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






The :obj:`~gi.repository.GObject.TypeValueTable` provides the functions required by the :obj:`~gi.repository.GObject.Value`
implementation, to serve as a container for values of a type.

   .. attribute:: collect_format

      A string format describing how to collect the contents of
        this value bit-by-bit. Each character in the format represents
        an argument to be collected, and the characters themselves indicate
        the type of the argument. Currently supported arguments are:
         - ``'i'``\: Integers, passed as ``collect_values[].v_int``
         - ``'l'``\: Longs, passed as ``collect_values[].v_long``
         - ``'d'``\: Doubles, passed as ``collect_values[].v_double``
         - ``'p'``\: Pointers, passed as ``collect_values[].v_pointer``
        It should be noted that for variable argument list construction,
        ANSI C promotes every type smaller than an integer to an int, and
        floats to doubles. So for collection of short int or char, ``'i'``
        needs to be used, and for collection of floats ``'d'``\.






   .. attribute:: collect_value

      Function to initialize a GValue from the values
        collected from variadic arguments






   .. attribute:: lcopy_format

      Format description of the arguments to collect for ``lcopy_value``\,
        analogous to ``collect_format``\. Usually, ``lcopy_format`` string consists
        only of ``'p'``\s to provide lcopy_value() with pointers to storage locations.






   .. attribute:: lcopy_value

      Function to store the contents of a value into the
        locations collected from variadic arguments






   .. attribute:: value_copy

      Function to copy a GValue






   .. attribute:: value_free

      Function to free a GValue






   .. attribute:: value_init

      Function to initialize a GValue






   .. attribute:: value_peek_pointer

      Function to peek the contents of a GValue if they fit
        into a pointer
