## Class JProf

- java.lang.Object
- - org.cpsolver.ifs.util.JProf

-     public class JProf
      extends Object

  CPU time measurement. JAVA profiling extension is used. Java needs to be executed with -Xrunjprof. When the java is executed outside this profiler, `System.currentTimeMillis()` is used. Using `ThreadMXBean` to get the current thread CPU time, if supported. Using `System.nanoTime()` otherwise.
