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`.
