public class XoRoShiRo1024Star extends AbstractXoRoShiRo1024
A large-state 64-bit generator suitable fordouble
generation. This is slightly faster than the all-purpose generatorXoRoShiRo1024PlusPlus
.This is a member of the Xor-Shift-Rotate family of generators. Memory footprint is 1024 bits and the period is 21024-1.

XoRoShiRo1024Star
public XoRoShiRo1024Star(long[] seed)
Creates a new instance.- Parameters:
seed
- Initial seed. 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.

XoRoShiRo1024Star
protected XoRoShiRo1024Star(XoRoShiRo1024Star source)
Creates a copy instance.- Parameters:
source
- Source to copy.
