		EntityRdfBuilderFactory	$entityRdfBuilderFactory,
		int	$flavor,
		RdfWriter	$writer,
		DedupeBag	$dedupeBag,

Member Function Documentation

◆ addDumpHeader()

Wikibase\Repo\Rdf\RdfBuilder::addDumpHeader ( int $timestamp = 0 )

Create header structure for the dump (this makes RdfProducer::PRODUCE_VERSION_INFO redundant)

Parameters

int $timestamp Timestamp (for testing)

◆ addEntity()

Wikibase\Repo\Rdf\RdfBuilder::addEntity ( EntityDocument $entity )

Add an entity to the RDF graph, including all supported structural components of the entity and its sub entities.

Parameters

EntityDocument $entity the entity to output.

Implements Wikibase\Repo\Rdf\EntityRdfBuilder.

◆ addEntityMetaData()

Wikibase\Repo\Rdf\RdfBuilder::addEntityMetaData ( EntityId $entityId )

private

Adds meta-information about an entity id (such as the ID and type) to the RDF graph.

Todo: extract into MetaDataRdfBuilder

◆ addEntityPageProps()

Wikibase\Repo\Rdf\RdfBuilder::addEntityPageProps ( EntityDocument $entity )

Add page props information.

To ensure consistent data, this recalculates the page props from the entity content; it does not actually query the page_props table.

◆ addEntityRedirect()

Wikibase\Repo\Rdf\RdfBuilder::addEntityRedirect	(	EntityId	$from,
		EntityId	$to )

Declares $from to be an alias for $to, using the owl:sameAs relationship.

◆ addEntityRevisionInfo()

Wikibase\Repo\Rdf\RdfBuilder::addEntityRevisionInfo	(	EntityId	$entityId,
		int	$revision,
		string	$timestamp )

Adds revision information about an entity's revision to the RDF graph.

Todo: extract into MetaDataRdfBuilder

Parameters

EntityId	$entityId
int	$revision
string	$timestamp	in TS_MW format

◆ addEntityStub()

Wikibase\Repo\Rdf\RdfBuilder::addEntityStub ( EntityId $entityId )

Adds stub information for the given EntityId to the RDF graph.

Stub information means meta information and labels.

Implements Wikibase\Repo\Rdf\EntityStubRdfBuilder.

◆ addQueuedEntities()

Wikibase\Repo\Rdf\RdfBuilder::addQueuedEntities ( )

private

Add the RDF serialization of all entities in the entitiesToOutput queue.

◆ addSingleEntity()

Wikibase\Repo\Rdf\RdfBuilder::addSingleEntity ( EntityDocument $entity )

private

Add a single entity to the RDF graph, including all supported structural components of the entity.

Parameters

EntityDocument $entity the entity to output.

◆ entityReferenceMentioned()

Wikibase\Repo\Rdf\RdfBuilder::entityReferenceMentioned ( EntityId $id )

See also: EntityMentionListener::entityReferenceMentioned

Implements Wikibase\Repo\Rdf\EntityMentionListener.

◆ entityResolved()

Wikibase\Repo\Rdf\RdfBuilder::entityResolved ( EntityId $entityId )

private

Registers an entity as resolved.

◆ entityToResolve()

Wikibase\Repo\Rdf\RdfBuilder::entityToResolve ( EntityId $entityId )

private

Registers an entity as mentioned.

Will be recorded as unresolved if it wasn't already marked as resolved.

◆ finishDocument()

Wikibase\Repo\Rdf\RdfBuilder::finishDocument ( )

Finish writing the document After that, nothing should ever be written into the document.

◆ getNamespaces()

Wikibase\Repo\Rdf\RdfBuilder::getNamespaces ( )

Returns a map of namespace names to URIs.

◆ getPagePropertyDefs()

Wikibase\Repo\Rdf\RdfBuilder::getPagePropertyDefs ( )

Get map of page properties used by this builder.

Returns: string[][]

◆ getRDF()

Wikibase\Repo\Rdf\RdfBuilder::getRDF ( )

Returns the RDF generated by the builder.

◆ markStubEntityDataForPrefetching()

Wikibase\Repo\Rdf\RdfBuilder::markStubEntityDataForPrefetching ( array $entityIds )

private

◆ propertyMentioned()

Wikibase\Repo\Rdf\RdfBuilder::propertyMentioned ( PropertyId $id )

See also: EntityMentionListener::propertyMentioned

Implements Wikibase\Repo\Rdf\EntityMentionListener.

◆ resolveMentionedEntities()

Wikibase\Repo\Rdf\RdfBuilder::resolveMentionedEntities ( )

Add stubs for any entities that were previously mentioned (e.g.

as properties or data values).

◆ shouldProduce()

Wikibase\Repo\Rdf\RdfBuilder::shouldProduce ( int $what )

private

Should we produce this aspect?

◆ startDocument()

Wikibase\Repo\Rdf\RdfBuilder::startDocument ( )

Start writing RDF document Note that this builder does not have to finish it, it may be finished later.

◆ subEntityMentioned()

Wikibase\Repo\Rdf\RdfBuilder::subEntityMentioned ( EntityDocument $entity )

See also: EntityMentionListener::subEntityMentioned

Implements Wikibase\Repo\Rdf\EntityMentionListener.
