   private NioSocketConnector connector = new NioSocketConnector();

  ConnectFuture future1 = connector.connect(address);

AbstractIoConnector 中 
public final ConnectFuture connect(SocketAddress remoteAddress,
            SocketAddress localAddress, IoSessionInitializer sessionInitializer) 方法

到 AbstractPollingIoConnector

protected final ConnectFuture connect0(
            SocketAddress remoteAddress, SocketAddress localAddress,
            IoSessionInitializer sessionInitializer)

方法

 protected final ConnectFuture connect0(
            SocketAddress remoteAddress, SocketAddress localAddress,
            IoSessionInitializer sessionInitializer) {
        H handle = null;
