Such classes store their private data in a separate private data object, * referenced by a pointer in the public class (hence the name d-pointer). * * Classes that follow this design pattern are referred herein as extensible * classes. To be extensible, a class PublicClass shall: * * - inherit from the Extensible class or from another extensible class * - invoke the LIBCAMERA_DECLARE_PRIVATE() macro at the very top of the class * definition * - define a private data class named PublicClass::Private that inherits from * the Private data class of the base class * - invoke the LIBCAMERA_DECLARE_PUBLIC() macro at the very top of the Private * data class definition * - pass a pointer to a newly allocated Private data object to the constructor * of the base class * * Additionally, if the PublicClass is not final, it shall expose one or more * constructors that takes a pointer to a Private data instance, to be used by * derived classes. * * The Private class is fully opaque to users of the libcamera public API. * Internally, it can be kept private to the implementation of PublicClass, or * be exposed to other classes. In the latter case, the members of the Private * class need to be qualified with appropriate access specifiers. The * PublicClass and Private classes always have full access to each other's * protected and private members. */ /** * \brief Construct an instance of an Extensible class * \param[in] d Pointer to the private data instance */ Extensible::Extensible(Extensible::Private *d) : d_(d) { } /** * \var Extensible::d_ * \brief Pointer to the private data instance */ /** * \class Extensible::Private * \brief Base class for private data managed through a d-pointer */ /** * \brief Construct an instance of an Extensible class private data * \param[in] o Pointer to the public class object */ Extensible::Private::Private(Extensible *o) : o_(o) { } Extensible::Private::~Private() { } /** * \var Extensible::Private::o_ * \brief Pointer to the public class object */ } /* namespace libcamera */
