Functions.identity() equivalent (original) (raw)

Long::longValue?

It's not shorter than l -> l though.

Cheers, Henry

Hi guys,

One common scenario here is having a Map<Something, Long> and wanting to do something with the values. So I (think I) have to do: totalBySomething.values().parallelStream().mapToLong(l -> l)... because I cannot use Functions.identity() here. This shows up pretty often. Anything planned for that? Regards, Michael
