JsonLdParser

public JsonLdParser()

Method Details

createRDFTermFactory

protected JsonLdRDF createRDFTermFactory()

Description copied from class: AbstractRDFParser

Create a new RDF for a parse session.

This is called by AbstractRDFParser.parse() to set AbstractRDFParser.rdfTermFactory(RDF) if it is Optional.empty().

As parsed blank nodes might be made with RDF.createBlankNode(String), each call to this method SHOULD return a new RDF instance.

Overrides:

createRDFTermFactory in class AbstractRDFParser<JsonLdParser>

Returns:

A new RDF

contentType

public JsonLdParser contentType(RDFSyntax rdfSyntax)
                         throws IllegalArgumentException

Description copied from interface: RDFParser

Specify the content type of the RDF syntax to parse.

This option can be used to select the RDFSyntax of the source, overriding any Content-Type headers or equivalent.

The character set of the RDFSyntax is assumed to be StandardCharsets.UTF_8 unless overridden within the document (e.g. <?xml version="1.0" encoding="iso-8859-1"?> in RDFSyntax.RDFXML).

This method will override any contentType set with RDFParser.contentType(String).

Specified by:

contentType in interface RDFParser

Overrides:

contentType in class AbstractRDFParser<JsonLdParser>

Parameters:

rdfSyntax - An RDFSyntax to parse the source according to, e.g. RDFSyntax.TURTLE.

Returns:

An RDFParser that will use the specified content type.

Throws:

IllegalArgumentException - If this RDFParser does not support the specified RDFSyntax.

See Also:

• RDFParser.contentType(String)

contentType

public JsonLdParser contentType(String contentType)
                         throws IllegalArgumentException

Description copied from interface: RDFParser

Specify the content type of the RDF syntax to parse.

This option can be used to select the RDFSyntax of the source, overriding any Content-Type headers or equivalent.

The content type MAY include a charset parameter if the RDF media types permit it; the default charset is StandardCharsets.UTF_8 unless overridden within the document.

This method will override any contentType set with RDFParser.contentType(RDFSyntax).

Specified by:

contentType in interface RDFParser

Overrides:

contentType in class AbstractRDFParser<JsonLdParser>

Parameters:

contentType - A content-type string, e.g. application/ld+json or text/turtle;charset="UTF-8" as specified by RFC7231.

Returns:

An RDFParser that will use the specified content type.

Throws:

IllegalArgumentException - If the contentType has an invalid syntax, or this RDFParser does not support the specified contentType.

See Also:

• RDFParser.contentType(RDFSyntax)

asURL

private static URL asURL(IRI iri)
                  throws IllegalStateException

Throws:

IllegalStateException

checkSource

protected void checkSource()
                    throws IOException

Description copied from class: AbstractRDFParser

Check that one and only one source is present and valid.

Used by AbstractRDFParser.parse().

Subclasses might override this method, e.g. to support other source combinations, or to check if the sourceIri is resolvable.

Overrides:

checkSource in class AbstractRDFParser<JsonLdParser>

Throws:

IOException - If a source file can't be read

parseSynchronusly

protected void parseSynchronusly()
                          throws IOException

Description copied from class: AbstractRDFParser

Parse AbstractRDFParser.sourceInputStream, AbstractRDFParser.sourceFile or AbstractRDFParser.sourceIri.

One of the source fields MUST be present, as checked by AbstractRDFParser.checkSource().

AbstractRDFParser.checkBaseRequired() is called to verify if AbstractRDFParser.getBase() is required.

Specified by:

parseSynchronusly in class AbstractRDFParser<JsonLdParser>

Throws:

IOException - If the source could not be read

getJsonLdFactory

private JsonLdRDF getJsonLdFactory()

readSource

private Object readSource()
                   throws IOException

Throws:

IOException
