  18. def nextString(length: Int): String

    Returns a pseudorandomly generated String.

    Returns a pseudorandomly generated String. This routine does not take any measures to preserve the randomness of the distribution in the face of factors like unicode's variable-length encoding, so please don't use this for anything important. It's primarily intended for generating test data.
