Step 1 - Simple Creation

Start from branch master, solution is in branch solution/step1. You can look at the history of the solution to see changes in the services and implied modifications separately.

Migrate Services

• AdminService
• CoinService
• HashrateService
• PoolService

Useful Operators

• Observable.just
• Observable.from
• Observable.create (try it on PoolService.connect)
• map

How to easily (and naively) make things compile?

By blocking on the Observable<T>:

• first chain a toList() if expected result is a List<T>
• chain toBlocking()
• collect the result (or throw an Exception) with various operators
  • take(n)
  • single()
  • first()
  • last()
  • ???orDefault(T defaultValue)

A cleaner solution (going async all the way) will be presented later.
