Constructor Detail

RequestHandler

public RequestHandler()

This constructor does not initialize inherited fields. The user must subsequently call setSocket. We need this constructor so the server can use newInstance.

RequestHandler

public RequestHandler(java.net.Socket s)

Initializes all fields using provided socket.

Parameters:

s - The socket provided by the server.

Method Detail

setSocket

public void setSocket(java.net.Socket s)

Initialize all fields using the socket provided.

Parameters:

s - The socket provided by the server.

response

protected java.lang.String response(java.lang.String msg)

Override this method in a subclass. The default implementation merely appends the client message to the string "echo: ".

Parameters:

msg - The client's message.

run

public void run()

Perpetually receives a message from the client, creates a response, then sends the response back to the client. If the message is "quit" then the handler shuts down.
