how-to

just simply like:

public class MyHandler implements Handler {

    private static final Logger LOGGER = LoggerFactory.getLogger(MyHandler.class);
    private long readSize;

    /**
     * The logic to deal with the received data.
     *
     * It means that reactor will trigger this function once the data is received.
     * @throws IOException
     */
    public void handle(FrontendConnection connection) throws IOException {
        Buffer buff = connection.getReadBuffer();
        readSize = +readSize + buff.position();
        LOGGER.info(connection.getId() + " connection has receive " + readSize);

    }

}

Handler handler = new MyHandler();
ReactorPool reactorPool = new ReactorPool(Runtime.getRuntime().availableProcessors(), handler);
new Acceptor(reactorPool, acceptorName, host, port).start();

adding a connection event or a connection multi-event:

public class RegisterHandler implements ConnectionEventHandler {
    private static final Logger LOGGER = LoggerFactory
            .getLogger(RegisterHandler.class);

    private static int INTERESTED = ConnectionEvents.REGISTE;

    public void event(FrontendConnection connection) {
        if ((event & INTERESTED) != 0) {
            //do something here
        }
    }

}

Handler handler = new NetHandler();
ConnectionEventHandler connectionEventHandler = new RegisterHandler();
ReactorPool reactorPool = new ReactorPool(Runtime.getRuntime().availableProcessors(), handler);
Acceptor acceptor = new Acceptor(reactorPool, acceptorName, host, port);
acceptor.addConnectionEventHandler(connectionEventHandler);
acceptor.start();

public class ConnectionLogHandler implements ConnectionEventHandler {
    private static final Logger LOGGER = LoggerFactory
            .getLogger(ConnectionLogHandler.class);
    private static int INTERESTED = ConnectionEvents.ACCEPT
            | ConnectionEvents.CLOSE;

    public void event(Connection connection, int event) {
        if ((event & INTERESTED) != 0) {
            if ((event & ConnectionEvents.ACCEPT) != 0)
                LOGGER.info("accept connection,id is " + connection.getId());
            if ((event & ConnectionEvents.CLOSE) != 0)
                LOGGER.info("close connection,id is " + connection.getId());
        }
    }
}

implements the connection

public class XXXConnection extends Connection {

    private String name;

    public XXXConnection(SocketChannel channel, long id, Reactor reactor) {
        super(channel, id, reactor);
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

public class XXXConnectionFactory implements ConnectionFactory {

    public XXXConnection createConnection(SocketChannel channel, long id,
            Reactor reactor) {
        return new XXXConnection(channel, id, reactor);
    }

}

Acceptor acceptor = new Acceptor(reactorPool, acceptorName, host,port);
acceptor.setConnectionFactory(new xxxConnectionFactory());
