public class SPARQLStarResultsTSVWriter
extends SPARQLResultsTSVWriter

Writer for SPARQL-star TSV results. This is equivalent to the SPARQL TSV writer with the addition of support for RDF-star triples. Triples will be serialized in Turtle-star fashion with the notable exception that any embedded literals will not use the triple quotes notation (as regular literals in SPARQL TSV).
