3. 11.x core/modules/views/src/Entity/Render/EntityFieldRenderer.php \Drupal\views\Entity\Render\EntityFieldRenderer::buildFields()

Builds the render arrays for all fields of all result rows.

The output is built using EntityViewDisplay objects to leverage multiple-entity building and ensure a common code path with regular entity view.

• Each relationship is handled by a separate EntityFieldRenderer instance, since it operates on its own set of entities. This also ensures different entity types are handled separately, as they imply different relationships.
• Within each relationship, the fields to render are arranged in unique sets containing each field at most once (an EntityViewDisplay can only process a field once with given display options, but a View can contain the same field several times with different display options).
• For each set of fields, entities are processed by bundle, so that formatters can operate on the proper field definition for the bundle.

Parameters

\Drupal\views\ResultRow[] $values: An array of all ResultRow objects returned from the query.

Return value

array A renderable array for the fields handled by this renderer.
