Method Detail

setRandomSeed

public void setRandomSeed(long randomSeed)

Description copied from interface: RandomSeedable

Sets the random seed to use. A class instance given the same configuration and random seed should produce the same method results when the same methods are called with the same parameters and in the same order. If this method is not called on a class instance, the random seed should be set to an arbitrary value (preferable to something non-constant, e.g., System.nanoTime()).

Specified by:

setRandomSeed in interface RandomSeedable

Parameters:

randomSeed - the random seed

getRandomSeed

public long getRandomSeed()

Description copied from interface: RandomSeedable

Returns the current random seed, which is the last seed set by setRandomSeed() or the initial random seed if setRandomSeed() hasn't been called before.

Specified by:

getRandomSeed in interface RandomSeedable

Returns:

the random seed
