private features from within the containing class . We can determine the context class from the current compiling class . The compiling class is obtained from either 1 ) the actual CompiledGosuClass stack the Gosu Class TypeLoader manages or 2 ) from the class itself if it s not compiled yet . Note the latter case happens only on the UI side when a class is being edited .
