Constructor Index

o ClientHandler(Socket, BOServer)
The constructor takes a Socket and a BOServer as parameters.

Method Index

o read()
Reads one int from the Client.
o run()
Runnable's run() method.
o send(int)
Sends the specified int to the BOClient connected by the DataOutputStream.
o sendCoords(int, int)
Sends two ints, x and y coordinates, to the BOClient connected by the DataOutputStream.

Variables

o server 
 private breakout.BOServer server
A BOServer

o client 
 private java.net.Socket client
the Socket connected to the BOClient

o dis 
 private java.io.DataInputStream dis
A DataInputStream

o dos 
 private java.io.DataOutputStream dos
A DataOutputStream

o runner 
 private java.lang.Thread runner

Constructors

o ClientHandler 
 public ClientHandler(java.net.Socket s,
                      breakout.BOServer server)
The constructor takes a Socket and a BOServer as parameters. It creates new DataInputStreams and DataOutputStreams connected to the Socket passed in as an argument. Equates its field currentPlayerCount to the BOServer's currentPlayerCount. Also, creates a new Thread on this Object and starts the Thread running.

Parameters:
Socket - the Socket through which this ClientHandler is connected to a client
BOServer - the central server through which information is broadcast

Methods

o run 
 public void run()
Runnable's run() method. Continuously reads any x and y coordinates being sent by its BOClient, and writes those coordinates to everyone except its BOClient. Catches IOException.

See Also:
writeOneInt, writeToAllExcept, readInt
o send 
 public void send(int i)
Sends the specified int to the BOClient connected by the DataOutputStream. Flushes after every write.

Parameters:
int - i the int which should be sent
See Also:
writeInt, flush
o sendCoords 
 public void sendCoords(int x,
                        int y)
Sends two ints, x and y coordinates, to the BOClient connected by the DataOutputStream. Flushes after every write.

Parameters:
int - x the x coordinate to be sent
int - y the y coordinate to be sent
See Also:
writeInt, flush
o read 
 public int read()
Reads one int from the Client. Returns that int. Generally, either the x or the y coordinate of the ball.

Returns:
i the int read from the DataInputStream
See Also:
readInt
