Example 1 with PartialParsingPointers

use of org.eclipse.xtext.parser.impl.PartialParsingPointers in project xtext-core by eclipse.

the class PartialParsingPointerLookaheadTest method testLookahead_9_14.

@Test
public void testLookahead_9_14() throws Exception {

    for (int i = 9; i < 15; ++i) {
        PartialParsingPointers parsingPointers = calculatePartialParsingPointers(model, i, 1);
        // actual expecation would lead to yet more complexity in partial
        // parser
        // checkParseRegionPointers(parsingPointers, " foo bar c b d", "RuleCall", "Alts");
        checkParseRegionPointers(parsingPointers, model, "ParserRule", "Entry");
    }
