We've got a few generators for infinite streams already implemented. For object streams:

some wildcards are missing.

// produces seed, f(seed), f(f(seed)), ... iterate(T seed, UnaryOperator f) // infinite constant sequence repeat(T t) // finite constant sequence repeat(int n, T t) // infinite sequence driven by a supplier function repeatedly(Supplier f)

should be a Supplier(? extends T>.

// finite sequence driven by a supplier function repeatedly(int n, Supplier f) same as above.

// infinitely cycle through an Iterable cycle(Iterable iterable)

should be an Iterable<? extends T>.

For integer streams, the above, plus range(int from, int to) range(int from, int to, int step)
