ValueList
===================================================================

.. currentmodule:: gi.repository.Gst





.. class:: ValueList(*args, **kwargs)
   :no-contents-entry:






A fundamental type that describes an unordered list of :obj:`~gi.repository.GObject.Value`




Methods
-------

.. rst-class:: interim-class

.. class:: ValueList
   :no-index:


   .. classmethod:: append_and_take_value(append_value: ~gi.repository.GObject.Value) -> None

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


      .. versionadded:: 1.2





      :param append_value: the value to append




   .. classmethod:: append_value(append_value: ~gi.repository.GObject.Value) -> None

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






      :param append_value: the value to append




   .. classmethod:: concat(value2: ~gi.repository.GObject.Value) -> ~gi.repository.GObject.Value

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




   .. classmethod:: get_size() -> int

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









   .. classmethod:: get_value(index: int) -> ~gi.repository.GObject.Value

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






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




   .. classmethod:: init(prealloc: int) -> ~gi.repository.GObject.Value

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


      .. versionadded:: 1.18





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




   .. classmethod:: merge(value2: ~gi.repository.GObject.Value) -> ~gi.repository.GObject.Value

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




   .. classmethod:: prepend_value(prepend_value: ~gi.repository.GObject.Value) -> None

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






      :param prepend_value: the value to prepend
