 ~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.
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 ()
 Returns a pointer to the serialised form of a Variant instance.
void store (gpointer data) const
 Stores the serialised 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 one and two have the same type and value.
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.

Static Public Member Functions

Constructor & Destructor Documentation

Default constructor.

Glib::Variant< Glib::ustring >::Variant ( GVariant< Glib::ustring >*  castitem,
bool  take_a_reference = false
