All Implemented Interfaces:

RDFParser

public class NDJSONLDParser
extends JSONLDParser

Introduce a parser capable of parsing Newline Delimited JSON-LD, where each line is a serialized JSON-LD record. The format is inspired by Newline Delimited JSON formathttp://ndjson.org/. Even though each line is a separate JSON-LD document, the whole document is treated as a single RDF document, having one single BNodes context to preserve BNodes identifiers.

Constructor Details

NDJSONLDParser

public NDJSONLDParser()

Default constructor

NDJSONLDParser

public NDJSONLDParser(ValueFactory valueFactory)

Creates a RDF4J NDJSONLD 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.

Specified by:

getRDFFormat in interface RDFParser

Overrides:

getRDFFormat in class JSONLDParser

getJSONObject

protected Object getJSONObject(InputStream in,
 Reader reader,
 com.fasterxml.jackson.core.JsonFactory factory)
                        throws IOException

Overrides:

getJSONObject in class JSONLDParser

Throws:

IOException

parse

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

Description copied from interface: RDFParser

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

Specified by:

parse in interface RDFParser

Overrides:

parse in class JSONLDParser

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:

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

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

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