IInterface is the base class for all interfaces defined in Delphi code.
IInterface is the base interface for interfaces defined in Delphi code. When used in C++ code, IInterface is considered a child interface of IUnknown and IUnknown is considered the base interface for all interfaces.
Note: IInterface introduces the QueryInterface method, which is useful for discovering and using other interfaces implemented by the same object. IInterface also introduces the reference counting methods, _AddRef and _Release. The Delphi compiler automatically provides calls to these methods when interfaces are used. The TInterfacedObject class is provided as a base class for objects that implement interfaces. Use of TInterfacedObject is not mandatory, but will often be easier than designing an implementer class from scratch.
