Class game.GameLinkFilter 

java.lang.Object
   |
   +----game.GameLinkFilter
public class GameLinkFilter
extends Object
implements GameLinkListener
When a Jags client is connected to a Jags server, it can open multiple games on this server. All those games will share the same GameLink object, so we need a way to sort network messages addressed to different games. This is done through the GameLinkFilter class.

Variable Index

o gameId
The id of the game this GameLinkFilter corresponds to.
o gameLink
The underlying GameLink object.
o listeners
Set of listeners of this GameLinkFilter object.

Constructor Index

o GameLinkFilter(Object, GameLink)
Creates a new GameLinkFilter [DESCRIBE ME]

Method Index

o addGameLinkListener(GameLinkListener, int)
Adds the specified listener to the sets of listeners of this GameLinkFilter object.
o deleteGameLinkListener(GameLinkListener, int)
Removes the specified listener from the sets of listeners of this GameLink object for the given group.
o frameReceived(Object, LinkFrame)
Messaged when a new data frame is received by the GameLink object and this frame belongs to the groups the GameLinkListener asked to listen to.
o notifyListeners(LinkFrame)
experimental.
o send(LinkFrame)
Sends the given frame over the network.
o sendBlindly(LinkFrame)
experimental.
