protected function WebTestBase::drupalBuildEntityView in Zircon Profile 8.0

Same name and namespace in other branches

1. 8 core/modules/simpletest/src/WebTestBase.php \Drupal\simpletest\WebTestBase::drupalBuildEntityView()

Builds the renderable view of an entity.

Entities postpone the composition of their renderable arrays to #pre_render functions in order to maximize cache efficacy. This means that the full renderable array for an entity is constructed in drupal_render(). Some tests require the complete renderable array for an entity outside of the drupal_render process in order to verify the presence of specific values. This method isolates the steps in the render process that produce an entity's renderable array.

Parameters

\Drupal\Core\Entity\EntityInterface $entity: The entity to prepare a renderable array for.

string $view_mode: (optional) The view mode that should be used to build the entity.

null $langcode: (optional) For which language the entity should be prepared, defaults to the current content language.

bool $reset: (optional) Whether to clear the cache for this entity.

Return value

array
