Interface CoreFactory

public interface CoreFactory

Factory to create various objects for API interfaces. This class should never be used directly by application code and is only intended for internal usage in cds-services-api. Applications rather should use the specific create methods on the target interfaces. The implementation of the factory is loaded via ExtendedServiceLoader and is therefore pluggable.
