.. method:: BaseEventLoop.set_task_factory(factory)

Set a task factory that will be used by

:meth:`BaseEventLoop.create_task`.

If *factory* is ``None`` the default task factory will be set.

If *factory* is a *callable*, it should have a signature matching

``(loop, coro)``, where *loop* will be a reference to the active

event loop, *coro* will be a coroutine object. The callable

must return an :class:`asyncio.Future` compatible object.
