> The newly introduced {{TypeInfoFactories}} (FLINK-3042 and FLINK-3060) allow to create {{TypeInformations}} for types which are annotated with {{TypeInfo}}. This is useful if the user has control over the type for which he wants to generate the {{TypeInformation}}.
> However, annotating a type is not always possible if the type comes from an external library. In this case, it would be good to be able to directly register a {{TypeInfoFactory}} without having to annotate the type.
> The {{TypeExtractor#registerFactory}} already has such a method. However, it is declared private.
