Generator Objects
|
|
-----------------
|
|
|
|
Generator objects are what Python uses to implement generator iterators. They
|
|
are normally created by iterating over a function that yields values, rather
|
|
than explicitly calling :c:func:`PyGen_New` or :c:func:`PyGen_NewWithQualName`.
|
|
|
|
|
|
.. c:type:: PyGenObject
|
|
|
|
The C structure used for generator objects.
|
|
|
|
|
|
.. c:var:: PyTypeObject PyGen_Type
|
|
|
|
The type object corresponding to generator objects.
|
|
|
|
|
|
.. c:function:: int PyGen_Check(PyObject *ob)
|
|
|
|
Return true if *ob* is a generator object; *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: int PyGen_CheckExact(PyObject *ob)
|
|
|
|
Return true if *ob*'s type is *PyGen_Type*; *ob* must not be *NULL*.
|
|
|
|
|
|
.. c:function:: PyObject* PyGen_New(PyFrameObject *frame)
|
|
|
|
Create and return a new generator object based on the *frame* object.
|
|
A reference to *frame* is stolen by this function. The argument must not be
|
|
*NULL*.
|
|
|
|
.. c:function:: PyObject* PyGen_NewWithQualName(PyFrameObject *frame, PyObject *name, PyObject *qualname)
|
|
|
|
Create and return a new generator object based on the *frame* object,
|
|
with ``__name__`` and ``__qualname__`` set to *name* and *qualname*.
|
|
A reference to *frame* is stolen by this function. The *frame* argument
|
|
must not be *NULL*.
