我学习Reactive/Mutiny。我试着用Mutiny读取文件的行。用命令式的方式来做，很简单：

public List<String> load(final InputStream inData) throws IOException {
    final List<String> content = new ArrayList<>();
    final BufferedReader bReader = new BufferedReader(new InputStreamReader(inData, ENCODING));
    String text;
    while ((text = bReader.readLine()) != null) {
        content.add(text);
    }
    return content;
}

我找不到任何React式的例子。看起来像：

final BufferedReader bReader = new BufferedReader(new InputStreamReader(inData, ENCODING));
Multi<String> multi = Multi.createFrom(bReader::readline);

我完全不碍事了吗？
