static RefreshLinks::fixLinksFromArticle	(	$id,
		$ns = `false`
	)

static

Run LinksUpdate for all links on a given page_id.

Parameters

int	$id	The page_id
int \| bool	$ns	Only fix links if it is in this namespace

RefreshLinks::fixRedirect ( $id )

private

Update the redirect entry for a given page.

This methods bypasses the "redirect" table to get the redirect target, and parses the page's content to fetch it. This allows to be sure that the redirect target is up to date and valid. This is particularly useful when modifying namespaces to be sure the entry in the "redirect" table points to the correct page and not to an invalid one.

Parameters

int $id The page ID to check

static RefreshLinks::intervalCond	(	IDatabase	$db,

staticprivate

Build a SQL expression for a closed interval (i.e.

BETWEEN).

By specifying a null $start or $end, it is also possible to create half-bounded or unbounded intervals using this function.

Parameters

IDatabase	$db	Database connection
string	$var	Field name
mixed	$start	First value to include or null
mixed	$end	Last value to include or null
