Methods
-------

.. rst-class:: interim-class

.. class:: DeviceProviderFactory
   :no-index:


   .. method:: find(name: str) -> ~gi.repository.Gst.DeviceProviderFactory | None

      Search for an device provider factory of the given name. Refs the returned
      device provider factory; caller is responsible for unreffing.



      .. versionadded:: 1.4





      :param name: name of factory to find





   .. method:: get() -> ~gi.repository.Gst.DeviceProvider | None

      Returns the device provider of the type defined by the given device
      providerfactory.



      .. versionadded:: 1.4








   .. method:: get_by_name(factoryname: str) -> ~gi.repository.Gst.DeviceProvider | None

      Returns the device provider of the type defined by the given device
      provider factory.



      .. versionadded:: 1.4





      :param factoryname: a named factory to instantiate





   .. method:: get_device_provider_type() -> type

      Get the :obj:`~gi.repository.GObject.Type` for device providers managed by this factory. The type can
      only be retrieved if the device provider factory is loaded, which can be
      assured with :func:`~gi.repository.Gst.PluginFeature.load`.



      .. versionadded:: 1.4








   .. method:: get_metadata(key: str) -> str | None

      Get the metadata on ``factory`` with ``key``.



      .. versionadded:: 1.4





      :param key: a key





   .. method:: get_metadata_keys() -> list[str] | None

      Get the available keys for the metadata on ``factory``.



      .. versionadded:: 1.4








   .. method:: has_classes(classes: str | None = None) -> bool

      Check if ``factory`` matches all of the given ``classes``



      .. versionadded:: 1.4





      :param classes: a "/" separate list of classes to match, only match
         if all classes are matched





   .. method:: has_classesv(classes: ~typing.Sequence[str] | None = None) -> bool

      Check if ``factory`` matches all of the given classes



      .. versionadded:: 1.4





      :param classes: a :const:`None` terminated array
         of classes to match, only match if all classes are matched





   .. method:: list_get_device_providers(minrank: ~gi.repository.Gst.Rank) -> list[~gi.repository.Gst.DeviceProviderFactory]

      Get a list of factories with a rank greater or equal to ``minrank``.
      The list of factories is returned by decreasing rank.



      .. versionadded:: 1.4





      :param minrank: Minimum rank
