Detailed Description

Shared code for pagelinks and templatelinks.

They are very similar tables since they both link to an arbitrary page identified by namespace and title.

Link ID format: string[]:

0: namespace ID
1: title DB key

Since: 1.38

Member Function Documentation

◆ deduplicateLinkIds()

MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable::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 179 of file GenericPageLinksTable.php.

◆ deleteLink()

MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable::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 151 of file GenericPageLinksTable.php.

References SCHEMA_COMPAT_WRITE_NEW, and SCHEMA_COMPAT_WRITE_OLD.

◆ fetchExistingRows()

MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable::fetchExistingRows ( )

protected

Do a select query to fetch the existing rows.

This is a helper for subclasses.

Returns: IResultWrapper

Reimplemented from MediaWiki\Deferred\LinksUpdate\LinksTable.

Definition at line 92 of file GenericPageLinksTable.php.

References MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable\getTargetIdField().

◆ getExistingFields()

MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable::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

◆ getExistingLinkIDs()

MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable::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.
