C++域

The C++ domain (name cpp) supports documenting C++ projects.

The following directives are available:

.. cpp:class:: signatures

.. cpp:function:: signatures

.. cpp:member:: signatures

.. cpp:type:: signatures

Describe a C++ object. Full signature specification is supported – give the signature as you would in the declaration. Here some examples:

.. cpp:function:: bool namespaced::theclass::method(int arg1, std::string arg2)

   Describes a method with parameters and types.

.. cpp:function:: bool namespaced::theclass::method(arg1, arg2)

   Describes a method without types.

.. cpp:function:: const T &array<T>::operator[]() const

   Describes the constant indexing operator of a templated array.

.. cpp:function:: operator bool() const

   Describe a casting operator here.

.. cpp:function:: constexpr void foo(std::string &bar[2]) noexcept

   Describe a constexpr function here.

.. cpp:member:: std::string theclass::name

.. cpp:member:: std::string theclass::name[N][M]

.. cpp:type:: theclass::const_iterator

Will be rendered like this:

bool namespaced::theclass::method(int arg1, std::string arg2)

Describes a method with parameters and types.

bool namespaced::theclass::method(arg1, arg2)

Describes a method without types.

template<>
const T &array<T>::operator[]() const

Describes the constant indexing operator of a templated array.

operator bool() const

Describe a casting operator here.

constexpr void foo(std::string &bar[2]) noexcept

Describe a constexpr function here.

std::string theclass::name

std::string theclass::name[N][M]

type theclass::const_iterator

.. cpp:namespace:: namespace

Select the current C++ namespace for the following objects.

These roles link to the given object types:

:cpp:class:

:cpp:func:

:cpp:member:

:cpp:type:

Reference a C++ object. You can give the full signature (and need to, for overloaded functions.)

注解

Sphinx’ syntax to give references a custom title can interfere with linking to template classes, if nothing follows the closing angle bracket, i.e. if the link looks like this: :cpp:class:`MyClass<T>`. This is interpreted as a link to T with a title of MyClass. In this case, please escape the opening angle bracket with a backslash, like this: :cpp:class:`MyClass\<T>`.

Note on References

It is currently impossible to link to a specific version of an overloaded method. Currently the C++ domain is the first domain that has basic support for overloaded methods and until there is more data for comparison we don’t want to select a bad syntax to reference a specific overload. Currently Sphinx will link to the first overloaded version of the method / function.
