SamplingStatCalculator (Apache JMeter dist API)

java.lang.Object
- org.apache.jmeter.visualizers.SamplingStatCalculator

Direct Known Subclasses:

CachingStatCalculator
```
public class SamplingStatCalculator
extends Object
```
Aggregate sample data container. Just instantiate a new instance of this class, and then call addSample(SampleResult) a few times, and pull the stats out with whatever methods you prefer.

- Constructor Detail
  - SamplingStatCalculator
```
public SamplingStatCalculator()
```
  - SamplingStatCalculator
```
public SamplingStatCalculator(String label)
```
- Method Detail
  - clear
```
public void clear()
```
    Clear the counters (useful for differential stats)
  - getCurrentSample
```
public Sample getCurrentSample()
```
  - getElapsed
```
public long getElapsed()
```
    Get the elapsed time for the samples
    
    Returns:
    
    how long the samples took
  - getRate
```
public double getRate()
```
    Returns the throughput associated to this sampler in requests per second. May be slightly skewed because it takes the timestamps of the first and last samples as the total time passed, and the test may actually have started before that start time and ended after that end time.
    
    Returns:
    
    throughput associated with this sampler per second
  - getBytesPerSecond
```
public double getBytesPerSecond()
```
    Throughput in bytes / second
    
    Returns:
    
    throughput in bytes/second
  - getKBPerSecond
```
public double getKBPerSecond()
```
    Throughput in kilobytes / second
    
    Returns:
    
    Throughput in kilobytes / second
  - getSentBytesPerSecond
```
public double getSentBytesPerSecond()
```
    Sent Throughput in bytes / second
    
    Returns:
    
    sent throughput in bytes/second
  - getSentKBPerSecond
```
public double getSentKBPerSecond()
```
    Sent Throughput in kilobytes / second
    
    Returns:
    
    Sent Throughput in kilobytes / second
  - getAvgPageBytes
```
public double getAvgPageBytes()
```
    calculates the average page size, which means divide the bytes by number of samples.
    
    Returns:
    
    average page size in bytes (0 if sample count is zero)
  - getLabel
```
public String getLabel()
```
    Returns:
    
    the label of this component
  - addSample
```
public Sample addSample(SampleResult res)
```
    Records a sample.
    
    Parameters:
    
    res - the sample to record
    
    Returns:
    
    newly created sample with current statistics
  - getErrorPercentage
```
public double getErrorPercentage()
```
    Returns the raw double value of the percentage of samples with errors that were recorded. (Between 0.0 and 1.0)
    
    Returns:
    
    the raw double value of the percentage of samples with errors that were recorded.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - getErrorCount
```
public long getErrorCount()
```
    Returns:
    
    errorCount
  - getMaxThroughput
```

```
public Number getPercentPoint(double percent)
```
  - getCount
```
public long getCount()
```

```
public Number getMax()
```
  - getMean
```
public double getMean()
```
  - getMeanAsNumber
```
public Number getMeanAsNumber()
```
  - getMedian
```
public Number getMedian()
```
  - getMin
