[jira] [Created] (ARROW-1481) [C++] Expose type casts as generic callable object that can write into pre-allocated memory

Wes McKinney created ARROW-1481:
-----------------------------------

             Summary: [C++] Expose type casts as generic callable object that can write into pre-allocated memory
                 Key: ARROW-1481
                 URL: https://issues.apache.org/jira/browse/ARROW-1481
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney


Follow up to ARROW-229. Some projects may reuse temporary buffers, so presuming you know how much memory to allocate, you will want to be able to invoke the cast closures in generic way.

The API created in doing this should be deemed experimental as we iterate towards a more generic analytical kernel evaluation model
