Methods
-------

.. rst-class:: interim-class

.. class:: ValueList
   :no-index:


   .. method:: append_and_take_value(value: ~typing.Any, append_value: ~typing.Any) -> None

      Appends ``append_value`` to the GstValueList in ``value``.



      .. versionadded:: 1.2





      :param value: a :obj:`~gi.repository.GObject.Value` of type ``GST_TYPE_LIST``


      :param append_value: the value to append





   .. method:: append_value(value: ~typing.Any, append_value: ~typing.Any) -> None

      Appends ``append_value`` to the GstValueList in ``value``.







      :param value: a :obj:`~gi.repository.GObject.Value` of type ``GST_TYPE_LIST``


      :param append_value: the value to append





   .. method:: concat(value1: ~typing.Any, value2: ~typing.Any) -> ~typing.Any

      Concatenates copies of ``value1`` and ``value2`` into a list.  Values that are not
      of type ``GST_TYPE_LIST`` are treated as if they were lists of length 1.
      ``dest`` will be initialized to the type ``GST_TYPE_LIST``.







      :param value1: a :obj:`~gi.repository.GObject.Value`


      :param value2: a :obj:`~gi.repository.GObject.Value`





   .. method:: get_size(value: ~typing.Any) -> int

      Gets the number of values contained in ``value``.







      :param value: a :obj:`~gi.repository.GObject.Value` of type ``GST_TYPE_LIST``





   .. method:: get_value(value: ~typing.Any, index: int) -> ~typing.Any

      Gets the value that is a member of the list contained in ``value`` and
      has the index ``index``.







      :param value: a :obj:`~gi.repository.GObject.Value` of type ``GST_TYPE_LIST``


      :param index: index of value to get from the list





   .. method:: init(value: ~typing.Any, prealloc: int) -> ~typing.Any

      Initializes and pre-allocates a :obj:`~gi.repository.GObject.Value` of type ``GST_TYPE_LIST``.



      .. versionadded:: 1.18





      :param value: A zero-filled (uninitialized) :obj:`~gi.repository.GObject.Value` structure


      :param prealloc: The number of entries to pre-allocate in the list





   .. method:: merge(value1: ~typing.Any, value2: ~typing.Any) -> ~typing.Any

      Merges copies of ``value1`` and ``value2``.  Values that are not
      of type ``GST_TYPE_LIST`` are treated as if they were lists of length 1.

      The result will be put into ``dest`` and will either be a list that will not
      contain any duplicates, or a non-list type (if ``value1`` and ``value2``
      were equal).







      :param value1: a :obj:`~gi.repository.GObject.Value`


      :param value2: a :obj:`~gi.repository.GObject.Value`





   .. method:: prepend_value(value: ~typing.Any, prepend_value: ~typing.Any) -> None

      Prepends ``prepend_value`` to the GstValueList in ``value``.







      :param value: a :obj:`~gi.repository.GObject.Value` of type ``GST_TYPE_LIST``


      :param prepend_value: the value to prepend
