const mixinafIoc::RegistryShutdown

(Service) - Contribute functions to be executed on Registry shutdown. All functions need to be immutable, which essentially means they can only reference const classes. Example usage:

class AppModule {
    @Contribute { serviceType=RegistryShutdown# }
    static Void contributeRegistryShutdown(Configuration config, MyService myService) {
        config["myShutdownFunc"] = |->| { myService.shutdown() }
    }
}

If your shutdown method depends on other services still being available, add a constraint on their shutdown functions:

shutdownFunc := |->| { myService.shutdown() }
config.set("myShutdownFunc", shutdownFunc).before("otherShutdownFunc")

IoC also defines a general use constraint placeholder named afIoc.shutdown.

Note that any Errs thrown by shutdown functions will be logged and then swallowed.
