 Public Member Functions inherited from Harlinn::Common::Core::Unknown | |
| constexpr | Unknown () noexcept |
The default constructor ensures that the internal pointer to IUnknown is set to nullptr. | |
| Unknown (IUnknown *unknown, bool addref=false) noexcept | |
Constructs a new Unknown, taking ownership of the interface pointer held by unknown. | |
| Unknown (REFIID iid, const Unknown &unknown, bool throwIfNoInterface=true) | |
Initializes the new object to the interface identified by the iid parameter by querying the interface held by unknown for the requested interface. | |
| Unknown (const Unknown &other) noexcept | |
Copy constructor, calls AddRef on the interface pointer held by other. | |
| Unknown (Unknown &&other) noexcept | |
Move constructor takes ownership of the interface pointer held by other. | |
| ~Unknown () noexcept | |
Destructor, calling Release on the wrapped interface. | |
| constexpr | operator bool () const noexcept |
Returns true if this object references an interface. | |
| Unknown & | operator= (const Unknown &other) noexcept |
Copy assignment, which does nothing if other holds the same interface pointer as this object; and if not, calls Release on the currently held interface pointer, then copying the interface pointer from other, calling AddRef on the newly assigned interface pointer. | |
| Unknown & | operator= (Unknown &&other) noexcept |
Move assignment exchanges the current interface pointer, with the interface pointer held by other. | |
| void | swap (Unknown &other) noexcept |
Exchanges the current interface pointer, with the interface pointer held by other. | |
| void | ResetPtr (IUnknown *other=nullptr, bool addRef=false) noexcept |
Calls Release on the currently held interface pointer if the interface pointer held by other points to a different interface. | |
| Unknown & | operator= (nullptr_t) |
Assigning nullptr to the object, releases the currently held interface pointer, and sets the interface pointer to nullptr. | |
| IUnknown * | Detach () |
Returns the currently held interface pointer, setting the interface pointer of the object to nullptr. | |
| template<typename T > requires std::is_base_of_v<Unknown, T > | |
| T | As () const |
| Creates an instance of the interface wrapper class T, by querying the interface pointer for the interface type wrapped by T. | |
| template<typename T > requires std::is_base_of_v<Unknown, T> | |
| bool | Is () const noexcept |
Returns true if the interface can successfully be queried for the interface wrapped by T. | |
| template<typename T > requires std::is_base_of_v<IUnknown, T> | |
| ComPtr< T > | As () const |
| Creates an instance of the interface smart pointer ComPtr<T> for the interface T, by querying the interface pointer for the interface type T. | |
| template<typename T > requires std::is_base_of_v<IUnknown, T> | |
| bool | Is () const noexcept |
| This function can be used to detect if an object supports a particular COM interface derived from IUnknown. | |
| template<typename T = IUnknown> | |
| T * | GetInterfacePointer () const noexcept |
| Retrieves a pointer to the interface wrapped by this object. | |
| bool | QueryInterface (REFIID riid, void **itf) const |
| Queries a COM object for a pointer to one of its interface; identifying the interface by a reference to its interface identifier (IID). | |
| template<typename T > requires std::is_base_of_v<IUnknown, T> | |
| bool | QueryInterface (T **itf) const |
| Queries the interface for an interface pointer of type T. | |
| constexpr bool | operator== (const Unknown &other) const noexcept |
Returns true if the interface pointer held by this object is the same as the interface pointer held by the other object. | |
| constexpr bool | operator!= (const Unknown &other) const noexcept |
Returns true if the interface pointer held by this object is not the same as the interface pointer held by the other object. | |
| constexpr bool | operator== (const IUnknown *other) const noexcept |
Returns true if the interface pointer held by this object is the same as the interface pointer held by other. | |
| constexpr bool | operator!= (const IUnknown *other) const noexcept |
Returns true if the interface pointer held by this object is not the same as the interface pointer held by other. | |
