rnStream

Tells the provider to return the ith stream of the sequence of streams that it provides. If i = 0, then the next stream in the sequence of streams is return. If i < 0, then the antithetic stream associated with stream abs(i) is returned. The antithetic stream will not be managed by the provider but stream abs(i) will be managed. That is, antithetic streams are not subject to the stream control; however a standard stream that has been told to produce antithetic PRNs via its antithetic property will be controlled by the provider.

If abs(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 abs(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.
