> Key: FLINK-4783
> URL: https://issues.apache.org/jira/browse/FLINK-4783
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Affects Versions: 1.2.0
> Reporter: Till Rohrmann
> Assignee: Alexander Alexandrov
> Priority: Minor
> Labels: stale-minor
>
> 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.
