Descriptor Objects
******************

"Descriptors" are objects that describe some attribute of an object.
They are found in the dictionary of type objects.

PyTypeObject PyProperty_Type
    * Parte del ABI Stabile.*

   The type object for the built-in descriptor types.

PyObject *PyDescr_NewGetSet(PyTypeObject *type, struct PyGetSetDef *getset)
    *Valore di ritorno: Nuovo riferimento.** Parte del ABI Stabile.*

PyObject *PyDescr_NewMember(PyTypeObject *type, struct PyMemberDef *meth)
    *Valore di ritorno: Nuovo riferimento.** Parte del ABI Stabile.*

PyTypeObject PyMemberDescr_Type
    * Parte del ABI Stabile.*

   The type object for member descriptor objects created from
   "PyMemberDef" structures. These descriptors expose fields of a C
   struct as attributes on a type, and correspond to
   "types.MemberDescriptorType" objects in Python.

PyTypeObject PyGetSetDescr_Type
    * Parte del ABI Stabile.*

   The type object for get/set descriptor objects created from
   "PyGetSetDef" structures. These descriptors implement attributes
   whose value is computed by C getter and setter functions, and are
   used for many built-in type attributes.

PyObject *PyDescr_NewMethod(PyTypeObject *type, struct PyMethodDef *meth)
    *Valore di ritorno: Nuovo riferimento.** Parte del ABI Stabile.*

PyTypeObject PyMethodDescr_Type
    * Parte del ABI Stabile.*

   The type object for method descriptor objects created from
   "PyMethodDef" structures. These descriptors expose C functions as
   methods on a type, and correspond to "types.MemberDescriptorType"
   objects in Python.

PyObject *PyDescr_NewWrapper(PyTypeObject *type, struct wrapperbase *wrapper, void *wrapped)
    *Valore di ritorno: Nuovo riferimento.*

PyTypeObject PyWrapperDescr_Type
    * Parte del ABI Stabile.*

   The type object for wrapper descriptor objects created by
   "PyDescr_NewWrapper()" and "PyWrapper_New()". Wrapper descriptors
   are used internally to expose special methods implemented via
   wrapper structures, and appear in Python as
   "types.WrapperDescriptorType" objects.

PyObject *PyDescr_NewClassMethod(PyTypeObject *type, PyMethodDef *method)
    *Valore di ritorno: Nuovo riferimento.** Parte del ABI Stabile.*

int PyDescr_IsData(PyObject *descr)

   Return non-zero if the descriptor object *descr* describes a data
   attribute, or "0" if it describes a method.  *descr* must be a
   descriptor object; there is no error checking.

PyObject *PyWrapper_New(PyObject*, PyObject*)
    *Valore di ritorno: Nuovo riferimento.** Parte del ABI Stabile.*


Built-in descriptors
====================

PyTypeObject PySuper_Type
    * Parte del ABI Stabile.*

   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.

PyTypeObject PyClassMethodDescr_Type
    * Parte del ABI Stabile.*

   The type object for C-level class method descriptor objects. This
   is the type of the descriptors created for "classmethod()" defined
   in C extension types, and is the same object as "classmethod" in
   Python.

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.
