        if (list)

            if (s)
            {
              TemplateVariant value = s->get(args.toString());
              //printf("value type=%s\n",value.typeAsString());
              if (value.toBool())
              {
                //printf("keeping it\n");
                result->append(item);
              }
              else
              {
                //printf("Dropping it\n");
              }
            }
          }
          return TemplateVariant(std::static_pointer_cast<TemplateListIntf>(result));
        }
      }
      return v;
    }

引用了 TemplateList::alloc(), TemplateVariant::isList(), TemplateVariant::isString(), TemplateVariant::isValid(), TemplateVariant::toBool(), TemplateVariant::toList(), TemplateVariant::toString() , 以及 TemplateVariant::toStruct().
