ActivationFactory Class

Article
07/11/2012

Enables one or more classes to be activated by the Windows Runtime.

template <
   typename I0 = Details::Nil,
   typename I1 = Details::Nil,
   typename I2 = Details::Nil
>
class ActivationFactory : public Details::RuntimeClass<typename Details::InterfaceListHelper<IActivationFactory, I0, I1, I2, Details::Nil>::TypeT, RuntimeClassFlags<WinRt | InhibitWeakReference>, false>;

Parameters

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

Remarks

ActivationFactory provides registration methods and basic functionality for the IActivationFactory interface. ActivationFactory also enables you to provide a custom factory implementation.

The following code fragment symbolically illustrates how to use ActivationFactory.

struct MyClassFactory : public ActivationFactory
{
       STDMETHOD(ActivateInstance)(_Outptr_result_nullonfailure_ IInspectable **ppvObject)
       {
           // my custom implementation
       }
};
ActivatableClassWithFactory(MyClass, MyClassFactory);
// or if a default factory is used:
ActivatableClassWithFactory(MyClass, SimpleActivationFactory);

The following code fragment shows how to use the Implements structure to specify more than three interface IDs.

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