Examples of com.facebook.LinkBench.distributions.ProbabilityDistribution.choose()

com.facebook.LinkBench.distributions.ProbabilityDistribution.choose()
Choose a random id in range [min, max) according to the probability distribution. @param rng a random number generator to use for random choice @return the chosen id

    ProbabilityDistribution dist = getDist();
    long min = 453, max = 26546454;
    dist.init(min, max, getDistParams(), "");
    Random rng = initRandom("testChooseSanity");
    for (int i = 0; i < 100000; i++) {
      long id = dist.choose(rng);
      assertTrue(id >= min);
      assertTrue(id < max);
    }
  }
