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

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

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.
