3. 11.x core/lib/Drupal/Core/Render/PlaceholderingRenderCache.php \Drupal\Core\Render\PlaceholderingRenderCache::createPlaceholderAndRemember()

Create a placeholder for a renderable array and remember in a static cache.

Parameters

array $rendered_elements: A fully rendered renderable array.

array $pre_bubbling_elements: A renderable array corresponding to the state (in particular, the cacheability metadata) of $rendered_elements prior to the beginning of its rendering process, and therefore before any bubbling of child information has taken place. Only the #cache property is used by this function, so the caller may omit all other properties and children from this array.

Return value
