Re: [aerogear-dev] Android library: Are nulls icky

In JS, there is just an array on the Pipeline/Auth/DataManager object instance that the developer just accesses directly to retrieve the pipe/module/store by name or index. If they reference one that doesn't exist, an error is thrown.

That said, I think on iOS (for now) i stay with the current approach returning 'nil' - if a store,pipe,(auth)module could not be found. I guess JS does the same.
