|
This class is a :class:`~typing.Generic` class and accepts one type variable that specifies
|
|
the type of the argument ``context`` of the job callbacks (:paramref:`~run_once.callback`) of
|
|
:meth:`run_once` and the other scheduling methods.
|
|
|
|
Important:
|
|
If you want to use this class, you must install PTB with the optional requirement
|
|
``job-queue``, i.e.
|
|
|
|
.. code-block:: bash
|
|
|
|
pip install "python-telegram-bot[job-queue]"

|
|
:wiki:`Job Queue <Extensions---JobQueue>`

To use this class, PTB must be installed via

Warning:
|
|
This scheduler is configured by :meth:`set_application`. Additional configuration

settings can be made by users. However, calling

:meth:`~apscheduler.schedulers.base.BaseScheduler.configure` will delete any
|
|
previous configuration settings. Therefore, please make sure to pass the values
|
|
returned by :attr:`scheduler_configuration` to the method call in addition to your
|
|
custom values.
|
|
Alternatively, you can also use methods like
|
|
:meth:`~apscheduler.schedulers.base.BaseScheduler.add_jobstore` to avoid using
|
|
:meth:`~apscheduler.schedulers.base.BaseScheduler.configure` altogether.
