Interface ClientCommandHandler

All Known Implementing Classes:

CommandHandler

public interface ClientCommandHandler

This interface defines the methods that should be implemented by any class that wants to handle character/string data from client.

Recommendations to be followed when implementing ClientCommandHandler

• Should have a default constructor.
• Should be thread safe.
• It should not store any data that may is associated with a particular client.
• If any client data is need to be saved from the client session, it should be saved to a ClientData class, which can be retrieved using handler.getClientData() method.

Ex:

package echoserver;

import java.net.*;
import java.io.*;
import org.quickserver.net.server.ClientCommandHandler;
import org.quickserver.net.server.ClientHandler;

public class EchoCommandHandler implements ClientCommandHandler {

        public void handleCommand(ClientHandler handler, String command)
                        throws SocketTimeoutException, IOException {
                if(command.toLowerCase().equals("quit")) {
                        handler.sendClientMsg("Bye ;-)");
                        handler.closeConnection();
                } else {
                        handler.sendClientMsg("Echo : " + command);
                }
        }
}
