- 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.TypeTypein the Python layer.
int PyType_Check( PyObject *o) - Returns true if the object o is a type object, including instances of types derived from the standard type object. Returns false in all other cases.
int PyType_CheckExact( PyObject *o) - Returns true if the object o is a type object, but not a subtype of the standard type object. Returns false in all other cases. New in version 2.2.
int PyType_HasFeature( PyObject *o, int feature) - Returns 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) - Returns 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. Returns
0on success, or returns-1and sets an exception on error. New in version 2.2.
