Review Comment:
When you move the exception from constructor, you should see
`AnalysisException` w/ an error class.

Review Comment:
Could you perform the check in `checkInputDataTypes()` as we do that in
other expression, please.
BTW, exceptions from expressions constructors are wrapped by
`AnalysisException` additionally which is not convenient to users.
