Class NQuadsParser

java.lang.Object

org.openrdf.rio.helpers.RDFParserBase

org.openrdf.rio.ntriples.NTriplesParser

org.openrdf.rio.nquads.NQuadsParser

All Implemented Interfaces:

RDFParser

public class NQuadsParser
extends NTriplesParser

RDF parser implementation for the N-Quads RDF format, extending the Rio N-Triples parser. A specification of N-Quads can be found here. This parser is not thread-safe, therefore its public methods are synchronized.

Method Detail

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 NTriplesParser

parse

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

Description copied from class: NTriplesParser

Implementation of the parse(InputStream, String) method defined in the RDFParser interface.

Specified by:

parse in interface RDFParser

Overrides:

parse in class NTriplesParser

Parameters:

inputStream - The InputStream from which to read the data, must not be null. The InputStream is supposed to contain 7-bit US-ASCII characters, as per the N-Triples specification.

baseURI - The URI associated with the data in the InputStream, must not be null.

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 encountered an unrecoverable error.

parse

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

Description copied from class: NTriplesParser

Implementation of the parse(Reader, String) method defined in the RDFParser interface.

Specified by:

parse in interface RDFParser

Overrides:

parse in class NTriplesParser

Parameters:

reader - The Reader from which to read the data, must not be null.

baseURI - The URI associated with the data in the Reader, must not be null.

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 encountered an unrecoverable error.

parseContext

protected int parseContext(int c)
                    throws IOException,
                           RDFParseException

Throws:

IOException
