Alter the results of the entity build array.

This hook is called after the content has been assembled in a structured array and may be used for doing processing which requires that the complete entity content structure has been built.

If a module wishes to act on the rendered HTML of the entity rather than the structured content array, it may use this hook to add a #post_render callback. Alternatively, it could also implement hook_preprocess_HOOK() for the particular entity type template, if there is one (e.g., node.html.twig).

See the Default theme implementations topic and \Drupal\Core\Render\RendererInterface::render() for details.

Parameters

array &$build: A renderable array representing the entity content.

\Drupal\Core\Entity\EntityInterface $entity: The entity object being rendered.

\Drupal\Core\Entity\Display\EntityViewDisplayInterface $display: The entity view display holding the display options configured for the entity components.
