[Interest] Qt 5: Converting QJsonValue to QJsonArray

I am trying out the new QJsonValue in Qt 5 and find myself wondering:
Does converting a QJsonValue which is an array to a QJsonArray with
QJsonValue::toArray() makes a copy of the underlying data?
Say I load a JSON file which is an object that contains an array with
thousands of items using QJsonDocument:
auto myObj = QJsonDocument::fromJson(jsonData).object();
auto myArray = myObject["theArray"].toArray();
How efficient is the conversion? Does it make a deep copy of the data in
the original object to the new array?
