countDependencies()

SMW\SQLStore\QueryDependency\QueryDependencyLinksStore::countDependencies

(

$id

)

Since

Parameters

integer | array

$id

Returns

integer

findDependencyTargetLinks()

SMW\SQLStore\QueryDependency\QueryDependencyLinksStore::findDependencyTargetLinks	(	array	$idlist,
		RequestOptions	$requestOptions
	)

Finds a partial list (given limit and offset) of registered subjects that that represent a dependency on something like a subject in a query list, a property, or a printrequest.

s_id contains the subject id that links to the query that fulfills one of the conditions cited above.

Prefetched Ids are turned into a hash list that can later be split into chunks to work either in online or batch mode without creating a huge memory foothold.

Note

Select a list is crucial for performance as any selectRow would / single Id select would strain the system on large list connected to a query

Parameters

array	$idlist
