7.1.1 Type Objects
- PyTypeObject
-
The C structure of the objects used to describe built-in types.
- PyObject* PyType_Type
-
This is the type object for type objects; it is the same object as
types.TypeType in the Python layer.
| int PyType_Check( | PyObject *o) |
-
Return true if the object o is a type object, including
instances of types derived from the standard type object. Return
false in all other cases.
| int PyType_CheckExact( | PyObject *o) |
-
Return true if the object o is a type object, but not a
subtype of the standard type object. Return false in all other
cases.
New in version 2.2.
| int PyType_HasFeature( | PyObject *o, int feature) |
-
Return true if the type object o sets the feature
feature. Type features are denoted by single bit flags.
| int PyType_IS_GC( | PyObject *o) |
-
Return true if the type object includes support for the cycle
detector; this tests the type flag Py_TPFLAGS_HAVE_GC.
New in version 2.0.
| int PyType_IsSubtype( | PyTypeObject *a, PyTypeObject *b) |
-
Return true if a is a subtype of b.
New in version 2.2.
| PyObject* PyType_GenericAlloc( | PyTypeObject *type,
int nitems) |
-
Return value:
New reference.
New in version 2.2.
| PyObject* PyType_GenericNew( | PyTypeObject *type,
PyObject *args, PyObject *kwds) |
-
Return value:
New reference.
New in version 2.2.
| int PyType_Ready( | PyTypeObject *type) |
-
Finalize a type object. This should be called on all type objects
to finish their initialization. This function is responsible for
adding inherited slots from a type's base class. Return
0
on success, or return -1 and sets an exception on error.
New in version 2.2.
Release 2.4.5, documentation updated on 18 October 2006.
