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。

PyTypeObjectPyProperty_Type
穩定 ABI 的一部分.

內建 descriptor 型別的型別物件。

PyObject*PyDescr_NewGetSet(PyTypeObject*type,structPyGetSetDef*getset)
回傳值:新的參照。穩定 ABI 的一部分.
PyObject*PyDescr_NewMember(PyTypeObject*type,structPyMemberDef*meth)
回傳值:新的參照。穩定 ABI 的一部分.
PyTypeObjectPyMemberDescr_Type
穩定 ABI 的一部分.

The type object for member descriptor objects created fromPyMemberDef structures. These descriptors expose fields of aC struct as attributes on a type, and correspondtotypes.MemberDescriptorType objects in Python.

PyTypeObjectPyGetSetDescr_Type
穩定 ABI 的一部分.

The type object for get/set descriptor objects created fromPyGetSetDef structures. These descriptors implement attributeswhose value is computed by C getter and setter functions, and are usedfor many built-in type attributes.

PyObject*PyDescr_NewMethod(PyTypeObject*type,structPyMethodDef*meth)
回傳值:新的參照。穩定 ABI 的一部分.
PyTypeObjectPyMethodDescr_Type
穩定 ABI 的一部分.

The type object for method descriptor objects created fromPyMethodDef structures. These descriptors expose C functions asmethods on a type, and correspond totypes.MemberDescriptorTypeobjects in Python.

PyObject*PyDescr_NewWrapper(PyTypeObject*type,structwrapperbase*wrapper,void*wrapped)
回傳值:新的參照。
PyTypeObjectPyWrapperDescr_Type
穩定 ABI 的一部分.

The type object for wrapper descriptor objects created byPyDescr_NewWrapper() andPyWrapper_New(). Wrapperdescriptors are used internally to expose special methods implementedvia wrapper structures, and appear in Python astypes.WrapperDescriptorType objects.

PyObject*PyDescr_NewClassMethod(PyTypeObject*type,PyMethodDef*method)
回傳值:新的參照。穩定 ABI 的一部分.
intPyDescr_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.

內建描述器

PyTypeObjectPySuper_Type
穩定 ABI 的一部分.

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

PyTypeObjectPyClassMethod_Type

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

PyTypeObjectPyClassMethodDescr_Type
穩定 ABI 的一部分.

The type object for C-level class method descriptor objects.This is the type of the descriptors created forclassmethod() defined inC extension types, and is the same object asclassmethodin Python.

PyObject*PyClassMethod_New(PyObject*callable)

Create a newclassmethod object wrappingcallable.callable must be a callable object and must not beNULL.

On success, this function returns astrong reference to a new classmethod descriptor. On failure, this function returnsNULL with anexception set.

PyTypeObjectPyStaticMethod_Type

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

PyObject*PyStaticMethod_New(PyObject*callable)

Create a newstaticmethod object wrappingcallable.callable must be a callable object and must not beNULL.

On success, this function returns astrong reference to a new staticmethod descriptor. On failure, this function returnsNULL with anexception set.
