3. 11.x core/lib/Drupal/Core/Render/PlaceholderGenerator.php \Drupal\Core\Render\PlaceholderGenerator::shouldAutomaticallyPlaceholder()

Whether the given render array should be automatically placeholdered.

The render array should be placeholdered if its cacheability either has a cache context with too high cardinality, a cache tag with a too high invalidation rate, or a max-age that is too low. Either of these would make caching ineffective, and thus we choose to placeholder instead.

Parameters

array $element: The render array whose cacheability to analyze.

Return value

bool Whether the given render array's cacheability meets the placeholdering conditions.
