ThreadBarrier.BarrierTimer (server 6.6.0 API)

java.lang.Object
- org.elasticsearch.common.util.concurrent.ThreadBarrier.BarrierTimer

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

ThreadBarrier
```
public static class ThreadBarrier.BarrierTimer
extends java.lang.Object
implements java.lang.Runnable
```
A Barrier action to be used in conjunction with ThreadBarrier to measure performance between barrier awaits. This runnable will execute when the barrier is tripped. Make sure to reset() the timer before next Measurement.

See Also:

Usage example: BarrierTimer timer = new BarrierTimer(); ThreadBarrier barrier = new ThreadBarrier( nTHREADS + 1, timer ); .. barrier.await(); // starts timer when all threads trip on await barrier.await(); // stops timer when all threads trip on await .. long time = timer.getTimeInNanos(); long tpi = time / ((long)nREPEATS * nTHREADS); //throughput per thread iteration long secs = timer.getTimeInSeconds(); //total runtime in seconds .. timer.reset(); // reuse timer
