[jira] [Created] (ARROW-3475) C++ Int64Builder.Finish(NumericArray<Int64Type>)

Wolf Vollprecht created ARROW-3475:

             Summary: C++ Int64Builder.Finish(NumericArray<Int64Type>)
                 Key: ARROW-3475
                 URL: https://issues.apache.org/jira/browse/ARROW-3475
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wolf Vollprecht

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;}}

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?
