If the length is larger than 16, only the first 16 elements will
be used; if smaller, the remaining elements will be automatically
set. A seed containing all zeros will create a non-functional generator.protected XoRoShiRo1024StarStar(XoRoShiRo1024StarStar source)

next in interface RandomLongSourcepublic UniformRandomProvider jump()
The jump size is the equivalent of 2512
calls to nextLong(). It can provide
up to 2512 non-overlapping subsequences.
jump in interface JumpableUniformRandomProviderpublic JumpableUniformRandomProvider longJump()
The jump size is the equivalent of 2768 calls to
nextLong(). It can provide up to
2256 non-overlapping subsequences of length 2768; each
subsequence can provide up to 2256 non-overlapping subsequences of
length 2512 using the jump() method.
