用于在 SOVD 记录内顺序遍历和读取诊断数据元素。

类 ara::diag::DiagnosticSovdRecordContentElementDataIterator 用作顺序遍历 SOVD 记录的诊断数据元素的迭代器([SWS_DM_02258])。通过解引用运算符,应用程序可以获得对 DiagnosticSovdContentElementDataWithKey 类型元素的访问权限,而向前移动则通过递增运算符完成。作为关键约束条件,所有函数均被指定为 noexcept 且线程安全([SWS_DM_02263])。解读:调用方应用程序必须在每次访问前自行检查是否已到达序列末尾,以防止出现未定义行为。 问题 Q-819b2e03155473ad (未决)

上下文

类 ara::diag::DiagnosticSovdRecordContentElementDataIterator 在 AUTOSAR Adaptive Platform 中被指定为 SOVD 记录(面向服务的车辆诊断,Service-Oriented Vehicle Diagnostics)数据元素的迭代器([SWS_DM_02258]、AUTOSAR_AP_SWS_Diagnostics §8.60.10 “Class: DiagnosticSovdRecordContentElementDataIterator”)。在诊断子系统中,它充当标准化的访问接口,以逐元素遍历 SOVD 记录的结构化诊断数据。

主要交互对象包括处理记录数据的请求方诊断应用程序,以及诊断模块的底层数据结构。该迭代器通过其解引用运算符选择性地提供对这些数据元素的引用或指针,从而介导对 DiagnosticSovdContentElementDataWithKey 类型单个数据元素的访问([SWS_DM_02259]、[SWS_DM_02260])。

生命周期

迭代器实例通常在对 SOVD 内容执行查询操作时创建。规范在 API 范围内并未为迭代器定义独立的公共构造函数;因此,推测实例主要由上层容器或查询函数提供,并按值复制。 问题 Q-e79bbdff728ef3f2 (未决)该迭代器引用现有有效负载数据,而不获取其所有权。

遍历过程中的生命周期通过向前步进和位置比较进行控制。通过前缀递增运算符 operator++,迭代器前进到后续数据元素([SWS_DM_02263])。有效性以及是否到达序列末尾通过相等和不等运算符 operator==([SWS_DM_02261])及 operator!=([SWS_DM_02262])与哨兵迭代器或尾后迭代器进行比较来确定。

在并发性方面,该类的所有成员函数均被显式指定为线程安全([SWS_DM_02259]、[SWS_DM_02260]、[SWS_DM_02261]、[SWS_DM_02262]、[SWS_DM_02263])。这允许在多线程环境中对独立的迭代器实例进行并发读取访问。

使用路径

评估 SOVD Record 内容时的典型流程遵循传统的 C++ 前向迭代器模式:

  • 终止条件检查:在每次访问之前,应用程序通过 operator!= 将当前位置与尾后迭代器进行比较([SWS_DM_02262])。
  • 元素访问:如果迭代器位于有效元素上,应用程序要么通过 operator* 引用访问 DiagnosticSovdContentElementDataWithKey([SWS_DM_02259]),要么使用元素访问运算符 operator->([SWS_DM_02260])直接寻址数据元素的方法或字段。
  • 前进:使用 operator++ 将迭代器递增至下一个位置([SWS_DM_02263])。

错误场景

迭代器的所有指定操作均声明为异常安全(exception safe)和 noexcept([SWS_DM_02259]、[SWS_DM_02260]、[SWS_DM_02261]、[SWS_DM_02262]、[SWS_DM_02263])。这意味着在正常运行中不会抛出异常,也不会产生需要评估的错误码。

解读:调用 operator*、operator-> 和 operator++ 的基本前置条件是迭代器必须引用有效位置,且不得等于尾后迭代器。 问题 (未决)在 C++ 标准语境下,递增或解引用无效迭代器可能会导致未定义行为。因此,应用程序必须严格通过 operator!= 或 operator== 检查是否到达末尾([SWS_DM_02261]、[SWS_DM_02262])。

本类指南基于 AUTOSAR Adaptive Platform R25-11 规范(diag 模块),并总结了针对 ara::diag::DiagnosticSovdRecordContentElementDataIterator 的各项要求。

用法与语义

类 ara::diag::DiagnosticSovdRecordContentElementDataIterator 的解引用运算符 operator-> 用于对已寻址的数据元素进行同步成员访问([SWS_DM_02260])。该调用返回一个指向当前元素的 DiagnosticSovdContentElementDataWithKey* 类型指针([SWS_DM_02260])。该接口在头文件 ara/diag/diagnostic_sovd_content_element_data.h 中定义([SWS_DM_02260])。

并发性与边界条件

该函数标明为 noexcept,保证异常安全(exception safe),并被指定为线程安全([SWS_DM_02260])。该成员函数不存在特定的错误码。解释:在调用之前,迭代器必须指向有效的数据元素,且不能等于范围末尾,因为解引用无效的迭代器可能会导致未定义行为。 问题 Q-735b580a0b2c8330 (未决)

相互作用

在处理记录内容的上下文中,该迭代器与其他函数一同使用:

  • 它可以通过 DiagnosticSovdRecordContentElementDataView 上的搜索操作(如 Find)获取([SWS_DM_02285])。
  • 循环控制通常通过前缀递增运算符 operator++([SWS_DM_02263])以及与来自 RecordEnd 的尾迭代器进行比对的不等运算符 operator!=([SWS_DM_02262])实现([SWS_DM_02360])。
  • 针对只读上下文提供了 DiagnosticSovdRecordContentElementDataConstIterator,其 operator-> 返回指向 const DiagnosticSovdContentElementDataWithKey 的指针([SWS_DM_02266])。

此使用说明是自动生成的,基于 AUTOSAR 规范。
