XORShiftRandom (Flink : Core 2.0.0 API)

java.lang.Object
- java.util.Random
- - org.apache.flink.util.XORShiftRandom

All Implemented Interfaces:

Serializable
```
@Public
public class XORShiftRandom
extends Random
```
Implement a random number generator based on the XORShift algorithm discovered by George Marsaglia. This RNG is observed 4.5 times faster than Random in benchmark, with the cost that abandon thread-safety. So it's recommended to create a new XORShiftRandom for each thread.
