Descriptor(描述器)物件

"Descriptor" 是描述物件某些屬性的物件,它們存在於型別物件的 dictionary(字典)中。

PyTypeObject PyProperty_Type
穩定 ABI 的一部分.

內建 descriptor 型別的型別物件。

PyObject *PyDescr_NewGetSet(PyTypeObject *type, struct PyGetSetDef *getset)
回傳值:新的參照。穩定 ABI 的一部分.
PyObject *PyDescr_NewMember(PyTypeObject *type, struct PyMemberDef *meth)
回傳值:新的參照。穩定 ABI 的一部分.
PyObject *PyDescr_NewMethod(PyTypeObject *type, struct PyMethodDef *meth)
回傳值:新的參照。穩定 ABI 的一部分.
PyObject *PyDescr_NewWrapper(PyTypeObject *type, struct wrapperbase *wrapper, void *wrapped)
回傳值:新的參照。
PyObject *PyDescr_NewClassMethod(PyTypeObject *type, PyMethodDef *method)
回傳值:新的參照。穩定 ABI 的一部分.
int PyDescr_IsData(PyObject *descr)

如果 descriptor 物件 descr 描述的是一個資料屬性則回傳非零值,或者如果它描述的是一個方法則回傳 0descr 必須為一個 descriptor 物件;沒有錯誤檢查。

PyObject *PyWrapper_New(PyObject*, PyObject*)
回傳值:新的參照。穩定 ABI 的一部分.

Built-in descriptors

PyTypeObject PySuper_Type
穩定 ABI 的一部分.

The type object for super objects. This is the same object as super in the Python layer.

PyTypeObject PyClassMethod_Type

The type of class method objects. This is the same object as classmethod in the Python layer.

PyObject *PyClassMethod_New(PyObject *callable)

Create a new classmethod object wrapping callable. callable must be a callable object and must not be NULL.

On success, this function returns a strong reference to a new class method descriptor. On failure, this function returns NULL with an exception set.

PyTypeObject PyStaticMethod_Type

The type of static method objects. This is the same object as staticmethod in the Python layer.

PyObject *PyStaticMethod_New(PyObject *callable)

Create a new staticmethod object wrapping callable. callable must be a callable object and must not be NULL.

On success, this function returns a strong reference to a new static method descriptor. On failure, this function returns NULL with an exception set.
