public interface Function2<X,Y,Z>
extends java.io.Serializable

Represents a two-argument function We could as well use Google guava library, but Guava's functions are not serializable. We need serializable functions, to be able to pass them over the cloud. A two-argument function, in abstract settings, is something that takes values of given type (X and Y) and returns a value of a given type (Z).
