tornado.platform.twisted --- Bridges between Twisted and Tornado

.. module:: tornado.platform.twisted

.. deprecated:: 6.0

This module is no longer recommended for new code. Instead of using direct integration between Tornado and Twisted, new applications should rely on the integration with asyncio provided by both packages.

Importing this module has the side effect of registering Twisted's Deferred class with Tornado's @gen.coroutine so that Deferred objects can be used with yield in coroutines using this decorator (importing this module has no effect on native coroutines using async def).

.. function:: install()

Install ``AsyncioSelectorReactor`` as the default Twisted reactor.

.. deprecated:: 5.1

   This function is provided for backwards compatibility; code
   that does not require compatibility with older versions of
   Tornado should use
   ``twisted.internet.asyncioreactor.install()`` directly.

.. versionchanged:: 6.0.3

   In Tornado 5.x and before, this function installed a reactor
   based on the Tornado ``IOLoop``. When that reactor
   implementation was removed in Tornado 6.0.0, this function was
   removed as well. It was restored in Tornado 6.0.3 using the
   ``asyncio`` reactor instead.
