Details edit

Implementations should return false if they generate the category links, so the default link generation is skipped.

  • &$out: OutputPage instance (object)
  • $categories: associative array, keys are category names, values are category types ("normal" or "hidden")
  • &$links: array, intended to hold the result. Must be an associative array with category types as keys and arrays of HTML links as values.
