Constructor Details

JSONLDParser

public JSONLDParser()

Default constructor

JSONLDParser

public JSONLDParser(ValueFactory valueFactory)

Creates a JSONLD Parser using the given ValueFactory to create new Values.

Parameters:

valueFactory - The ValueFactory to use

Method Details

getRDFFormat

public RDFFormat getRDFFormat()

Description copied from interface: RDFParser

Gets the RDF format that this parser can parse.

getSupportedSettings

public Collection<RioSetting<?>> getSupportedSettings()

Specified by:

getSupportedSettings in interface RDFParser

Overrides:

getSupportedSettings in class AbstractRDFParser

Returns:

A collection of RioSettings that are supported by this RDFParser.

parse

public void parse(InputStream in,
 String baseURI)
           throws IOException,
RDFParseException,
RDFHandlerException

Description copied from interface: RDFParser

Parses the data from the supplied InputStream, using the supplied baseURI to resolve any relative URI references.

Parameters:

in - The InputStream from which to read the data.

baseURI - The URI associated with the data in the InputStream. May be null. Parsers for syntax formats that do not support relative URIs will ignore this argument.

Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler has encountered an unrecoverable error.

parse

public void parse(Reader reader,
 String baseURI)
           throws IOException,
RDFParseException,
RDFHandlerException

Description copied from interface: RDFParser

Parses the data from the supplied Reader, using the supplied baseURI to resolve any relative URI references.

Parameters:

reader - The Reader from which to read the data.

baseURI - The URI associated with the data in the InputStream. May be null. Parsers for syntax formats that do not support relative URIs will ignore this argument.

Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler has encountered an unrecoverable error.

protected no.hasmac.jsonld.document.Document getDocument(InputStream in,
 Reader reader)
                                                  throws no.hasmac.jsonld.JsonLdError,
