Zip/Map/Select with index

[samuelgruetter]

I'm looking for a function corresponding to this Rx C# function:

Do we already have this in RxJava? I'm asking this because I want to implement the zipWithIndex function in the Scala adaptor.

No we do not have that yet. Your naming convention will be what we need to use so we don't overload methods with functions of different arities as that causes issues.

So mapWithIndex and zipWithIndex make sense.

[samuelgruetter]

I'd be happy with mapWithIndex and zipWithIndex.

I don't think we have the arity problem with map (mapWithIndex), or do we? I think it should be specific to zip. So we could name it map instead of mapWithIndex if we wanted to. But probably we should be consistent and still call it mapWithIndex.

[jmhofer]

I take that back. I just experimented with this and noticed that at least Clojure does indeed have a problem with that. So mapWithIndex it is.
