Examples of java.nio.channels.spi.SelectorProvider

java.nio.channels.spi.SelectorProvider
Provider for nio selector and selectable channel.
The provider can be got by system property or the configuration file in a jar file, if not, the system default provider will return. The main function of this class is to return the instance of implementation class of DatagramChannel, Pipe, Selector , ServerSocketChannel, and SocketChannel. All the methods of this class are multi-thread safe.

    public static SocketChannel attach(int fd) throws Exception {
        Class<?> cls = UnsafeTcp.class.getClassLoader().loadClass("sun.nio.ch.SocketChannelImpl");


        Constructor<?> ctor = cls.getDeclaredConstructor(SelectorProvider.class, FileDescriptor.class, InetSocketAddress.class);


        SelectorProvider provider = SelectorProvider.provider();
        FileDescriptor fileDesc = UnsafeFs.createFileDescriptor( fd );


        ctor.setAccessible(true);
        SocketChannel socketChannel = (SocketChannel) ctor.newInstance(provider, fileDesc, null);
