Public Types | |
typedef char* | CType |
typedef std::string | CppType |
![]() | |
typedef GVariant* | CType |
typedef VariantStringBase | CppType |

typedef const void* | BoolExpr |
This typedef is just to make it more obvious that our operator const void* should be used like operator bool(). More... | |
Public Member Functions | |
Variant () | |
Default constructor. More... | |
Variant (GVariant* castitem, bool take_a_reference=false) | |
GVariant constructor. More... | |
std::string | get () const |

~VariantBase () | |
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. More... | |
operator BoolExpr () const | |
Test whether the Variant has an underlying instance. More... | |
void | init (const GVariant* cobject, bool take_a_reference=false) |
Replace the underlying GVariant. More... | |
VariantType | get_type () const |
Determines the type of value. More... | |
std::string | get_type_string () const |
Returns the type string of value. More... | |
bool | is_floating () const |
Checks whether value has a floating reference count. More... | |
bool | is_of_type (const VariantType& type) const |
Checks if a value has a type matching the provided type. More... | |
bool | is_container () const |
Checks if value is a container. More... | |
GVariantClass | classify () const |
Classifies value according to its top-level type. More... | |
gsize | get_size () const |
Determines the number of bytes that would be required to store value with g_variant_store(). More... | |
gconstpointer | get_data () |
Returns a pointer to the serialised form of a Variant instance. More... | |
void | store (gpointer data) const |
Stores the serialised form of value at data. More... | |
Glib::ustring | print (bool type_annotate=false) const |
Pretty-prints value in the format understood by g_variant_parse(). More... | |
guint | hash () const |
Generates a hash value for a Variant instance. More... | |
bool | equal (const VariantBase& other) const |
Checks if *this and other have the same type and value. More... | |
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. More... | |
bool | is_normal_form () const |
Checks if value is in normal form. More... | |
void | byteswap (VariantBase& result) const |
Performs a byteswapping operation on the contents of this variant. More... | |
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. More... | |
template<> | |
VariantContainerBase | cast_dynamic (const VariantBase& v) throw (std::bad_cast) |
Static Public Member Functions | |
static const VariantType& | variant_type () |
Gets the VariantType. More... | |
static Variant< std::string > | create (const std::string& data) |
Creates a new Variant<std::string>. More... | |
![]() | |
static void | create_object_path (VariantStringBase& output, const std::string& object_path) |
Creates a D-Bus object path variant with the contents of string. More... | |
