### Question:
SPARQLUpdateDataBlockParser extends TriGParser { @Override protected void parseGraph() throws RDFParseException, RDFHandlerException, IOException { super.parseGraph(); skipOptionalPeriod(); } SPARQLUpdateDataBlockParser();  SPARQLUpdateDataBlockParser(ValueFactory valueFactory); @Override RDFFormat getRDFFormat(); boolean isAllowBlankNodes(); void setAllowBlankNodes(boolean allowBlankNodes); void setLineNumberOffset(int lineNumberOffset);  }### Answer:
@Test public void testParseGraph() throws RDFParseException, RDFHandlerException, IOException { SPARQLUpdateDataBlockParser parser = new SPARQLUpdateDataBlockParser(); String blocksToCheck[] = new String[] { "graph <u:g1> {<u:1> <p:1> 1 } . <u:2> <p:2> 2.", "graph <u:g1> {<u:1> <p:1> 1 .} . <u:2> <p:2> 2." }; for (String block : blocksToCheck) { parser.parse(new StringReader(block), "http: } }
