c++ - Doxygen 是否支持分支或 C/C++ 预处理器

Question

这听起来像是一个科幻功能请求，但我想知道 Doxygen 是否具有以下两个功能中的任何一个:

1. 在预处理器运行输入文件后生成调用/调用者图。示例:
   

   #define MULTITHREADING 1
   

   然后根据是否启用 MULTITHREADING 启用或禁用代码块。

2. 用图形箭头描述调用的确定性...例如，如果函数并不总是被调用(也就是它在分支中或者您有可能 return 在函数被调用之前。

Answer 1

1. 氧气 Preprocessing :

   Source files that are used as input to doxygen can be parsed by doxygen's built-in C-preprocessor.

   By default doxygen does only partial preprocessing. That is, it evaluates conditional compilation statements (like #if) and evaluates macro definitions, but it does not perform macro expansion.

2. COLLABORATION_GRAPH :

   If the COLLABORATION_GRAPH and HAVE_DOT tags are set to YES then doxygen will generate a graph for each documented class showing the direct and indirect implementation dependencies (inheritance, containment, and class references variables) of the class with other documented classes.
