Uwe L. Korn commented on ARROW-3475:
------------------------------------

Yes, definitely!

>                 Key: ARROW-3475
>                 URL: https://issues.apache.org/jira/browse/ARROW-3475
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: C++
>            Reporter: Wolf Vollprecht
>            Priority: Minor
>
> I was intuitively thinking that the following code would work:
> {{Status s;}}
> {{Int64Builder builder;}}
> {{s = builder.Append(1);}}
> {{s = builder.Append(2);}}
> {{std::shared_ptr<NumericArray<Int64Type>> array;}}
> {{builder.Finish(&array);}}
> However, it does not seem to work, as the finish operation is not overloaded in the Int64 (or the numeric builder).
> Would it make sense to add this interface?
