How to detect successful connection?

[birnbuazn]

Hi Pavlov,

I try to open a connection right before sending a message, but didn't find a way to get hold of a Future which will be completed, once the connection to a server has been established, so had to resort to busy waiting:

  void send(IsoMessage message) throws InterruptedException {
      reconnectIfNecessary();
      client.send(message);
  }  

 private void reconnectIfNecessary() throws InterruptedException {
    if (!client.isConnected()) {
      client.connect();
    }
    waitForConnection();
  }

  @SuppressWarnings("BusyWait")
  private void waitForConnection() throws InterruptedException {
    int retry = 0;
    while (!client.isConnected()) {
      checkState(retry < 10, "Client channel is not connected after %s ms", retry * 100);
      Thread.sleep(100);
      retry++;
    }
  }

There sure must be a better way of handling this?
