LXMBenchmark (Apache Commons RNG JMH Benchmark 1.7 API)

java.lang.Object
- org.apache.commons.rng.examples.jmh.core.LXMBenchmark

```
public class LXMBenchmark
extends Object
```
Executes a benchmark for operations used in the LXM family of RNGs.
Note

Some code in this benchmark is commented out. It requires a higher version of Java than the current target. Bumping the JMH module to a higher minimum java version prevents running benchmarks on the target JVM for the Commons RNG artifacts. Thus these benchmarks must be manually reinstated by uncommenting the code and updating the Java version in the module pom.
