public function RenderCacheInterface::getCacheableRenderArray

public RenderCacheInterface::getCacheableRenderArray(array $elements)

Gets a cacheable render array for a render array and its rendered output.

Given a render array and its rendered output (HTML string), return an array data structure that allows the render array and its associated metadata to be cached reliably (and is serialization-safe).

If Drupal needs additional rendering metadata to be cached at some point, consumers of this method will continue to work. Those who only cache certain parts of a render array will cease to work.

Parameters

array $elements: A render array, on which \Drupal\Core\Render\RendererInterface::render() has already been invoked.

Return value

array An array representing the cacheable data for this render array.

core/lib/Drupal/Core/Render/RenderCacheInterface.php, line 33
