public interface ColumnAccessor
An Iterator like trait used to extract values from columnar byte buffer. When a value is
extracted from the buffer, instead of directly returning it, the value is set into some field of
a MutableRow. In this way, boxing cost can be avoided by leveraging the setter methods
for primitive values provided by MutableRow.
