Examples of org.apache.jena.riot.ReaderRIOT

org.apache.jena.riot.ReaderRIOT
Interface to parsing processes that takes an input stream and emit items. The "read" operation may be called repeatedly for a single ReaderRIOT, with different arguments. The StreamRDF destination would have to cope with concurrent operation if these read operations overlap.

            s = InfFactory.inf(s, setup) ;
        
        StreamRDFCounting sink = StreamRDFLib.count(s) ;
        s = null ;
        
        ReaderRIOT reader = RDFDataMgr.createReader(lang) ;
        try {
            if ( checking ) {
                if ( lang == RDFLanguages.NTRIPLES || lang == RDFLanguages.NQUADS )
                    reader.setParserProfile(RiotLib.profile(baseURI, false, true, errHandler)) ;
                else
                    reader.setParserProfile(RiotLib.profile(baseURI, true, true, errHandler)) ;
            } else
                reader.setParserProfile(RiotLib.profile(baseURI, false, false, errHandler)) ;


            if ( labelsAsGiven )
                reader.getParserProfile().setLabelToNode(LabelToNode.createUseLabelAsGiven()) ;
            modTime.startTimer() ;
            reader.read(in, baseURI, ct, sink, null) ;
        } catch (RiotException ex) {
            // Should have handled the exception and logged a message by now.
            // System.err.println("++++"+ex.getMessage());
