Dawid Wysakowicz commented on FLINK-3574:
-----------------------------------------
I have some conceptual problem cause all of those functions take as parameters
all NUMERIC types so that I can't use current concept with CallGenerator(needs
specific type).
I thought about writing it as all the comparisons and arithmetic operators but
then it would be best to extract method for generating code with method call
(from MethodCallGenerator).
I also wonder if we want two different ways of processing - both in
CodeGenerator::visitCall and in RexNodeTranslator::toRexNode.
I hope I described it pretty clearly, but to sum up the biggest problem I have
is how to handle all NUMERIC types at once.
