	operator bool () const
	Test whether the Variant has an underlying instance.
void	init (const GVariant *cobject, bool take_a_reference=false)
	Replace the underlying GVariant.
VariantType	get_type () const
	Determines the type of value.
std::string	get_type_string () const
	Returns the type string of value.
bool	is_floating () const
	Checks whether value has a floating reference count.
bool	is_of_type (const VariantType & type) const
	Checks if a value has a type matching the provided type.
bool	is_container () const
	Checks if value is a container.
GVariantClass	classify () const
	Classifies value according to its top-level type.
gsize	get_size () const
	Determines the number of bytes that would be required to store value with g_variant_store().
gconstpointer	get_data () const
	Returns a pointer to the serialized form of a Variant instance.
Glib::RefPtr< const Glib::Bytes >	get_data_as_bytes () const
	Returns a pointer to the serialized form of a Variant instance.
void	store (gpointer data) const
	Stores the serialized form of value at data.
Glib::ustring	print (bool type_annotate=false) const
	Pretty-prints value in the format understood by g_variant_parse().
guint	hash () const
	Generates a hash value for a Variant instance.
