> class MySource<T> implements SourceFunction<T>, ResultTypeQueryable<T> {
> TypeInformation getProducedType() {
> return TypeExtractor.createTypeInfo(SourceFunction.class, this.getClass(),
> 0, null, null);
> }
> }
> DataStream ds = tEnv.addSource(new MySource(), Types.ROW(Types.STRING))
> {code}
> The returned {{TypeInformation}} of {{MySource}} is {{GenericTypeInfo}}, not
> the user given {{RowTypeInfo}}.
> It seems that {{StreamExecutionEnvironment#getTypeInfo}} doesn't use the user
> given {{typeInfo}} in the highest priority.
