Inheritance¶

Description¶

IInterfaceList is an interface for maintaining a list of interfaces, strongly resembling the standard TList class. It offers the same list of public methods as TList, with the exception that it uses interfaces instead of pointers.

All interfaces in the list should descend from IUnknown.

More detailed descriptions of how the various methods behave can be found in the TList reference.
