------------------------------------
Summary: Allow to register TypeInfoFactories manually
Key: FLINK-4783
URL: https://issues.apache.org/jira/browse/FLINK-4783
Project: Flink
Issue Type: Improvement
Components: Type Serialization System
Affects Versions: 1.2.0
Reporter: Till Rohrmann
Priority: Minor
Fix For: 1.2.0
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.
