      public XoRoShiRo64StarStar(int[] seed)
      Creates a new instance.
      Parameters:
      seed - Initial seed. If the length is larger than 2, only the first 2 elements will be used; if smaller, the remaining elements will be automatically set. A seed containing all zeros will create a non-functional generator.

      public XoRoShiRo64StarStar(int seed0, int seed1)
      Creates a new instance using a 2 element seed. A seed containing all zeros will create a non-functional generator.
      Parameters:
      seed0 - Initial seed element 0.
      seed1 - Initial seed element 1.

    • nextOutput

      protected int nextOutput()
      Use the current state to compute the next output from the generator. The output function shall vary with respect to different generators. This method is called from AbstractXoRoShiRo64.next() before the current state is updated.
      Specified by:
      nextOutput in class AbstractXoRoShiRo64
      Returns:
      the next output
