IInterface

  

Basic interface for all COM based interfaces.

Description

IVCLComObject is used by TComponent to implement the IUnknown interface used by COM automation servers. Partially, it is the translation to pascal of the IDispatch interface definition by Microsoft. If TComponent needs to return an IUnknown interface, it creates a IVCLComObject interface instead.
