Public Member Functions | |
Variant () | |
Default constructor. | |
Variant (GVariant* castitem, bool take_a_reference=false) | |
GVariant constructor. | |
std::pair< K, V > | get_child (gsize index) const |
Gets a specific dictionary entry from the string array. | |
bool | lookup (const K& key, V&value) const |
Looks up a value in a dictionary Variant. | |
std::map< K, V > | get () const |
Gets the map (the dictionary) of the Variant. | |
VariantIter | get_iter () const |
Gets a VariantIter of the Variant. | |
Static Public Member Functions | |
static const VariantType& | variant_type () |
Gets the VariantType. | |
static Variant< std::map< K, V > > | create (const std::map< K, V >& data) |
Creates a new Variant containing a dictionary from a map. |
Specialization of Variant containing a dictionary (a map of (key, value) elements).
typedef std::map<K, V> Glib::Variant< std::map< K, V > >::CppContainerType |
typedef std::pair<K, V> Glib::Variant< std::map< K, V > >::CppType |
Reimplemented from Glib::VariantContainerBase.
Glib::Variant< std::map< K, V > >::Variant | ( | ) | [inline] |
Default constructor.
Glib::Variant< std::map< K, V > >::Variant | ( | GVariant< std::map< K, V > > * | castitem, |
bool | take_a_reference = false |
||
) | [inline, explicit] |
GVariant constructor.
castitem | The GVariant to wrap. |
take_a_reference | Whether to take an extra reference of the GVariant or not (not taking one could destroy the GVariant with the wrapper). |
Variant< std::map< K, V > > Glib::Variant< std::map< K, V > >::create | ( | const std::map< K, V > & | data | ) | [static] |
std::map< K, V > Glib::Variant< std::map< K, V > >::get | ( | ) | const |
std::pair< K, V > Glib::Variant< std::map< K, V > >::get_child | ( | gsize | index | ) | const |
Gets a specific dictionary entry from the string array.
It is an error if index is greater than the number of child items in the container. See VariantContainerBase::get_n_children().
This function is O(1).
index | The index of the element. |
std::out_of_range |
VariantIter Glib::Variant< std::map< K, V > >::get_iter | ( | ) | const |
bool Glib::Variant< std::map< K, V > >::lookup | ( | const K & | key, |
V & | value | ||
) | const |
Looks up a value in a dictionary Variant.
key | The key to look up. |
value | A location in which to store the value if found. |
true
if the key is found, false
otherwise. const VariantType& Glib::Variant< std::map< K, V > >::variant_type | ( | ) | [static] |
