public class XorShift1024Star extends LongProvider implements JumpableUniformRandomProvider
XorShift1024* algorithm.
Note: This has been superseded by XorShift1024StarPhi. The sequences emitted
by both generators are correlated.

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 XorShift1024Star(long[] seed, long multiplier)

The jump size is the equivalent of 2512
calls to nextLong(). It can provide
up to 2512 non-overlapping subsequences.
