在 Twig 中的私有 object 中访问数组中的值

Question

I want to get hold of the value of DashboardCalc, which lies in the following array:

array(1) {
  [0]=>
  object(MatrixSubHeadline)#27226 (4) {
    ["schemaHeadline":"MatrixSubHeadline":private]=>

        ["text":"MatrixQuestion":private]=>
        string(41) "Har du andre kommentarer til din trivsel?"
        ["index":"MatrixQuestion":private]=>
        int(0)
      }
    }
    ["questionMap":"MatrixSubHeadline":private]=>
    array(1) {
      [15612]=>
      array(1) {
        [0]=>
        int(0)
      }
    }
    ["useComments":"MatrixSubHeadline":private]=>
    bool(true)
  }
}

Please note: the array contains a few objects, which are private. I am not sure whether private objects can be accessed or not, or if the "private" is about the name, or the content. The data is inherited from a database.

You can access object value by using loop iteration like this: 
I am selecting here SchemaContentID, SchemaID and IndexNo.

{% for arrayObj in Objs %}
    <ul>
        <li>{{ Objs.SchemaContentID}}</li>
        <li>{{ Objs.SchemaID}}</li>
        <li>{{ Objs.IndexNo}}</li>
    </ul>
{% endfor %}
