This module contains filters for use with :class:`telegram.ext.MessageHandler`,
:class:`telegram.ext.CommandHandler`, or :class:`telegram.ext.PrefixHandler`.

.. versionchanged:: 20.0

    #. Filters are no longer callable, if you're using a custom filter and are calling an existing
       filter, then switch to the new syntax: ``filters.{filter}.check_update(update)``.
    #. Removed the ``Filters`` class. The filters are now directly attributes/classes of the
       :mod:`~telegram.ext.filters` module.
    #. The names of all filters has been updated:

       * Filter classes which are ready for use, e.g ``Filters.all`` are now capitalized, e.g
         ``filters.ALL``.
       * Filters which need to be initialized are now in CamelCase. E.g. ``filters.User(...)``.
       * Filters which do both (like ``Filters.text``) are now split as ready-to-use version
         ``filters.TEXT`` and class version ``filters.Text(...)``.

class BaseFilter:
    """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 :keyword:`and`, :keyword:`or` and
        :keyword:`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 ``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.

    .. versionadded:: 20.0
        Added the arguments :attr:`name` and :attr:`data_filter`.

    Args:
        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
