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 PyGen_New() or PyGen_NewWithQualName().

PyGenObject

The C structure used for generator objects.

PyTypeObject PyGen_Type

The type object corresponding to generator objects.

int PyGen_Check(PyObject *ob)

Return true if ob is a generator object; ob must not be NULL.

int PyGen_CheckExact(PyObject *ob)

Return true if ob’s type is PyGen_Type; ob must not be NULL.

PyObject* PyGen_New(PyFrameObject *frame)

Return value: New reference.

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.

PyObject* PyGen_NewWithQualName(PyFrameObject *frame, PyObject *name, PyObject *qualname)

Return value: New reference.

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.
