Interface Transformer<KeyInput extends ComputeKey<ResultInput>,ResultInput extends ComputeResult,ResultType extends ComputeResult>

Type Parameters:

KeyInput - the key type that the transform(Map) receive

ResultInput - the result type that the transform(Map) receive

ResultType - the type of the result from this transform

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 Transformer<KeyInput extends ComputeKey<ResultInput>,ResultInput extends ComputeResult,ResultType extends ComputeResult>

Generic transform API that given all dependencies through the ComputationEnvironment, computes the desired result of ResultType.
