    """
    This class, which employs the :class:`telegram.ext.Dispatcher`, provides a frontend to
    :class:`telegram.Bot` to the programmer, so they can focus on coding the bot. Its purpose is to
    receive the updates from Telegram and to deliver them to said dispatcher. It also runs in a
    separate thread, so the user can interact with the bot, for example on the command line. The
    dispatcher supports handlers for different kinds of data: Updates from Telegram, basic text
    commands and even arbitrary types. The updater can be started as a polling service or, for
    production, use a webhook to receive updates. This is achieved using the WebhookServer and
    WebhookHandler classes.


    Attributes:
        bot (:class:`telegram.Bot`): The bot used with this Updater.
        user_sig_handler (:obj:`signal`): signals the updater will respond to.
        update_queue (:obj:`Queue`): Queue for the updates.
        job_queue (:class:`telegram.ext.JobQueue`): Jobqueue for the updater.
        dispatcher (:class:`telegram.ext.Dispatcher`): Dispatcher that handles the updates and
            dispatches them to the handlers.
        running (:obj:`bool`): Indicates if the updater is running.

    Args:
        token (:obj:`str`, optional): The bot's token given by the @BotFather.
        base_url (:obj:`str`, optional): Base_url for the bot.
        workers (:obj:`int`, optional): Amount of threads in the thread pool for functions
            decorated with ``@run_async``.
        bot (:class:`telegram.Bot`, optional): A pre-initialized bot instance. If a pre-initialized
            bot is used, it is the user's responsibility to create it using a `Request`
            instance with a large enough connection pool.
        user_sig_handler (:obj:`function`, optional): Takes ``signum, frame`` as positional
            arguments. This will be called when a signal is received, defaults are (SIGINT,
            SIGTERM, SIGABRT) setable with :attr:`idle`.
        request_kwargs (:obj:`dict`, optional): Keyword args to control the creation of a request
            object (ignored if `bot` argument is used).

    Note:
        You must supply either a :attr:`bot` or a :attr:`token` argument.

        ValueError: If both :attr:`token` and :attr:`bot` are passed or none of them.

class Updater(object):
    """
    This class, which employs the Dispatcher class, provides a frontend to
    telegram.Bot to the programmer, so they can focus on coding the bot. Its
    purpose is to receive the updates from Telegram and to deliver them to said
    dispatcher. It also runs in a separate thread, so the user can interact
    with the bot, for example on the command line. The dispatcher supports
    handlers for different kinds of data: Updates from Telegram, basic text
    commands and even arbitrary types.
    The updater can be started as a polling service or, for production, use a
    webhook to receive updates. This is achieved using the WebhookServer and
    WebhookHandler classes.


    Attributes:

    Args:
        token (Optional[str]): The bot's token given by the @BotFather
        base_url (Optional[str]):
        workers (Optional[int]): Amount of threads in the thread pool for
            functions decorated with @run_async
        bot (Optional[Bot]): A pre-initialized bot instance. If a pre-initizlied bot is used, it is
            the user's responsibility to create it using a `Request` instance with a large enough
            connection pool.
        job_queue_tick_interval(Optional[float]): The interval the queue should
            be checked for new tasks. Defaults to 1.0
