protected function HtmlResponseAttachmentsProcessor::processFeed

protected HtmlResponseAttachmentsProcessor::processFeed($attached_feed)

Transform a 'feed' attachment into an 'html_head_link' attachment.

The RSS feed is a special case of 'html_head_link', so we just turn it into one.

Parameters

array $attached_feed: The ['#attached']['feed'] portion of a render array.

Return value

array An ['#attached']['html_head_link'] array, suitable for merging with another 'html_head_link' array.
