doxygengroup Directive

This directive generates the appropriate output for the contents of a doxygen group. A doxygen group can be declared with specific doxygen markup in the source comments as cover in the doxygen grouping documentation.

It takes the standard project, path, outline and no-link options and additionally the content-only, members, protected-members, private-members, undoc-members and inner options.

content-only

If this flag is specified, then the directive does not output the name of the group or the group description and instead outputs the contents of the group. This can be useful if the groups are only used for organizational purposes and not to provide additional information.

members

If specified, the public members of any classes in the group output will be displayed. Unlike the doxygenclass members option, this does not optionally take a list of member names to display as this will be applied across multiple classes within the group.

protected-members

If specified, the protected members of any classes in the group output will be displayed.

private-members

If specified, the private members of any classes in the group output will be displayed.

undoc-members

If specified, the undocumented members of any classes in the group output will be displayed provided the appropriate members or private-members options are specified as well.

If you would like to always specify some combination of members, protected-members, private-members and undoc-members then you can use the breathe_default_members configuration variable to set it in the conf.py.

inner

If specified, the groups that were defined inside this group, by either defining them inside the scope of another group, or by using the Doxygen ingroup command, are also parsed and loaded.

Basic Example

The plain doxygengroup directive will output the group name and description and any top level publicly visible members of the group.

.. doxygengroup:: mygroup
   :project: group

It produces this output:

group mygroup

This is the first group.

Functions

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

Content-Only Example

The content-only option changes the output to only include the content of the group and not the group name or description. So this:

.. doxygengroup:: mygroup
   :project: group
   :content-only:

Produces this output:

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

注解

As you can see from the output, section headings like ‘Functions’ are missing from the :content-only: display. This is due to an implementation detail. If post an issue on github if you’d like it addressed.

Members Example

The members option changes the output to include the public members of any classes. The output for any class in the group should be the same as if it had be produced by the doxygenclass directive with the members option specified.

.. doxygengroup:: mygroup
   :project: group
   :members:

It produces this output:

group mygroup

This is the first group.

Functions

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

Public Functions

virtual void publicFunction() const = 0

namespaced class function

class PublicClass
#include <group.h>

A protected class.

class UndocumentedPublicClass

Protected Members Example

The protected-members option changes the output to include the protected members of any classes. The output for any class in the group should be the same as if it had be produced by the doxygenclass directive with the protected-members option specified.

.. doxygengroup:: mygroup
   :project: group
   :protected-members:

It produces this output:

group mygroup

This is the first group.

Functions

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

Protected Functions

inline void protectedFunction()

A protected function.

class ProtectedClass
#include <group.h>

A protected class.

class UndocumentedProtectedClass

Private-Members Example

The private-members option changes the output to include the private members of any classes. The output for any class in the group should be the same as if it had be produced by the doxygenclass directive with the private-members option specified.

.. doxygengroup:: mygroup
   :project: group
   :private-members:

Produces this output:

group mygroup

This is the first group.

Functions

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

Private Functions

virtual void privateFunction() const = 0

This is a private function.

class PrivateClass

A private class.

class UndocumentedPrivateClass

Undocumented Members Example

The undoc-members option changes the output to include any undocumentated members from the sections (public, protected, private) that are being displayed for the classes in the group output.

.. doxygengroup:: mygroup
   :project: group
   :private-members:
   :undoc-members:

Produces this output:

group mygroup

This is the first group.

Functions

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

Private Functions

virtual void privateFunction() const = 0

This is a private function.

virtual void undocumentedPrivateFunction() const = 0
class PrivateClass

A private class.

class UndocumentedPrivateClass

注解

Undocumented classes are still not shown in the output due to an implementation issue. Please post an issue on github if you would like this resolved.

Inner Example

The inner option changes the output to include groups that are defined inside other groups.

.. doxygengroup:: mygroup
   :project: group
   :inner:

Produces this output:

group mygroup

This is the first group.

Functions

void groupedFunction()

This function is in MyGroup.

class GroupedClassTest
#include <group.h>

first class inside of namespace

This is an inner group

class InnerGroupClassTest
#include <group.h>

inner class inside of namespace

Outline Example

This displays only the names of the members of the group and not their documentation. The other options determine which members are displayed.

.. doxygengroup:: mygroup
   :project: group
   :members:
   :outline:

It produces this output:

group mygroup

Functions

void groupedFunction()
class GroupedClassTest

Public Functions

virtual void publicFunction() const = 0
class PublicClass
class UndocumentedPublicClass

Failing Example

This intentionally fails:

.. doxygengroup:: madeupgroup
   :project: group

It produces the following warning message:

警告

Cannot find file “madeupgroup” in doxygen xml output for project “group” from directory: ../../examples/specific/group/xml/
