Public Member Functions
void	AcquireResource (LONG idResource) const
void	ReleaseResource (LONG idResource) const
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.
