QueueingStrategy enum
~~~~~~~~~~~~~~~~~~~~~

*Namespace:* ``P1.CameraSdk``


Definition
^^^^^^^^^^

Strategies for queueing :ref:`INotificationEvent <doxcsid-interface_p1_1_1_camera_sdk_1_1_i_notification_event>` on listener queues

Used by CameraSDK internals to decide how (and if) an incoming :ref:`INotificationEvent <doxcsid-interface_p1_1_1_camera_sdk_1_1_i_notification_event>` should be added to :ref:`Listener <doxcsid-class_p1_1_1_camera_sdk_1_1_listener>` queues.

Each *notification event* defines a queueing strategy, that is consulted when new notifications are added to the :ref:`Listener <doxcsid-class_p1_1_1_camera_sdk_1_1_listener>`.
