o run()
Runnable's run() method.
o writeOne(int, ClientHandler)
Method to send one int to all the clients except client that generated the int.
o writeOneInt(int, ClientHandler)
Method to send one int to all the clients, used to send player ID to Clients.
o writeToAllExcept(int, int, ClientHandler)

 private java.util.Vector clientHandlers
A Vector of ClientHandlers

o ss 
 private java.net.ServerSocket ss
A ServerSocket

 private java.lang.Thread runner
A Thread

o currentPlayerCount 
 public int currentPlayerCount
This is a field to keep track of the current number of players playing Breakout!

Constructors

o BOServer 
 public BOServer()
Constructor takes no arguments; creates a new ServerSocket on port 4321 Creates and starts a new Thread on this Object. Catches IOException.

Methods

o run 
 public void run()
Runnable's run() method. Accepts a connection, creating a Socket to listen on. If a Socket has been created, a new ClientHandler will be created and connected to that Socket and this BOServer. That ClientHandler is then added to a vector of ClientHandlers. Also increases the currentPlayerCount field by 1 to keep track of number of opened Sockets/ Clients. Catches IOException.

o writeToAllExcept 
 public synchronized void writeToAllExcept(int x,
                                           int y,
                                           breakout.ClientHandler ch)
Method to send the center coordinates of balls, represented by ints. Sends information to all ClientHandlers except the ClientHandler passed in as an argument, meant to be the ClientHandler that sent the information. Uses ClientHandler's sendCoords(int x, int y) method.

Parameters:
x - the x coordinate of the ball
y - the y coordinate of the ball
ClientHandler - the ClientHandler that sent the x and y coordinates
See Also:
sendCoords
o writeOneInt 
 public synchronized void writeOneInt(int i,
                                      breakout.ClientHandler ch)
Method to send one int to all the clients, used to send player ID to Clients. Sends information to all ClientHandlers. Sent by the ClientHandler that Uses ClientHandler's send(int i) method.

Parameters:
i - any integer that should be sent to all ClientHandlers
ClientHandler - the ClientHandler that should send the data, generally the one that produced the number

send
o writeOne 
 public synchronized void writeOne(int i,
                                   breakout.ClientHandler ch)
Method to send one int to all the clients except client that generated the int. Not sent to ClientHandler passed in as a parameter, which is meant to be the ClientHandler whose client is sending the int. Uses ClientHandler's send(int i) method.

Parameters:
i - any integer that should be sent to other players
ClientHandler - the ClientHandler that sent the data and should be excluded from being sent this information again

o removeClientHandler 
 public void removeClientHandler(breakout.ClientHandler ch)
Method to remove the ClientHandler specified as a parameter from the vector of ClientHandlers.
