将用于 IEEE 1722 AVTPDU 流的常见头字段（如时间戳和序列号）封装为可选值。

类 ara::rds::IEEE1722DatagramAVTPDUCommonStreamHeaderFields 在模块 rds 中用作受保护的基础结构，以封装用于 IEEE 1722 AVTPDU 数据报的公共流头字段 SWS RawDataStream 第1页。它在 ara::core::Optional 字段中保存与协议相关的属性（如序列号和时间戳），这些字段通常通过派生的数据报类进行实例化和求值。通过声明为 noexcept 的虚析构函数来确保实例的安全多态销毁 [SWS_RDS_90242]。在读取访问这些属性之前，必须始终检查相应 Optional 值的有效性。

上下文

类 ara::rds::IEEE1722DatagramAVTPDUCommonStreamHeaderFields 在 AUTOSAR Adaptive Platform 的 Raw Data Stream 模块 (rds) 内提供针对 IEEE 1722 AVTPDU 数据报的流头字段的公共表示 SWS RawDataStream 第1页。它通过头文件 #include "ara/rds/raw_data_stream_IEEE1722.h" 包含，并构成通过基于以太网的数据流处理音频/视频传输协议数据单元 (AVTPDU) 的标准化基础。规范中定义的所有协议变量均带有访问修饰符 protected（[SWS_RDS_90235]、[SWS_RDS_90236]、[SWS_RDS_90237]、[SWS_RDS_90238]、[SWS_RDS_90239]、[SWS_RDS_90240]、[SWS_RDS_90241]）。Interpretation: 这表明该类被设计为专用数据报类型的继承基类，可能并不适合在应用程序代码中作为独立对象直接使用。问题 Q-11a6ac64bcd3c7d8 (未决)

该类汇集了 IEEE 1722 AVTP 流的协议属性。其中包括用于跟踪数据包顺序的序列号 sequenceNum [SWS_RDS_90240]、用于同步网络中时间归类的类型为 ara::tsync::Timestamp 的时间戳 avtp_timestamp [SWS_RDS_90237]，以及时间不确定性标志 tu [SWS_RDS_90241]。诸如 MAC 地址、标识符和标志等附加头字段完善了协议帧（[SWS_RDS_90235]、[SWS_RDS_90236]、[SWS_RDS_90238]、[SWS_RDS_90239]）。将每个数据字段一致封装到 ara::core::Optional 中，考虑到了根据 AVTPDU 格式变体的不同并非所有字段都必须被占用的情况。

生命周期

公共头字段的实例化和生命周期与相应的派生数据报类直接绑定。由于成员声明为 protected，因此一旦接收到 AVTPDU 流或将其组装以供发送，它们通常就会在专用子类的构造函数中创建 SWS RawDataStream 第1页。

为了正确进行销毁，该类声明了一个带有标识符 ~IEEE1722DatagramAVTPDUCommonStreamHeaderFields() noexcept 的虚析构函数 [SWS_RDS_90242]。通过虚机制可确保通过基类指针删除数据报时，会执行派生类实例的完整析构函数调用。标记为 noexcept 保证了在销毁过程中不会抛出任何异常。

关于并发性，该类未提供同步机制。Interpretation: 在并行处理时对受保护成员的线程安全访问，大概必须由使用层的上层机制来保证。问题 (未决)

使用路径

在实践中，使用通常遵循以下流程：

创建与填充：派生数据报类实例化头结构。发送时，它填充所需的 ara::core::Optional 字段，例如序列号 sequenceNum [SWS_RDS_90240] 和 AVTP 时间戳 avtp_timestamp [SWS_RDS_90237]。
接收路径中的处理：传入的原始数据被反序列化并分配给属性。求值逻辑检查可选值的存在性，并例如通过同步时间戳 [SWS_RDS_90237] 处理时序，或根据 sequenceNum [SWS_RDS_90240] 丢弃重复的数据包。
释放：处理流之后，通过析构函数清理实例 [SWS_RDS_90242]。

错误场景

规范中未为该类定义特定的错误代码或异常类型。可能的错误状态仅限于可选数据字段的处理和接口条件：

由于所有字段均封装为 ara::core::Optional（[SWS_RDS_90235]、[SWS_RDS_90236]、[SWS_RDS_90237]、[SWS_RDS_90238]、[SWS_RDS_90239]、[SWS_RDS_90240]、[SWS_RDS_90241]），因此在访问其值之前必须确保该字段已有效填充。对空的 Optional 对象的未检查直接访问会导致错误行为。

析构函数声明为 noexcept [SWS_RDS_90242]。因此，在派生结构中进行资源清理时可能发生的任何错误都不得作为异常传递，而必须在内部进行处理。

本指南基于 AUTOSAR Adaptive R25-11 规范。
