public interface Fn2<I1,I2,O>
extends Serializable

Function taking two values of type I1 and I2, and returning a value of type O.

 ƒ(I1,I2) ∈ O
 

This function type is often referred to as a "reducer" as it yields one value based on two input values, and it can be applied recursively to reduce an arbitrary amount of elements to one.
