How to use this?

The best examples can be found in this unit test

Examples (in groovy):

			/* My long running function here converts a appends the string with a % sign */
			def results = Lists.applyNWorkers(["1", "2", "3"], [], new LongRunningFunction(), 2)
			results == ["A%, B%, C%"]
			
			/* This one applies 2 workers to work through the list */

Why was this created?

This project started off as a learning exercise. One fine weekend I wanted to learn Akka with Java. In the process I created this github project to capture my learnings. The folders one - five in here is where that learning was captured. As I did that I realized a simple utility can be created that can be used with any traditional java code - specially unit tests or just for curious minds. This utility will process a list, apply a long running function (like making service calls) to each element in the list, capture results, aggregate them and will return the results. The results will be returned in the order - one for each element in the input list. Thus, this utility was created.

Why would I use this?

I would recommend not to use this in production code, yet.

Use this utility in your unit tests to exercise parallel processing / concurrency.

For curious minds - to try out some instrumentation on your services

For learning
