◆ addResultToCache()

LinkBatch::addResultToCache	(	$cache,
		$res
	)

Add a result wrapper containing IDs and titles to a LinkCache object.

As normal, titles will go into the static Title cache field. This function also stores extra fields of the title used for link parsing to avoid extra DB queries.

Parameters

LinkCache	$cache
IResultWrapper	$res

Returns: array Array of remaining titles

◆ constructSet()

LinkBatch::constructSet	(	$prefix,
		$db
	)

Construct a WHERE clause which will match all the given titles.

Parameters

string	$prefix	The appropriate table's field name prefix ('page', 'pl', etc)
IDatabase	$db	DB object to use

Returns: string|bool String with SQL where clause fragment, or false if no items.
