Examples of loop.ast.script.ArgDeclList

loop.ast.script.ArgDeclList
Represents a declaration of arguments of a function.


    Node third = list.children().get(2);
    if (!(third instanceof InlineListDef))
      throw new RuntimeException("Expected argument definition");


    ArgDeclList args = new ArgDeclList();
    List<Node> exprs = reduce(third).children();
    for (Node expr : exprs) {
      Variable argName = (Variable) expr;
      args.add(new ArgDeclList.Argument(argName.name, null));
    }


    FunctionDecl functionDecl = new FunctionDecl(name, args);


    Node fourth = list.children().get(3);
