Subclass this object for different implementations of a persistent bot.

All relevant methods must be overwritten. This includes:

If you don't actually need one of those methods, a simple ``pass`` is enough. For example, if

:meth:`refresh_bot_data`.

Warning:
|
|
Persistence will try to replace :class:`telegram.Bot` instances by :attr:`REPLACED_BOT` and
|
|
insert the bot set with :meth:`set_bot` upon loading of the data. This is to ensure that
|
|
changes to the bot apply to the saved objects, too. If you change the bots token, this may
|
|
lead to e.g. ``Chat not found`` errors. For the limitations on replacing bots see
|
|
:meth:`replace_bot` and :meth:`insert_bot`.
|
|
|
|
Note:
|
|
:meth:`replace_bot` and :meth:`insert_bot` are used *independently* of the implementation
|
|
of the :meth:`update/get_*` methods, i.e. you don't need to worry about it while
|
|
implementing a custom persistence subclass.
