public PlaceholderGenerator::shouldAutomaticallyPlaceholder(array $element)
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.
