This time our Greeter is a factory. Each time a Customer comes in, we make the Greeter. (Don't worry, behind the scenes there is a cache.)
- Setup gains a
greeting factoryfunction which is registered in the registry - This function constructs the
Greeter - It's registered with
register_factoryinstead ofregister_singleton - That's it...our code doesn't know, when it asks for a
Greeter, that it came from a factory instead of a singleton
