Field Detail

clientSocket

protected java.net.Socket clientSocket

does the talking through the socket

out

protected java.io.OutputStream out

used for writing to the port

in

protected java.io.InputStream in

used for reading from the port

myServer

protected PortServer myServer

This clienthandler's server. This is used to let the server handle the clients on the way out.

Constructor Detail

ClientHandler

public ClientHandler(java.net.Socket client,
                     PortServer ms)
              throws java.io.IOException

Constructor for the ClientHandler. Creates the socket and the streams for communication.

ClientHandler

public ClientHandler()

Method Detail

init

public void init(java.net.Socket client,
                 PortServer ms)
          throws java.io.IOException

java.io.IOException

run

public void run()

Calls processClient, doneWithNetworkAccess, then closes the streams and Socket. Then returns.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

processClient

public void processClient()

Override this procedure to actually do the network access. No functionality is provided here.

internalDoneWithNetworkAccess

protected void internalDoneWithNetworkAccess()

called before the public doneWithNetworkAccess. This class provides a way for intermediate descendents to do some processing after the connection is closed. We will leave "doneWithNetworkAcess" for clientHandlers which actually are used in an application and save this method for more abstract classes. Make sure you call super() if you override this method.

doneWithNetworkAccess

public void doneWithNetworkAccess()

Called before the class exits. Use this method to process what processClient accomplished.
