95 * This is the default constructor for this class. @n
96 * The object is not fully constructed after this constructor is called. @n
97 * For full construction, the Construct() method must be called right after calling this constructor.

104 * This is the destructor for this class. @n
105 * The resources are deallocated by this method.
106 * This destructor overrides Tizen::Base::Object::~Object().

113 * Initializes this instance of %QRCodeGenerator. @n
114 * Every application must call %Construct() before calling any other methods of %QRCodeGenerator.
