Type Objects
|
|
------------
|
|
|
|
.. index:: object: type
|
|
|
|
|
|
.. ctype:: PyTypeObject
|
|
|
|
The C structure of the objects used to describe built-in types.
|
|
|
|
|
|
.. cvar:: PyObject* PyType_Type
|
|
|
|
.. index:: single: TypeType (in module types)
|
|
|
|
This is the type object for type objects; it is the same object as ``type`` and
|
|
``types.TypeType`` in the Python layer.
|
|
|
|
|
|
.. cfunction:: 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.
|
|
|
|
|
|
.. cfunction:: 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.
|
|
|
|
|
|
.. cfunction:: unsigned int PyType_ClearCache()
|
|
|
|
Clear the internal lookup cache. Return the current version tag.
|
|
|
|
|
|
.. cfunction:: void PyType_Modified(PyTypeObject *type)
|
|
|
|
Invalidate the internal lookup cache for the type and all of its
|
|
subtypes. This function must be called after any manual
|
|
modification of the attributes or base classes of the type.
|
|
|
|
|
|
.. cfunction:: 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.
|
|
|
|
|
|
.. cfunction:: int PyType_IS_GC(PyObject *o)
|
|
|
|
Return true if the type object includes support for the cycle detector; this
|
|
tests the type flag :const:`Py_TPFLAGS_HAVE_GC`.
|
|
|
|
|
|
.. cfunction:: int PyType_IsSubtype(PyTypeObject *a, PyTypeObject *b)
|
|
|
|
Return true if *a* is a subtype of *b*.
|
|
|
|
|
|
.. cfunction:: PyObject* PyType_GenericAlloc(PyTypeObject *type, Py_ssize_t nitems)
|
|
|
|
XXX: Document.
|
|
|
|
|
|
.. cfunction:: PyObject* PyType_GenericNew(PyTypeObject *type, PyObject *args, PyObject *kwds)
|
|
|
|
XXX: Document.
|
|
|
|
|
|
.. cfunction:: 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.
