Examples of freenet.support.math.RunningAverage

freenet.support.math.RunningAverage
A running average. That is, something that takes reports as numbers and generates a current value. Synchronized class, including clone().

    // actually we’d want to convert uptime to seconds here but this is results in better accuracy.
    return getSentOverhead() * SECONDS.toMillis(1) / uptime;
  }


  public synchronized void successfulBlockReceive(boolean realTimeFlag, boolean isLocal) {
    RunningAverage blockTransferPSuccess = realTimeFlag ? blockTransferPSuccessRT : blockTransferPSuccessBulk;
    blockTransferPSuccess.report(1.0);
    if(isLocal)
      blockTransferPSuccessLocal.report(1.0);
    if(logMINOR) Logger.minor(this, "Successful receives: "+blockTransferPSuccess.currentValue()+" count="+blockTransferPSuccess.countReports()+" realtime="+realTimeFlag);
