Opens an asynchronous socket channel.

Usage

From source file:Test.java

public static void main(String[] args) throws Exception {

    AsynchronousSocketChannel client = AsynchronousSocketChannel.open();
    InetSocketAddress address = new InetSocketAddress("localhost", 5000);

    Future<Void> future = client.connect(address);
    System.out.println("Client: Waiting for the connection to complete");
    future.get();//  w  ww  .j a  v  a 2s.  c o m

    String message = "";
    while (!message.equals("quit")) {
        System.out.print("Enter a message: ");
        Scanner scanner = new Scanner(System.in);
        message = scanner.nextLine();
        System.out.println("Client: Sending ...");
        ByteBuffer buffer = ByteBuffer.wrap(message.getBytes());
        System.out.println("Client: Message sent: " + new String(buffer.array()));
        client.write(buffer);
    }
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    AsynchronousSocketChannel channel = AsynchronousSocketChannel.open();
    SocketAddress serverAddr = new InetSocketAddress("localhost", 8989);
    Future<Void> result = channel.connect(serverAddr);
    result.get();/*from w w w . j  ava2  s  . co m*/
    System.out.println("Connected");
    Attachment attach = new Attachment();
    attach.channel = channel;
    attach.buffer = ByteBuffer.allocate(2048);
    attach.isRead = false;
    attach.mainThread = Thread.currentThread();

    Charset cs = Charset.forName("UTF-8");
    String msg = "Hello";
    byte[] data = msg.getBytes(cs);
    attach.buffer.put(data);
    attach.buffer.flip();

    ReadWriteHandler readWriteHandler = new ReadWriteHandler();
    channel.write(attach.buffer, attach, readWriteHandler);
    attach.mainThread.join();
}
