Fabian Hueske commented on FLINK-5358:
--------------------------------------
Very good point [~jark], in that case the type extraction would not work. We
could only default to {{GenericType}} which gives different behavior that
{{RowType}} because it is not a {{CompositeType}} and log a warning to
explicitly define the {{RowTypeInfo}}.
> Support RowTypeInfo extraction in TypeExtractor by Row instance

> Row[] data = new Row[]{};
> TypeInformation<X> typeInfo = TypeExtractor.getForObject(data[0]);
> {code}
> method {{getForObject}} wraps it into

> GenericTypeInfo<org.apache.flink.types.Row>

> the method should return {{RowTypeInfo}}
