描述符对象

“描述符”是描述对象的某些属性的对象。它们存在于类型对象的字典中。

PyTypeObject PyProperty_Type

Part of the Stable ABI.

内建描述符类型的类型对象。

PyObject *PyDescr_NewGetSet(PyTypeObject *type, struct PyGetSetDef *getset)

Return value: New reference. Part of the Stable ABI.

PyObject *PyDescr_NewMember(PyTypeObject *type, struct PyMemberDef *meth)

Return value: New reference. Part of the Stable ABI.

PyObject *PyDescr_NewMethod(PyTypeObject *type, struct PyMethodDef *meth)

Return value: New reference. Part of the Stable ABI.

PyObject *PyDescr_NewWrapper(PyTypeObject *type, struct wrapperbase *wrapper, void *wrapped)

Return value: New reference.

PyObject *PyDescr_NewClassMethod(PyTypeObject *type, PyMethodDef *method)

Return value: New reference. Part of the Stable ABI.

int PyDescr_IsData(PyObject *descr)

如果描述符对象 descr 描述的是一个数据属性则返回非零值，或者如果它描述的是一个方法则返回 0。 descr 必须为一个描述符对象；不会进行错误检测。
