CxxMina: 山寨 Mina2.0 实现的 C++ 强大 NIO 网络开发框架

##C++ network application framework like Mina2.0

*chinese version: [简体中文](README.zh_cn.md)*

####Characteristics

• Cross platform: support Linux32/64, OSX64, Win64 platforms;
• High performance: with the advantages of C/C++ and Java concurrent Libraries tegother, bursting performance;
• Easy to develop: first, use the java development, and then use the CxxJDK for translation, So easy!
• Perfect copycat: Mina core got CxxMina also have, MINA core is no CxxMina also have!

####Example java:

private final static Logger logger = LoggerFactory.getLogger("testmina");
private static volatile boolean gRunning = true;

static class DemoIoHandler implements IoHandler {

	@Override
	public void sessionCreated(IoSession session) throws Exception {
		logger.trace("sessionCreated");
		session.getConfig().setIdleTime(IdleStatus.BOTH_IDLE, 1);
	}

	@Override
	public void sessionOpened(IoSession session) throws Exception {
		logger.trace("sessionOpened");
	}

	@Override
	public void sessionClosed(IoSession session) throws Exception {
		logger.trace("sessionClosed");
	}

	@Override
	public void sessionIdle(IoSession session, IdleStatus status)
			throws Exception {
		logger.trace("sessionIdle");
	}

	@Override
	public void exceptionCaught(IoSession session, Throwable cause)
			throws Exception {
		logger.trace("exceptionCaught");
		session.closeNow();
	}

	@Override
	public void messageReceived(IoSession session, Object message)
			throws Exception {
		
		// response.
		IoBuffer out = IoBuffer.allocate(100);
		out.buf().put("HTTP/1.1 200 OK\r\nContent-Length: 11\r\nContent-Type: text/html\r\n\r\nHello,world".getBytes());
		out.flip();
		session.write(out);
		
		// close
		session.closeOnFlush();
	}

	@Override
	public void messageSent(IoSession session, Object message)
			throws Exception {
		logger.trace("messageSent");
	}

	@Override
	public void inputClosed(IoSession session) throws Exception {
		logger.trace("inputClosed");
		session.closeNow();
	}
}

public static void main(String[] args) {
	try {

		nsa.getFilterChain().addLast("logger", lf);
		nsa.getFilterChain().addLast("logger", lf);
		ProfilerTimerFilter pf = new ProfilerTimerFilter();
		nsa.getFilterChain().addLast("profile", pf);
		DemoIoHandler dih = new DemoIoHandler();
		nsa.setHandler(dih);
		InetSocketAddress isa = new InetSocketAddress(8888); //listen port.
		nsa.setReuseAddress(true);
		nsa.bind(isa);
		
		while (gRunning) {
			// do something.
			Thread.sleep(1000);
		}

		nsa.dispose(true);
	} catch (Throwable e) {
		e.printStackTrace();
	}
