public function RendererInterface::addCacheableDependency in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 core/lib/Drupal/Core/Render/RendererInterface.php \Drupal\Core\Render\RendererInterface::addCacheableDependency()

Adds a dependency on an object: merges its cacheability metadata.

E.g. when a render array depends on some configuration, an entity, or an access result, we must make sure their cacheability metadata is present on the render array. This method makes doing that simple.

Parameters

array &$elements: The render array to update.

\Drupal\Core\Cache\CacheableDependencyInterface|mixed $dependency: The dependency. If the object implements CacheableDependencyInterface, then its cacheability metadata will be used. Otherwise, the passed in object must be assumed to be uncacheable, so max-age 0 is set.
