# libmetasrv

This is a small framework for setting up a tcp/ip

server/client communication that I wrote back in 2007.

It's pretty easy to use

SimpleTest.java:

        public class SimpleTest {

          public static void main(String[] argv) throws MetaSrvException {

                if (argv.length < 2) { // No address provided, act as server.

                    SimpleServer myServer = new SimpleServer();

                    myServer.start();

                } else { // Address and port provided as first argument in format "example.com:1234"

                    String[] addrPort = argv[1].split(":");

                    SimpleServer myClient = new SimpleServer();

                    myClient.clientMode(addrPort[0], Integer.parseInt(addrPort[1]));

                }

          }

          static class SimpleClient extends MetaClient {

            BufferedReader input;

            public SimpleClient(MetaServer ms, Socket sock) {

                super(ms, sock);

                input = new BufferedReader(new java.io.InputStreamReader(iStream));

            }

            @Override

            public void process() {

                try {

                    if (!mServer.clientMode) {

                        // I'm a server, I Broadcast incoming messages to all connected clients.

                        mServer.broadcast(input.readLine().getBytes());

                    } else {

                        // I'm a client, I print all incoming messages

                        System.out.println(input.readLine());

                    }

                } catch (IOException ex) {

                    Logger.getLogger(SimpleTest.class.getName()).log(Level.SEVERE, null, ex);

                }

            }

            @Override

            public boolean handshake() {

                try {

                  if (!mServer.clientMode) {

                      // This instance is the server

                      String greeting = input.readLine();

                      if (greeting.equalsIgnoreCase("hello")) {

                        return true;

                      } else {

                        return false;

                      }

                  } else {

                    // This is instance the client

                    oStream.write("hello\n".getBytes());

                    return true;

                  }

                } catch (IOException ex) {

                    Logger.getLogger(SimpleTest.class.getName()).log(Level.SEVERE, null, ex);

                }

                return false;

            }

          }

          static class SimpleServer extends MetaServer {

            @Override

              protected void resetInstance() {

            }

            @Override

            public MetaClient newClient(Socket sock) {

                return new SimpleClient(this, sock);

            }

          }

        }
