I just think it is best for a java developer has more specific way to
control the return type. Like current there is these version of methods to
access row by index.
Because I move my code base from getString(int) like method, so it is a bit
lazy for me to change everywhere. So I think if I need to have these helper
method, I just add them to the code, so make it consistent with current method
style.
But I have no preference on whether we must have this. If here people think
we better don't have these, I will delete the pull request :).
And to me, if we don't have these, I will say we better only keep
getAs[T](int) and getAs[T](String), instead of only have getString(int index)
like method without similar getString(String fieldName)
