c++ - Doxygen 警告 : no uniquely matching class member found for

Question

我将 Doxygen 用于 C++ 项目。在构建 html 文档时，出现以下错误:

C:/Amir/Programming/Eclipse C++/CacheOptimization/src/CacheLruNaiveAlgorithm.cpp:19:

warning: no uniquely matching class member found for

void CacheOpt::CacheLruNaiveAlgorithm::init(TierList &tierList, TierMap *tierMap)

此警告的来源可能是什么？一般是什么原因造成的？

编辑:

这是一个 doxygen 提示的示例方法定义/声明(我删除了一些东西，比如参数类型，因为它受 IP 保护。在任何地方都没有使用宏):

算法.h

namespace CacheOpt {
    class Algorithm {
        protected:
            /*..*/
        public:
            virtual void init(/*..*/);
            virtual std::string getName() = 0;
    };
} //CacheOpt

算法.cpp

#include "Algorithm.h"

void
CacheOpt::Algorithm::init(/*..*/) {
    /*..*/
}

我在这里收到此错误:

C:/Amir/Programming/Eclipse C++/CacheOptimization/src/Algorithm.cpp:11: warning: no uniquely matching class member found forvoid CacheOpt::Algorithm::init(/*..*/)

它甚至没有将 Algorithm 识别为一个类!我能做什么？

Answer 1

可能的原因:

• 如果您尝试使用 \function 和 \class 等标签将注释与代码远程关联，请停止。将文档注释直接放在有问题的代码之前会自动关联起来，让代码维护者在修改代码时更有可能更新注释，完全免除了在注释中更新函数签名的负担。

• 具有类外实现的类成员在声明和定义的签名之间存在源代码不匹配。根据 C++ 标准，诸如顶级 const 之类的东西不会改变签名，但 doxygen 在源代码上工作，并尝试使用来自编译器的不同规则来匹配事物。 Typedef 和宏也可能起作用，其中编译器看到与声明相对应的定义，而 doxygen 看到两个单独的函数。可以通过告诉 doxygen 扩展某些宏来解决这个问题，或者可能需要调整声明以完全匹配定义。

• 将作用域运算符与命名空间一起使用或在同名中多次使用。 doxygen 的一些代码假定作用域运算符与类型而不是命名空间一起使用。改用命名空间 block 是一种合理的解决方法。我还看到了多次使用范围解析运算符的问题，doxygen 在继续处理下一个代码片段时可能会保留太多范围。让你的代码更简单，doxygen 会更喜欢它。

对于您的代码示例，这可能会更好:

#include "Algorithm.h"

namespace CacheOpt
{
    void Algorithm::init(/*..*/)
    {
        /*..*/
    }
}

如果这是一种解决方法，请随意使用它，但也可以使用 file a bug report在 the doxygen bug tracker .
