  3. 10 core/lib/Drupal/Core/Entity/EntityViewBuilder.php \Drupal\Core\Entity\EntityViewBuilder::buildMultiple()

Builds multiple entities' views; augments entity defaults.

This function is assigned as a #pre_render callback in ::viewMultiple().

By delaying the building of an entity until the #pre_render processing in \Drupal::service('renderer')->render(), the processing cost of assembling an entity's renderable array is saved on cache-hit requests.

Parameters

array $build_list: A renderable array containing build information and context for an entity view.

Return value

array The updated renderable array.
