reactor

Ultra lightweight, efficient and scalable Java TCP server with simple API.

How to use

Starting TCP server:

        InetSocketAddress address = new InetSocketAddress(InetAddress.getLocalHost(), PORT);
        Reactor<String> reactor = Reactor.<String>builder()
                .address(address)
                .eventHandler(new EchoEventHandler())
                .protocolFactory(new StringProtocolFactory())
                .threads(10)
                .backlog(100)
                .build();
        reactor.run();

where:

• address - server's InetSocketAddress
• eventHandler - implementation of EventHandler interface, see an example below
• protocolFactory - factory of Protocol implementations, see an example in reactor-protocol-string module
• threads - number of threads that will handle connections, each connection is always run on the same thread, default = 8
• backlog - server socket's backlog, default = 100
• reactor.run() - blocks the calling thread, runs the main loop

Example eventHandler:

public class EchoEventHandler implements EventHandler<String> {

    private final static Logger logger = LogManager.getLogger(EchoEventHandler.class);

    @Override
    public void onOpen(Connection<String> connection) {
        logger.info("New connection: {}", connection);
    }

    @Override
    public void onMessage(Connection<String> connection, String message) {
        logger.info("New message {} from {}", message, connection);
        connection.send(message);
    }

    @Override
    public void onClose(ConnectionData data) {
        logger.error("Connection closed {}", data);
    }

}
