實體方法物件¶
An instance method is a wrapper for a PyCFunction
and the new way
to bind a PyCFunction
to a class object. It replaces the former call
PyMethod_New(func, NULL, class)
.
-
PyTypeObject
PyInstanceMethod_Type
¶ This instance of
PyTypeObject
represents the Python instance method type. It is not exposed to Python programs.
-
int
PyInstanceMethod_Check
(PyObject *o)¶ Return true if o is an instance method object (has type
PyInstanceMethod_Type
). The parameter must not beNULL
.
-
PyObject*
PyInstanceMethod_New
(PyObject *func)¶ - Return value: New reference.
Return a new instance method object, with func being any callable object func is the function that will be called when the instance method is called.
-
PyObject*
PyInstanceMethod_Function
(PyObject *im)¶ - Return value: Borrowed reference.
Return the function object associated with the instance method im.
-
PyObject*
PyInstanceMethod_GET_FUNCTION
(PyObject *im)¶ - Return value: Borrowed reference.
Macro version of
PyInstanceMethod_Function()
which avoids error checking.
Method Objects¶
Methods are bound function objects. Methods are always bound to an instance of a user-defined class. Unbound methods (methods bound to a class object) are no longer available.

PyTypeObject
PyMethod_Type
¶ This instance of
PyTypeObject
represents the Python method type. This is exposed to Python programs astypes.MethodType
.
-
int
PyMethod_Check
(PyObject *o)¶ Return true if o is a method object (has type
PyMethod_Type
). The parameter must not beNULL
.
-
PyObject*
PyMethod_New
(PyObject *func, PyObject *self)¶ - Return value: New reference.
Return a new method object, with func being any callable object and self the instance the method should be bound. func is the function that will be called when the method is called. self must not be
NULL
.
-
PyObject*
PyMethod_Function
(PyObject *meth)¶ - Return value: Borrowed reference.
Return the function object associated with the method meth.
-
PyObject*
PyMethod_GET_FUNCTION
(PyObject *meth)¶ - Return value: Borrowed reference.
Macro version of
PyMethod_Function()
which avoids error checking.
-
PyObject*
PyMethod_Self
(PyObject *meth)¶ - Return value: Borrowed reference.
Return the instance associated with the method meth.
-
PyObject*
PyMethod_GET_SELF
(PyObject *meth)¶ - Return value: Borrowed reference.
Macro version of
PyMethod_Self()
which avoids error checking.
-
int
PyMethod_ClearFreeList
()¶ Clear the free list. Return the total number of freed items.
