ClassFactory Class

Article
04/28/2015

Implements the basic functionality of the IClassFactory interface.

template <
   typename I0 = Details::Nil,
   typename I1 = Details::Nil,
   typename I2 = Details::Nil
>
class ClassFactory : public Details::RuntimeClass<
   typename Details::InterfaceListHelper<IClassFactory, 
   I0, 
   I1, 
   I2, 
   Details::Nil>::TypeT, 
   RuntimeClassFlags<ClassicCom | InhibitWeakReference>, 
      false>;

Parameters

I0
The zeroth interface.
I1
The first interface.
I2
The second interface.

Remarks

Utilize ClassFactory to provide a user-defined factory implementation.

The following programming pattern demonstrates how to use the Implements structure to specify more than three interfaces on a class factory.

struct MyFactory : ClassFactory<Implements<I1, I2, I3>, I4, I5>
