   Btw, I have a simple benchmark to compare the performance of get utitilty 
and the get accessor. 
   
   The result shows get accessor is slightly better than get utility:
   
   ```
   # Run complete. Total time: 00:03:36
   
   Benchmark                   Mode  Cnt     Score     Error   Units
   RowBenchmark.testAccessor  thrpt   20  4656.362 ± 355.096  ops/ms
   RowBenchmark.testUtility   thrpt   20  4933.103 ± 655.208  ops/ms
   ```
   
   Here is the code:
