A CentralIdLookup provider that just uses local IDs.
lookupUserNames(array $nameToId, $audience=self::AUDIENCE_PUBLIC, $flags=self::READ_NORMAL)
Given (local) user names, return the central IDs.
lookupCentralIds(array $idToName, $audience=self::AUDIENCE_PUBLIC, $flags=self::READ_NORMAL)
Given central user IDs, return the (local) user names.
isAttached(User $user, $wikiId=null)

this hook is for auditing only RecentChangesLinked and Watchlist RecentChangesLinked and Watchlist Do not use this to implement individual filters if they are compatible with the ChangesListFilter and ChangesListFilterGroup structure use sub classes of those in conjunction with the ChangesListSpecialPageStructuredFilters hook This hook can be used to implement filters that do not implement that or custom behavior that is not an individual filter e g Watchlist & $tables
