 Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.
 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::Bytesget_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.
bool equal (const VariantBase &other) const
 Checks if *this and other have the same type and value.
bool operator== (const VariantBase &other) const
 Checks if *this and other have the same type and value.
bool operator!= (const VariantBase &other) const
 Checks if *this and other have the same type and value.
bool operator< (const VariantBase &other) const =delete
 Ordering relational operators.

 See operator<().
bool operator>= (const VariantBase &other) const =delete
 See operator<().
void get_normal_form (VariantBase &result) const
 Gets a VariantBase instance that has the same value as this variant and is trusted to be in normal form.
bool is_normal_form () const
 Checks if value is in normal form.
void byteswap (VariantBase &result) const
 Performs a byteswapping operation on the contents of this variant.
bool check_format_string (const std::string & format_string, bool copy_only=false) const
 Checks if calling g_variant_get() with format_string on value would be valid from a type-compatibility standpoint.
template<typename ValueType >
ValueType get_dynamic () const
 Cast to a specific variant type and get the value.
