    """Base class for all Filters.

    Filters subclassing from this class can combined using bitwise operators:

    And:

        >>> (Filters.text & Filters.entity(MENTION))

    Or:

        >>> (Filters.audio | Filters.video)

    Exclusive Or:

        >>> (Filters.regex('To Be') ^ Filters.regex('Not 2B'))

    Not:

        >>> ~ Filters.command

    Also works with more than two filters:

        >>> (Filters.text & (Filters.entity(URL) | Filters.entity(TEXT_LINK)))
        >>> Filters.text & (~ Filters.forwarded)

    Note:
        Filters use the same short circuiting logic as python's `and`, `or` and `not`.
        This means that for example:

            >>> Filters.regex(r'(a?x)') | Filters.regex(r'(b?x)')

        With ``message.text == x``, will only ever return the matches for the first filter,
        since the second one is never evaluated.


    If you want to create your own filters create a class inheriting from either
    :class:`MessageFilter` or :class:`UpdateFilter` and implement a :meth:`filter` method that
    returns a boolean: :obj:`True` if the message should be
    handled, :obj:`False` otherwise.
    Note that the filters work only as class instances, not
    actual class objects (so remember to
    initialize your filter classes).

    By default the filters name (what will get printed when converted to a string for display)
    will be the class name. If you want to overwrite this assign a better name to the :attr:`name`
    class variable.

    Attributes:
        name (:obj:`str`): Name for this filter. Defaults to the type of filter.
        data_filter (:obj:`bool`): Whether this filter is a data filter. A data filter should
            return a dict with lists. The dict will be merged with
            :class:`telegram.ext.CallbackContext`'s internal dict in most cases
            (depends on the handler).
