Example 1 with LangNQuads

use of org.apache.jena.riot.lang.LangNQuads in project jena by apache.

the class SerializationFactoryFinder method quadSerializationFactory.

public static SerializationFactory<Quad> quadSerializationFactory() {
    return new SerializationFactory<Quad>() {

        @Override
        public Sink<Quad> createSerializer(OutputStream out) {
            return new SinkQuadOutput(out, null, NodeToLabel.createBNodeByLabelEncoded());
        }

        @Override
        public Iterator<Quad> createDeserializer(InputStream in) {
            Tokenizer tokenizer = TokenizerFactory.makeTokenizerASCII(in);
            ParserProfile profile = RiotLib.createParserProfile(RiotLib.factoryRDF(LabelToNode.createUseLabelEncoded()), ErrorHandlerFactory.errorHandlerNoWarnings, IRIResolver.createNoResolve(), false);
            LangNQuads parser = new LangNQuads(tokenizer, profile, null);
            return parser;
        }

        @Override
        public long getEstimatedMemorySize(Quad item) {
            // TODO
            return 0;
        }
    };
