 VariantContainerBase ()
 Default constructor.
 VariantContainerBase (GVariant* castitem, bool take_a_reference=false)
 GVariant constructor.
gsize get_n_children () const
 Determines the number of children in a container Variant instance.
void get_child (VariantBase& child, gsize index=0) 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.
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.

Detailed Description

template<>
class Glib::Variant< std::vector< Glib::ustring > >

Specialization of Variant containing an array of UTF-8 capable strings.

Since glibmm 2.28:

Member Typedef Documentation

Reimplemented from Glib::VariantContainerBase.


Constructor & Destructor Documentation

Default constructor.

Glib::Variant< std::vector< Glib::ustring > >::Variant ( GVariant< std::vector< Glib::ustring > >*  castitem,
bool  take_a_reference = false 
)
explicit

GVariant constructor.

Parameters:
castitemThe GVariant to wrap.
take_a_referenceWhether to take an extra reference of the GVariant or not (not taking one could destroy the GVariant with the wrapper).

Member Function Documentation

Creates a new Variant from an array of strings.

Parameters:
dataThe array to use for creation.
Returns:
The new Variant.
Since glibmm 2.28:

Gets the string vector of the Variant.

Returns:
The vector.
Since glibmm 2.28:
Glib::ustring Glib::Variant< std::vector< Glib::ustring > >::get_child ( gsize  index) const

Gets a specific element of 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).

Parameters:
indexThe index of the element.
Returns:
The element at index .
Exceptions:
std::out_of_range
Since glibmm 2.28:

Gets a VariantIter of the Variant.

Returns:
the VaraintIter.
Since glibmm 2.28:
static const VariantType& Glib::Variant< std::vector< Glib::ustring > >::variant_type ( )
static

Gets the VariantType.

Returns:
The VariantType.
