| void | swap (VariantBase &other) noexcept |
| GVariant * | gobj () |
| const GVariant * | gobj () const |
| GVariant * | gobj_copy () const |
| 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::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. | |
| 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. | |
| bool | operator<= (const VariantBase &other) const =delete |
| See operator<(). | |
| bool | operator> (const VariantBase &other) const =delete |
| 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. | |
| Static Public Member Functions inherited from Glib::VariantBase | |
| template<class V_CastTo > | |
| static V_CastTo | cast_dynamic (const VariantBase &v) |
| Cast to a specific variant type. | |

| template<typename T > | |
| Variant< T > | create_variant (const T &data) |
| Creates a Glib::Variant instance. | |
| void | swap (VariantBase &lhs, VariantBase &rhs) noexcept |
| Glib::VariantBase | wrap (GVariant *object, bool take_copy=false) |
