You can also delegate the inplemenation of an interface in delphi
So in your case ClassC inherits from ClassA and implements InterfaceB
(defined alongside ClassB)
ClassC has a subject of Class B which it delegates its implementation of
InterfaceB to
ie
TClassC - class(TClassA, InterfaceB)
private
FClassB: TClassB
property
InstClassB read FClassB write FClassB implements InterfaceB
end
I think this is called a 'decorator' patten
