Descriptor Objects

“Descriptors” are objects that describe some attribute of an object. They arefound in the dictionary of type objects.

PyTypeObjectPyProperty_Type
Part of theStable ABI.

The type object for the built-in descriptor types.

PyObject*PyDescr_NewGetSet(PyTypeObject*type,structPyGetSetDef*getset)
Return value: New reference. Part of theStable ABI.
PyObject*PyDescr_NewMember(PyTypeObject*type,structPyMemberDef*meth)
Return value: New reference. Part of theStable ABI.
PyObject*PyDescr_NewMethod(PyTypeObject*type,structPyMethodDef*meth)
Return value: New reference. Part of theStable ABI.
PyObject*PyDescr_NewWrapper(PyTypeObject*type,structwrapperbase*wrapper,void*wrapped)
Return value: New reference.
PyObject*PyDescr_NewClassMethod(PyTypeObject*type,PyMethodDef*method)
Return value: New reference. Part of theStable ABI.
intPyDescr_IsData(PyObject*descr)

Return non-zero if the descriptor objectdescr describes a data attribute, or0 if it describes a method.descr must be a descriptor object; there isno error checking.

PyObject*PyWrapper_New(PyObject*,PyObject*)
Return value: New reference. Part of theStable ABI.

Built-in descriptors

PyTypeObjectPySuper_Type
Part of theStable ABI.

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.

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.
