Detailed Description

Service for serializing entity data.

Note that we are using the API's serialization facility to ensure a consistent external representation of data entities. Using the ContentHandler to serialize the entity would expose internal implementation details.

For RDF output, this relies on the RdfBuilder class.

Member Function Documentation

◆ addIncomingRedirects()

Wikibase\Repo\LinkedData\EntityDataSerializationService::addIncomingRedirects	(	EntityId	$targetId,
		?EntityRedirect	$followedRedirect,
		array	$incomingRedirects,
		RdfBuilder	$rdfBuilder
	)

private

Parameters

EntityId	$targetId
EntityRedirect \| null	$followedRedirect	The followed redirect, will be omitted from the output.
EntityId[]	$incomingRedirects
RdfBuilder	$rdfBuilder

◆ createApiSerializer()

Wikibase\Repo\LinkedData\EntityDataSerializationService::createApiSerializer ( $formatName )

private

Creates an API printer that can generate the given output format.

Parameters

string $formatName The desired serialization format, as a format name understood by ApiBase or RdfWriterFactory.

Returns: ApiFormatBase|null A suitable result printer, or null if the given format is not supported by the API.

◆ createRdfBuilder()

Wikibase\Repo\LinkedData\EntityDataSerializationService::createRdfBuilder	(	$format,
		$flavorName = `null`
	)

private

Creates an Rdf Serializer that can generate the given output format.

Parameters

string	$format	The desired serialization format, as a format name understood by ApiBase or RdfWriterFactory
string \| null	$flavorName	Flavor name (used for RDF output)

Returns: RdfBuilder|null A suitable result printer, or null if the given format is not supported.

◆ generateApiResult()

Wikibase\Repo\LinkedData\EntityDataSerializationService::generateApiResult	(	EntityRevision	$entityRevision,
		ApiFormatBase	$printer
	)

private

Pushes the given $entity into the ApiResult held by the ApiMain module returned by newApiMain().

Calling $printer->execute() later will output this result, if $printer was generated from that same ApiMain module, as createApiPrinter() does.

Parameters

EntityRevision	$entityRevision	The entity to convert ot an ApiResult
ApiFormatBase	$printer	The output printer that will be used for serialization. Used to provide context for generating the ApiResult, and may also be manipulated to fine-tune the output.

Returns: ApiResult

◆ getApiSerialization()

Wikibase\Repo\LinkedData\EntityDataSerializationService::getApiSerialization	(	EntityRevision	$entityRevision,
		ApiFormatBase	$printer
	)

private

Serialize the entity data using the provided format.

Note that we are using the API's serialization facility to ensure a consistent external representation of data entities. Using the ContentHandler to serialize the entity would expose internal implementation details.

Parameters

EntityRevision	$entityRevision	the entity to output.
ApiFormatBase	$printer	the printer to use to generate the output

Returns: string the serialized data

◆ getFlavor()

Wikibase\Repo\LinkedData\EntityDataSerializationService::getFlavor ( $flavorName )

private

Get the producer setting for current data format.

Parameters

string | null $flavorName

Returns: int

Exceptions

MWException

◆ getSerializedData()

Wikibase\Repo\LinkedData\EntityDataSerializationService::getSerializedData	(		$format,
		EntityRevision	$entityRevision,
		RedirectRevision	$followedRedirect = `null`,
		array	$incomingRedirects = `[]`,
			$flavor = `null`
	)

Output entity data.

Parameters

string	$format	The name (mime type of file extension) of the format to use
EntityRevision	$entityRevision	The entity
RedirectRevision \| null	$followedRedirect	The redirect that led to the entity, or null
EntityId[]	$incomingRedirects	Incoming redirects to include in the output
string \| null	$flavor	The type of the output provided by serializer

Returns: array tuple of ( $data, $contentType )

Exceptions

MWException

◆ newApiMain()

Wikibase\Repo\LinkedData\EntityDataSerializationService::newApiMain ( $format )

private

Returns an ApiMain module that acts as a context for the formatting and serialization.

Parameters

string $format The desired output format, as a format name that ApiBase understands.

Returns: ApiMain

◆ rdfSerialize()

Wikibase\Repo\LinkedData\EntityDataSerializationService::rdfSerialize	(	EntityRevision	$entityRevision,
		?RedirectRevision	$followedRedirect,
		array	$incomingRedirects,
		RdfBuilder	$rdfBuilder,
			$flavor = `null`
	)

private

Parameters

EntityRevision	$entityRevision
RedirectRevision \| null	$followedRedirect	a redirect leading to the entity for use in the output
EntityId[]	$incomingRedirects	Incoming redirects to include in the output
RdfBuilder	$rdfBuilder
string \| null	$flavor	The type of the output provided by serializer

Returns: string RDF
