ProtectedconstructorStaticInstanceThe singleton accessor, keyed by this class's name in the Global Object Store (via BaseSingleton).
The Global Object Store is a place to store global objects that need to be shared across the application. Depending on the execution environment, this could be the window object in a browser, or the global object in a node environment, or something else in other contexts. The key here is that in some cases static variables are not truly shared because it is possible that a given class might have copies of its code in multiple paths in a deployed application. This approach ensures that no matter how many code copies might exist, there is only one instance of the object in question by using the Global Object Store.
Boot entry point (per IStartupSink). Registers the ML scoring processor for the
'ML Model' work type with the production deps bundle. No-op-safe to call more than once
(the registry last-wins), and needs neither the contextUser nor provider — the deps are
constructed without them and take a provider/user per scoring call.
Optional_contextUser: UserInfounused — the registration is provider/user-agnostic at construction time
Optional_provider: IMetadataProviderunused — see above
Protected StaticgetReturns the singleton instance of the class. If the instance does not exist, it is created and stored in the Global Object Store. If className is provided it will be used as part of the key in the Global Object Store, otherwise the actual class name will be used. NOTE: the class name used by default is the lowest level of the object hierarchy, so if you have a class that extends another class, the lowest level class name will be used.
OptionalclassName: string
Startup sink that registers the Predictive Studio
'ML Model'(and'MLModelInference'alias) scoring processor into the Record Set Processing RecordProcessorRegistry, so a savedMJ: Record Processesrow withWorkType='ML Model'routes to the scorer live.The registration is idempotent (last-wins) and provider-agnostic — the injected seams receive their
provider+userper scoring call — so HandleStartup needs no body beyond the single register call. Discovered via the@RegisterForStartupdecorator + the class manifest.
