Examples of org.antlr.runtime.FailedPredicateException

org.antlr.runtime.FailedPredicateException
A semantic predicate failed during validation. Validation of predicates occurs when normally parsing the alternative just like matching a token. Disambiguating predicate evaluation occurs when we hoist a predicate into a prediction decision.

      } else if (e instanceof MismatchedTokenException) {
        MismatchedTokenException mte = (MismatchedTokenException) e;

      } else if (e instanceof FailedPredicateException) {
        FailedPredicateException fpe = (FailedPredicateException) e;
        msg = "Failed to recognize predicate '" + fpe.token.getText() + "'. Failed rule: '" + fpe.ruleName + "'";
      } else {
        msg = super.getErrorMessage(e, xlateNames);
