randomOrderedKey

public static byte[] randomOrderedKey(Random rand,
                                      int i)

Generates a random key that is guaranteed to increase as the given index i increases. The result consists of a prefix, which is a deterministic increasing function of i, and a random suffix.

Parameters:

rand - random number generator to use

i -

Returns:
