Attributes:
|

type (:obj:`type`): The ``type`` of updates this handler should process.
|
|
callback (:obj:`callable`): The callback function for this handler.
|
|
strict (:obj:`bool`): Optional. Use ``type`` instead of ``isinstance``.
|
|
Default is ``False``
|
|
pass_update_queue (:obj:`bool`): Optional. Determines whether ``update_queue`` will be
|
|
passed to the callback function.
|
|
pass_job_queue (:obj:`bool`): Optional. Determines whether ``job_queue`` will be passed to
|
|
the callback function.

Args:
|
|
type (:obj:`type`): The ``type`` of updates this handler should process, as

callback (:obj:`callable`): A function that takes ``bot, update`` as positional arguments.
|
|
It will be called when the :attr:`check_update` has determined that an update should be

|
processed by this handler.
|
|
strict (:obj:`bool`, optional): Use ``type`` instead of ``isinstance``.
|
|
Default is ``False``

|
pass_update_queue (:obj:`bool`, optional): If set to ``True``, a keyword argument called
|
|
``update_queue`` will be passed to the callback function. It will be the ``Queue``
|
|
instance used by the :class:`telegram.ext.Updater` and :class:`telegram.ext.Dispatcher`
|
|
that contains new updates which can be used to insert updates. Default is ``False``.

pass_job_queue (:obj:`bool`, optional): If set to ``True``, a keyword argument called
|
|
``job_queue`` will be passed to the callback function. It will be a

:class:`telegram.ext.JobQueue` instance created by the :class:`telegram.ext.Updater`
