createRandomIterator

public Iterator<Double> createRandomIterator(Random workingRandom)

Description copied from interface: ValueRange

Select in random order, but without shuffling the elements. Each element might be selected multiple times. Scales well because it does not require caching.

Parameters:

workingRandom - never null, the Random to use when any random number is needed, so EnvironmentMode.REPRODUCIBLE works correctly. RandomUtils can be useful too.

Returns:

never null
