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.

Value parameters:
length

the desired length of the String

Returns:

the String
