How to parse DynamicData get by Subscriber?

[ulongcha]

        eprosima::fastrtps::types::DynamicData_ptr data = dit->second;
        SampleInfo info;
        if (reader->take_next_sample(data.get(), &info) == ReturnCode_t::RETCODE_OK)
        {
            if (info.instance_state == ALIVE_INSTANCE_STATE)
            {
                eprosima::fastrtps::types::DynamicType_ptr type = subscriber_->readers_[reader];
                this->n_samples++;
                std::cout << "Received data of type " << type->get_name() << std::endl;
                // eprosima::fastrtps::types::DynamicDataHelper::print(data);
            }
        }

Through DataReader Dynamic Topic type and DynamicData can be derived. Use eprosima::fastrtps::types::DynamicDataHelper can print data. In the soure code of eprosima::fastrtps::types::DynamicDataHelper is easily to parse the DynamicData since its a friend class of class eprosima::fastrtps::types::DynamicData. How to parse the DynamicData by myself without friend class?
