__construct()

Wikibase\Repo\Rdf\Values\ComplexValueRdfHelper::__construct	(	RdfVocabulary	$vocabulary,

RdfWriter	$valueNodeWriter
DedupeBag | null	$dedupeBag

Member Function Documentation

attachValueNode()

Wikibase\Repo\Rdf\Values\ComplexValueRdfHelper::attachValueNode	(	RdfWriter	$writer,
			$propertyValueNamespace,
			$propertyValueLName,
			$dataType,
			$snakNamespace,
		DataValue	$value,
			$normalized = false
	)

Creates a value node for $value, and attaches it to the current subject of $writer.

If a value node for $value was already created, null is returned. Otherwise, the value node's lname is returned, which should be used to generate detailed about the value into the writer returned by getValueNodeWriter().

When this method returns a non-null lname, the current subject of the RdfWriter returned by getValueNodeWriter() will the be value node with that lname.

Parameters

RdfWriter	$writer
string	$propertyValueNamespace	Property value relation namespace
string	$propertyValueLName	Property value relation name
string	$dataType	Property data type (unused, passed here for symmetry with the signature of ValueSnakRdfBuilder::addValue).
DataValue	$value
bool	$normalized	Is this a normalized value?

Returns

string|null The LName of the value node (in the RdfVocabulary::NS_VALUE namespace), or null if the value node should not be processed (generally, because it already has been processed).

getValueNodeWriter()

Wikibase\Repo\Rdf\Values\ComplexValueRdfHelper::getValueNodeWriter

Returns

RdfWriter
