Member Function Documentation

◆ add()

MediaWiki\Page\LinkBatch::add	(		$ns,
			$dbkey )

Parameters

int	$ns
string	$dbkey

Definition at line 186 of file LinkBatch.php.

◆ addObj()

MediaWiki\Page\LinkBatch::addObj ( $link )

Parameters

LinkTarget | PageReference $link

◆ addResultToCache()

MediaWiki\Page\LinkBatch::addResultToCache	(		$cache,
			$res )

Add a database result with page rows to the LinkCache.

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: int[] Remaining unknown titles from PDBK to ID

Definition at line 277 of file LinkBatch.php.

◆ addUser()

MediaWiki\Page\LinkBatch::addUser ( UserIdentity $user )

Add user page and user talk page for a given user to this batch.

Calling execute will also prefetch the expiration status of temporary accounts added this way, which is needed for the efficient rendering of user links via UserLinkRenderer.

Since: 1.44

Definition at line 150 of file LinkBatch.php.

◆ constructSet()

MediaWiki\Page\LinkBatch::constructSet	(		$prefix,
			$db )

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

It is the caller's responsibility to only call this if the LinkBatch is not empty, because there is no safe way to represent a SQL conditional for the empty set.

Parameters

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

Returns: string String with SQL where clause fragment

Definition at line 390 of file LinkBatch.php.

MediaWiki\Page\LinkBatch::doGenderQuery ( )

Execute and cache {{GENDER:...}} information for user pages in this LinkBatch.

Returns: bool Whether the query was successful

Definition at line 369 of file LinkBatch.php.

◆ doQuery()

MediaWiki\Page\LinkBatch::doQuery ( )

◆ execute()

MediaWiki\Page\LinkBatch::execute ( )

Do the query and add the results to the LinkCache.

Returns: int[] Remaining unknown titles from PDBK to ID

Definition at line 228 of file LinkBatch.php.

◆ executeInto()

MediaWiki\Page\LinkBatch::executeInto ( $cache )

protected

Do the query and add the results to a given LinkCache object.

Parameters

LinkCache $cache

Definition at line 253 of file LinkBatch.php.

◆ getPageIdentities()

MediaWiki\Page\LinkBatch::getPageIdentities ( )

Do the query, add the results to the LinkCache object, and return ProperPageIdentity instances corresponding to the pages in the batch.

Since: 1.37

Returns: ProperPageIdentity[] A list of ProperPageIdentities

Definition at line 239 of file LinkBatch.php.

◆ getSize()
