java - 非阻塞ServerSocketChannel

Question

SocketChannel socketChannel = serverSocketChannel.accept();

当非阻塞ServerSocketChannel返回SocketChannel时，调用socketChannel.configureBlocking(false)后，是否需要使用socketChannel.register(selector,SelectionKey.OP_CONNECT)注册SocketChannel ，新的ConnectionHandler)？

我假设一旦返回新的 SocketChannel，它就已经连接到远程端点，并且 socketChannel.isConnectionPending() 将返回 false 和 socketChannel.isConnected() 将返回 true。

public class ConnectionHandler
{
  public void handleConnect ( SelectionKey key )
  {
    SocketChannel socketChannel = SocketChannel.class.cast ( key.channel() );
    socketChannel.finishConnect ();

    socketChannel.register ( key.selector (), SelectionKey.OP_READ );
  }
}

Answer 1

When a Non-Blocking ServerSocketChannel returns a SocketChannel, after calling socketChannel.configureBlocking(false), is it required to then register the SocketChannel using socketChannel.register(selector,SelectionKey.OP_CONNECT,new ConnectionHandler)?

没有。已经连接了。 OP_CONNECT 适用于客户端。

I would assume that once the new SocketChannel has been returned that it is already connected to the remote endpoint and socketChannel.isConnectionPending() will return false and socketChannel.isConnected() will return true.

正确。
