JsonLdSerializer
in package
implements
SerializerInterface
Thin wrapper providing RdfInterface\Serializer API for JSON-LD the parser provided by the ml/json-ld library.
Be aware the implementation provided by the ml/json-ld library is not really focused on performance. If you value speed and/or low memory footprint consider using other serialization format.

public
__construct([string $baseUri = null ][, int $transform = self::TRANSFORM_NONE ][, int $jsonEncodeFlags = JSON_UNESCAPED_SLASHES ][, mixed $context = null ][, array<string, mixed> $options = [] ]) : mixed
Parameters
- $baseUri : string = null
- $transform : int = self::TRANSFORM_NONE
-
transformation to be applied before serializing to string. One of
JsonLdSerializer::TRANSFORM_NONE(default),JsonLdSerializer::TRANSFORM_EXPAND,JsonLdSerializer::TRANSFORM_FLATTENorJsonLdSerializer::TRANSFORM_COMPACT. In case ofJsonLdSerializer::TRANSFORM_COMPACTthe$contextparameter has to be provided. - $jsonEncodeFlags : int = JSON_UNESCAPED_SLASHES
-
flags to be passed to the
json_encode()call serializing output to a string - see https://www.php.net/manual/en/function.json-encode.php . - $context : mixed = null
-
context to be passed to
ML\JsonLD\JsonLD::compact()orML\JsonLD\JsonLD::flatten()when$transformequalsJsonLdSerializer::TRANSFORM_COMPACTorJsonLdSerializer::TRANSFORM_FLATTEN, repectively. - $options : array<string, mixed> = []
-
options to be passed to the corresponding
ML\JsonLD\JsonLDmethod (expand(),compact()orflatten()according to the$transformparameter value). If you would like these methods to be better documented, then you are not then only one... :-(

serialize()
public
serialize(Traversable<string|int, QuadInterface>|array<string|int, QuadInterface> $graph[, RdfNamespaceInterface|null $nmsp = null ]) : string
Parameters
- $graph : Traversable<string|int, QuadInterface>|array<string|int, QuadInterface>
- $nmsp : RdfNamespaceInterface|null = null
-
If passed, it's used for compacting the output. Unfortunately only property URIs can be compacted that way (of course for that full property URIs must be registered as "namespaces").

stringserializeStream()
public
serializeStream(mixed $output, Traversable<string|int, QuadInterface>|array<string|int, QuadInterface> $graph[, RdfNamespaceInterface|null $nmsp = null ]) : void
Parameters
- $output : mixed
- $graph : Traversable<string|int, QuadInterface>|array<string|int, QuadInterface>
- $nmsp : RdfNamespaceInterface|null = null
-
unused but required for compatibility with the
\rdfInterface\Serializer.
