This is the same as the previous case except that the D prevents the B path from "pinching" together into a single NFA state. This test also demonstrates that just because B D could predict alt 1 in rule 'a', it is unnecessary to continue NFA->DFA conversion to include an edge for D. Alt 1 is the only possible prediction because we resolve the ambiguity by choosing alt 1. testLL_1_Pred public void testLL_1_Pred() throws Exception(Code) testLL_2_Pred public void testLL_2_Pred() throws Exception(Code) testLeftRecursivePred public void testLeftRecursivePred() throws Exception(Code) testLexerMatchesLongestThenTestPred public void testLexerMatchesLongestThenTestPred() throws Exception(Code) testMatchesLongestThenTestPred public void testMatchesLongestThenTestPred() throws Exception(Code) testORGatedPred public void testORGatedPred() throws Exception(Code) testOrPredicates public void testOrPredicates() throws Exception(Code) testPredGets2SymbolSyntacticContext public void testPredGets2SymbolSyntacticContext() throws Exception(Code) testPredWithArbitraryLookahead public void testPredWithArbitraryLookahead() throws Exception(Code) testPredWithK1 public void testPredWithK1() throws Exception(Code) testPredicatedLoop public void testPredicatedLoop() throws Exception(Code) testPredicatedToStayInLoop public void testPredicatedToStayInLoop() throws Exception(Code) testPredsButSyntaxResolves public void testPredsButSyntaxResolves() throws Exception(Code) testPredsUsedAfterRecursionOverflow public void testPredsUsedAfterRecursionOverflow() throws Exception(Code) testTooFewSemanticPredicates public void testTooFewSemanticPredicates() throws Exception(Code) testUniquePredicateOR public void testUniquePredicateOR() throws Exception(Code) For a DFA state with lots of configurations that have the same predicate, don't just OR them all together as it's a waste to test a||a||b||a||a etc...
