Constructor Detail

### StatCalculator

    public StatCalculator()

Method Detail

### clear

    public void clear()

### addValue

    public void addValue(long newValue)

### addValue

    public void addValue(int newValue)

### addValue

    public void addValue(float newValue)

### addValue

    public void addValue(double newValue)

### addBytes

    public void addBytes(long newValue)

### addAll

    public void addAll(StatCalculator calc)

### getMedian

    public Number getMedian()

### getTotalBytes

    public long getTotalBytes()

### getPercentPoint

    public Number getPercentPoint(float percent)

  Get the value which %percent% of the values are less than. This works just like median (where median represents the 50% point). A typical desire is to see the 90% point - the value that 90% of the data points are below, the remaining 10% are above.

  Parameters:
    `percent` -
  Returns:
    number of values less than the percentage

### getPercentPoint

    public Number getPercentPoint(double percent)

  Get the value which %percent% of the values are less than. This works just like median (where median represents the 50% point). A typical desire is to see the 90% point - the value that 90% of the data points are below, the remaining 10% are above.

  Parameters:
    `percent` -
  Returns:
    number of values less than the percentage

### getDistribution

    public HashMap getDistribution()

  The method has a limit of 1% as the finest granularity. We do this to make sure we get a whole number for iterating.

### getMean

    public double getMean()

### getStandardDeviation

    public double getStandardDeviation()

### getMin

    public Number getMin()

### getMax

    public Number getMax()

### getCount

    public int getCount()

### addValue

    public void addValue(Number val)
