rnStream

Tells the provider to return the ith stream of the sequence of streams that it provides. If i is greater than lastRNStreamNumber() then lastRNStreamNumber() is advanced according to the additional number of streams. For example, if lastRNStreamNumber() = 10 and i = 15, then streams 11, 12, 13, 14, 15 are assumed provided and stream 15 is returned and lastRNStreamNumber() now equals 15. If i is less than or equal to lastRNStreamNumber(), then no new streams are created, lastRNStreamNumber() stays at its current value and the ith stream is returned.
