"""Using python's builtin :mod:`pickle` for making your bot persistent.
Attention:
The interface provided by this class is intended to be accessed exclusively by
:class:`~telegram.ext.Application`. Calling any of the methods below manually might
interfere with the integration of persistence into :class:`~telegram.ext.Application`.
Note:
This implementation of :class:`BasePersistence` uses the functionality of the pickle module
to support serialization of bot instances. Specifically any reference to
:attr:`~BasePersistence.bot` will be replaced by a placeholder before pickling and
:attr:`~BasePersistence.bot` will be inserted back when loading the data.
Examples:
:any:`Persistent Conversation Bot <examples.persistentconversationbot>`
.. seealso:: :wiki:`Making Your Bot Persistent <Making-your-bot-persistent>`
.. versionchanged:: 20.0
* The parameters and attributes ``store_*_data`` were replaced by :attr:`store_data`.
* The parameter and attribute ``filename`` were replaced by :attr:`filepath`.
* :attr:`filepath` now also accepts :obj:`pathlib.Path` as argument.
Args:
filepath (:obj:`str` | :obj:`pathlib.Path`): The filepath for storing the pickle files.
When :attr:`single_file` is :obj:`False` this will be used as a prefix.
store_data (:class:`~telegram.ext.PersistenceInput`, optional): Specifies which kinds of
data will be saved by this persistence instance. By default, all available kinds of
data will be saved.
2021-06-06 11:48:48 +02:00
single_file (:obj:`bool`, optional): When :obj:`False` will store 5 separate files of
`filename_user_data`, `filename_bot_data`, `filename_chat_data`,
2021-06-06 11:48:48 +02:00
`filename_callback_data` and `filename_conversations`. Default is :obj:`True`.

on_flush (:obj:`bool`, optional): When :obj:`True` will only save to file when
:meth:`flush` is called and keep data in memory until that happens. When
:obj:`False` will store data on any transaction *and* on call to :meth:`flush`.
Default is :obj:`False`.
context_types (:class:`telegram.ext.ContextTypes`, optional): Pass an instance
of :class:`telegram.ext.ContextTypes` to customize the types used in the
``context`` interface. If not passed, the defaults documented in
:class:`telegram.ext.ContextTypes` will be used.
.. versionadded:: 13.6
update_interval (:obj:`int` | :obj:`float`, optional): The
:class:`~telegram.ext.Application` will update
the persistence in regular intervals. This parameter specifies the time (in seconds) to
wait between two consecutive runs of updating the persistence. Defaults to 60 seconds.

Attributes:
filepath (:obj:`str` | :obj:`pathlib.Path`): The filepath for storing the pickle files.
