Examples of org.antlr.runtime.tree.ParseTree

org.antlr.runtime.tree.ParseTree
A record of the rules used to match a token sequence. The tokens end up as the leaves of this tree and rule nodes are the interior nodes. This really adds no functionality, it is just an alias for CommonTree that is more meaningful (specific) and holds a String to display for a node.

  public void exitRule(String filename, String ruleName) {
    callStack.pop();
  }


  public void consumeToken(Token token) {
    ParseTree ruleNode = (ParseTree)callStack.peek();
    ParseTree elementNode = create(token);
    ruleNode.addChild(elementNode);
  }

    ParseTree elementNode = create(token);
    ruleNode.addChild(elementNode);
  }


  public void recognitionException(RecognitionException e) {
    ParseTree ruleNode = (ParseTree)callStack.peek();
    ParseTree errorNode = create(e);
    ruleNode.addChild(errorNode);
  }
