2. 6.x src/Entity/QuizResultAnswerEntityTrait.php \Drupal\quiz\Entity\QuizResultAnswerEntityTrait::viewsGetAnswers()

Get answers for a question in a result.

This static method assists in building views for the mass export of question answers.

It is not as easy as instantiating all the question responses and returning the answer. To do this in views scalably we have to gather the data carefully.

This base method provides a very poor way of gathering the data.
