Examples of PredicateTransition

org.antlr.v4.runtime.atn.PredicateTransition
TODO: this is old comment: A tree of semantic predicates from the grammar AST if label==SEMPRED. In the ATN, labels will always be exactly one predicate, but the DFA may have to combine a bunch of them as it collects predicates from multiple ATN configurations into a single DFA state.

Examples of org.antlr.v4.runtime.atn.PredicateTransition

      int precedence = Integer.parseInt(pred.getOptionString(LeftRecursiveRuleTransformer.PRECEDENCE_OPTION_NAME));
      p = new PrecedencePredicateTransition(right, precedence);
    }
    else {
      boolean isCtxDependent = UseDefAnalyzer.actionIsContextDependent(pred);
      p = new PredicateTransition(right, currentRule.index, g.sempreds.get(pred), isCtxDependent);
    }


    left.addTransition(p);
    pred.atnState = left;
    return new Handle(left, right);
