Letâs check if I understood this method.
It will look up for a naming policy that is registered given a naming
policy class, right?
The registered policy is an instance of that class that is sent as a
parameter, right? If I already know the class I need, why look for an instance
of it?
What about creating singletons those classes using spring? And then, just
injecting them where needed. Sorry if overlooked something, but have you tried
to design some solution that uses IoC instead of creating our own?
