Interface FrameCombinerFactory

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface FrameCombinerFactory
Factory for creating FrameCombiner instances. This interface exists because FrameCombiner objects are stateful (they accumulate values across rows within a group), so each merge operation needs its own instance.
