Implements the basic functionality of the IClassFactory interface.

Syntax

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>
