Bug: T228988
Change-Id: I89966321ec3b4feb5a59e06b8a656d76c4bd9ef2
* 'content'- whether the actual content of the slots should be
* preloaded.
* @param int $queryFlags
- * @param Title|null $title
+ * @param Title|null $title The title to which all the revision rows belong, if there
+ * is such a title and the caller has it handy, so we don't have to look it up again.
+ * If this parameter is given and any of the rows has a rev_page_id that is different
+ * from $title->getArticleID(), an InvalidArgumentException is thrown.
+ *
* @return StatusValue a status with a RevisionRecord[] of successfully fetched revisions
* and an array of errors for the revisions failed to fetch.
