Doxygen：如何在多个组中包含元素

Question

Doxygen文档说\ ingroup可用于将实体添加到多个组：

\ingroup (<groupname> [<groupname> <groupname>])

问题是我尝试了它并且Doxygen将实体添加到组列表中的最后一个组。就像是

/** \ingroup A B
 * ...
 */

将元素添加到模块A，但不添加到B.有谁知道原因，以及如何解决它？

我尝试使用Doxygen版本1.7.6.1和1.8.1.2。

谢谢你的帮助。

编辑：我意识到doxygen输出一个警告说：

Member X found in multiple @ingroup groups! The member will be put in group B, and not in group A

在我看来，这与文档相矛盾。

答案：我自己回答。我试图将函数添加到多个组，但文档说“注意复合实体（如类，文件和命名空间）可以放在多个组中，但成员（如变量，函数，typedef和枚举）只能是一个一组成员“。

您通常（对于允许的项目，比方说文件）只需要编写具有多个组的内组。为了完整起见，让我展示一下我使用的模板：

/**
 * \file
 * \ingroup GrpTest GrpLicense
 * \brief Here your brief explanation
 * \details And you put here a more detailed explanation to the 
 * contents of the file.
 * \version 1.0
 * \date 2014-09-27

现在，从Doxygen Documentation，特别是这里链接的页面，你读到：

Note that compound entities (like classes, files and namespaces) 
can be put into multiple groups, 
but members (like variable, functions, typedefs and enums) 
can only be a member of one group 

该文档还解释了原因：

(this restriction is in place to avoid ambiguous linking
targets in case a member is not documented in the context
of its class, namespace or file, but only visible as part of a group).

因此，简而言之，遗憾的是，您无法将多个组添加一个函数（或各种实体，就像您未指定的那样）。

我希望这个链接可以帮助您解决更多问题。

用于

/** \ingroup A B
 * ...
 */

只有在其他地方定义时才会将项目添加到组A和B。如果未定义组，则不会仅仅因为它在\ingroup命令中使用而定义。

你应该能够通过使用获得组B中的项目

/** \defgroup B
 * @{
 * @}
 */
/** \ingroup A B
 * ...
 */
