Protected Member Functions inherited from MediaWiki\Deferred\LinksUpdate\GenericPageLinksTable

deduplicateLinkIds ( $linkIds)

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>

deleteLink ( $linkId)

Delete a link identified by ID.The subclass is expected to queue the deletion by calling deleteRow().

Parameters

mixed $linkId

fetchExistingRows ()

Do a select query to fetch the existing rows.

getExistingFields ()

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 ()

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>

getNewLinkIDs ()

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>

insertLink ( $linkId)

Insert a link identified by ID.The subclass is expected to queue the insertion by calling insertRow().

Parameters

mixed $linkId

isExisting ( $linkId)

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

Parameters

mixed $linkId

Returns: bool

isInNewSet ( $linkId)

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

Parameters

mixed $linkId

Returns: bool

makePageReferenceValue ( $linkId)

Convert a link ID to a PageReferenceValue.

Parameters

mixed $linkId

Returns: PageReferenceValue

makeTitle ( $linkId)

Convert a link ID to a Title.

Stability: stable: to override

Parameters

mixed $linkId

Returns: Title

needForcedLinkRefresh ()

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

Protected Member Functions inherited from MediaWiki\Deferred\LinksUpdate\TitleLinksTable

getDeduplicatedLinkIds ( $setType)

Get link IDs for a given set type, filtering out duplicate links to the same title.

Protected Member Functions inherited from MediaWiki\Deferred\LinksUpdate\LinksTable

deleteRow ( $conds)

Queue a deletion operation.

doWrites ()

Do the common DB operations.

finishUpdate ()

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

getBatchSize ()

Get the maximum number of rows to update in a batch.

getDB ()

getFromConds ()

Get field=>value associative array for the from field(s)

getInsertOptions ()

Get the options for the insert queries.

getLBFactory ()

getLinkIDs ( $setType)

Get an array or iterator of link IDs of a given type.

getMovedPage ()

Assuming the page was moved, get the original page title before the move.

getRevision ()

Get the RevisionRecord of the new revision, if the LinksUpdate caller injected one.

getSourcePage ()

Get the source page, i.e.

getSourcePageId ()

Get the page_id of the source page.

getTransactionTicket ()

Get the empty transaction ticket, or null if there is none.

insertRow ( $row)

Queue a row for insertion.

isCrossNamespaceMove ()

Determine whether the page was moved to a different namespace.

isMove ()

Determine whether the page was moved.

startUpdate ()

Subclasses can override this to do any necessary setup before individual write operations begin.
