Multiplexing the Future<> in Java

Question

I find myself about to write a class that implements Future<T> and stores, inside of itself, a Collection<Future<T>>, acting as an aggregate future for all of its contents.

I wonder: has anyone already done this in some open source library? A bit of googling didn't yield.

Answer 1

Depends what you mean by "aggregate future." Perhaps Guava's Futures.allAsList?
