Member Function Documentation

◆ deduplicateLinkIds()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::deduplicateLinkIds ( $linkIds )

protected

Given an iterator over link IDs, remove links which go to the same title, leaving only one link per title.

Parameters

iterable<mixed> $linkIds

Returns: iterable<mixed>

Reimplemented from MediaWiki\Deferred\LinksUpdate\TitleLinksTable.

Definition at line 103 of file ImageLinksTable.php.

◆ deleteLink()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::deleteLink ( $linkId )

protected

Delete a link identified by ID.

The subclass is expected to queue the deletion by calling deleteRow().

Parameters

mixed $linkId

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 91 of file ImageLinksTable.php.

References MediaWiki\Deferred\LinksUpdate\LinksTable\deleteRow().

◆ finishUpdate()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::finishUpdate ( )

protected

Subclasses can override this to do any updates associated with their link data, for example dispatching HTML update jobs.

Stability: stable: to override

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 110 of file ImageLinksTable.php.

◆ getExistingFields()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::getExistingFields ( )

protected

Get the fields to be used in fetchExistingRows().

Note that fetchExistingRows() is just a helper for subclasses. The value returned here is effectively private to the subclass.

Returns: array

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 41 of file ImageLinksTable.php.

◆ getExistingLinkIDs()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::getExistingLinkIDs ( )

protected

Get an array (or iterator) of link IDs for the existing state.

The subclass should load the data from the database. There is fetchExistingRows() to make this easier but the subclass is responsible for caching.

See the LinksTable doc comment for an explanation of link IDs.

Returns: iterable<mixed>

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 66 of file ImageLinksTable.php.

◆ getFromField()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::getFromField ( )

protected

Get the name of the field which links to page_id.

Returns: string

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 37 of file ImageLinksTable.php.

◆ getNewLinkIDs()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::getNewLinkIDs ( )

protected

Get an array (or iterator) of link IDs for the new state.

See the LinksTable doc comment for an explanation of link IDs.

Returns: iterable<mixed>

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 45 of file ImageLinksTable.php.

◆ getTableName()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::getTableName ( )

protected

Get the table name.

Returns: string

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 33 of file ImageLinksTable.php.

◆ insertLink()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::insertLink ( $linkId )

protected

Insert a link identified by ID.

The subclass is expected to queue the insertion by calling insertRow().

Parameters

mixed $linkId

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 84 of file ImageLinksTable.php.

References MediaWiki\Deferred\LinksUpdate\LinksTable\getSourcePage(), and MediaWiki\Deferred\LinksUpdate\LinksTable\insertRow().

◆ isExisting()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::isExisting ( $linkId )

protected

Determine whether a link (from the new set) is in the existing set.

Parameters

mixed $linkId

Returns: bool

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 72 of file ImageLinksTable.php.

◆ isInNewSet()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::isInNewSet ( $linkId )

protected

Determine whether a link (from the existing set) is in the new set.

Parameters

mixed $linkId

Returns: bool

Definition at line 76 of file ImageLinksTable.php.

◆ makePageReferenceValue()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::makePageReferenceValue ( $linkId )

protected

Convert a link ID to a PageReferenceValue.

Parameters

mixed $linkId

Returns: PageReferenceValue

Definition at line 95 of file ImageLinksTable.php.

◆ makeTitle()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::makeTitle ( $linkId )

protected

Convert a link ID to a Title.

Stability: stable: to override

Parameters

mixed $linkId

Returns: Title

Reimplemented from MediaWiki\Deferred\LinksUpdate\TitleLinksTable.

Definition at line 99 of file ImageLinksTable.php.

◆ needForcedLinkRefresh()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::needForcedLinkRefresh ( )

protected

Subclasses can override this to return true in order to force reinsertion of all the links due to some property of the link changing for reasons not represented by the link ID.

Returns: bool

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 80 of file ImageLinksTable.php.

References MediaWiki\Deferred\LinksUpdate\LinksTable\isCrossNamespaceMove().

◆ setParserOutput()

MediaWiki\Deferred\LinksUpdate\ImageLinksTable::setParserOutput ( ParserOutput $parserOutput )

Subclasses should implement this to extract the data they need from the ParserOutput.

To support a future refactor of LinksDeletionUpdate, if this method is not called, the subclass should assume that the new state is empty.

Parameters

ParserOutput $parserOutput

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.
