grouping - Doxygen:如何在多个组中包含一个元素

Question

Doxygen 文档说\ingroup 可用于将实体添加到多个组:

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

问题是我试过了，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。有谁知道为什么，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:我自己回答。我试图将函数添加到多个组，但文档说“请注意，复合实体(如类、文件和命名空间)可以放入多个组中，但成员(如变量、函数、typedef 和枚举)只能是一个团体的成员”。

您通常(对于允许的项目，比如说一个文件)只需要编写一个带有多个组的内组。为了完整起见，让我展示一个我使用的模板:

/**
 * \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，来自 Doxygen Documentation ，特别是此处链接的页面，您阅读:

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，不幸的是，您无法将函数(或您未指定的所有类型的实体)添加到多个组中。

我希望此链接可以帮助您解决更多问题。
