Same name and namespace in other branches

9 core/modules/layout_builder/src/QuickEditIntegration.php \Drupal\layout_builder\QuickEditIntegration::entityViewAlter()

Alters the entity view build for Quick Edit compatibility.

When rendering fields outside of normal view modes, Quick Edit requires that modules identify themselves with a view mode ID in the format [module_name]-[information the module needs to rerender], as prescribed by hook_quickedit_render_field().

Parameters

array $build: The built entity render array.

\Drupal\Core\Entity\EntityInterface $entity: The entity.

\Drupal\Core\Entity\Display\EntityViewDisplayInterface $display: The entity view display.
