Class RDF4JParser

java.lang.Object

org.apache.commons.rdf.simple.experimental.AbstractRDFParser<RDF4JParser>

org.apache.commons.rdf.rdf4j.experimental.RDF4JParser

All Implemented Interfaces:

java.lang.Cloneable, RDFParser

public class RDF4JParser
extends AbstractRDFParser<RDF4JParser>

RDF4J-based parser.

This can handle the RDF syntaxes RDFSyntax.JSONLD, RDFSyntax.NQUADS, RDFSyntax.NTRIPLES, RDFSyntax.RDFXML, RDFSyntax.TRIG and RDFSyntax.TURTLE - additional syntaxes can be supported by including the corresponding rdf4j-rio-* module on the classpath.

Method Detail

createRDFTermFactory

protected RDF4J 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<RDF4JParser>

Returns:

A new RDF

prepareForParsing

protected RDF4JParser prepareForParsing()
                                 throws java.io.IOException,
                                        java.lang.IllegalStateException

Description copied from class: AbstractRDFParser

Prepare a clone of this RDFParser which have been checked and completed.

The returned clone will always have AbstractRDFParser.getTarget() and AbstractRDFParser.getRdfTermFactory() present.

If the AbstractRDFParser.getSourceFile() is present, but the AbstractRDFParser.getBase() is not present, the base will be set to the file:/// IRI for the Path's real path (e.g. resolving any symbolic links).

Overrides:

prepareForParsing in class AbstractRDFParser<RDF4JParser>

Returns:

A completed and checked clone of this RDFParser

Throws:

java.io.IOException - If the source was not accessible (e.g. a file was not found)

java.lang.IllegalStateException - If the parser was not in a compatible setting (e.g. contentType was an invalid string)

parseSynchronusly

protected void parseSynchronusly()
                          throws java.io.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<RDF4JParser>

Throws:

java.io.IOException - If the source could not be read

getParserConfig

public org.eclipse.rdf4j.rio.ParserConfig getParserConfig()

Get the RDF4J ParserConfig to use.

If no parser config is set, the default configuration is provided.

Note: The parser config is mutable - changes in the returned config is reflected in this instance of the parser. To avoid mutation, create a new ParserConfig and set setParserConfig(ParserConfig).

Returns:

The RDF4J ParserConfig

setParserConfig

public void setParserConfig(org.eclipse.rdf4j.rio.ParserConfig parserConfig)

Set an RDF4J ParserConfig to use

Parameters:

parserConfig - Parser configuration

makeRDFHandler

protected org.eclipse.rdf4j.rio.RDFHandler makeRDFHandler()
