unable to catch warning in error listener

[Peter Cheung]

Hi

   I have this "warning(125): :32:5: implicit definition of token MISSING_STATEMENT in parser". But i can't catch warning in my error listener:

public class MyBaseErrorListener extends BaseErrorListener {

public boolean compilerError = false;

@Override

public void syntaxError(final Recognizer<?, ?> recognizer, final Object offendingSymbol, final int line, final int position, final String msg, final RecognitionException e) {

compilerError = true;

ModuleLib.log("ERROR :" + line + ":" + position + ": " + msg);

}

public void reportAmbiguity(Parser recognizer, DFA dfa, int startIndex, int stopIndex, boolean exact, BitSet ambigAlts, ATNConfigSet configs) {

ModuleLib.log("reportAmbiguity");

}

public void reportAttemptingFullContext(Parser recognizer, DFA dfa, int startIndex, int stopIndex, BitSet conflictingAlts, ATNConfigSet configs) {

ModuleLib.log("reportAttemptingFullContext");

}

public void reportContextSensitivity(Parser recognizer, DFA dfa, int startIndex, int stopIndex, int prediction, ATNConfigSet configs) {

ModuleLib.log("reportContextSensitivity");

}

}

Tool tool = new Tool();

Grammar grammar = tool.createGrammar(ast);

tool.process(grammar, false);

MyBaseErrorListener errorListener = new MyBaseErrorListener();

CommonTokenStream tokenStream = new CommonTokenStream(lexer);

ParserInterpreter parser = grammar.createParserInterpreter(tokenStream);

parser.getInterpreter().setPredictionMode(PredictionMode.LL);

parser.removeErrorListeners();

parser.addErrorListener(errorListener);

String startRule = "assemble";

Rule start = grammar.getRule(startRule);

ParserRuleContext parserRuleContext = parser.parse(start.index);

thanks

No wonder, this warning is issued by ANTLR when generating the files from the grammar, not your parser.
