getScale
public int getScale()
Description copied from interface:ExponentialHistogramPointData
Scale characterises the resolution of the histogram, with larger values of scale offering greater precision. Bucket boundaries of the histogram are located at integer powers of the base, wherebase = Math.pow(2, Math.pow(2, -scale))
.- Specified by:
getScale
in interfaceExponentialHistogramPointData
- Returns:
- the scale.
-
getSum
public double getSum()
Description copied from interface:ExponentialHistogramPointData
Returns the sum of all measurements in the data point. The sum should be disregarded if there are both positive and negative measurements.- Specified by:
getSum
in interfaceExponentialHistogramPointData
- Returns:
- the sum of all measurements in this data point.
-
getCount
public long getCount()
Description copied from interface:ExponentialHistogramPointData
Returns the number of measurements taken for this data point, including the positive bucket counts, negative bucket counts, and the zero count.- Specified by:
getCount
in interfaceExponentialHistogramPointData
- Returns:
- the number of measurements in this data point.
-
getZeroCount
public long getZeroCount()
Description copied from interface:ExponentialHistogramPointData
Returns the number of measurements equal to zero in this data point.- Specified by:
getZeroCount
in interfaceExponentialHistogramPointData
- Returns:
- the number of values equal to zero.
-
hasMin
public boolean hasMin()
Description copied from interface:ExponentialHistogramPointData
Returntrue
ifExponentialHistogramPointData.getMin()
is set.- Specified by:
hasMin
in interfaceExponentialHistogramPointData
-
getMin
public double getMin()
Description copied from interface:ExponentialHistogramPointData
The min of all measurements recorded, ifExponentialHistogramPointData.hasMin()
istrue
. IfExponentialHistogramPointData.hasMin()
isfalse
, the response should be ignored.- Specified by:
getMin
in interfaceExponentialHistogramPointData
-
hasMax
public boolean hasMax()
Description copied from interface:ExponentialHistogramPointData
Returntrue
ifExponentialHistogramPointData.getMax()
is set.- Specified by:
hasMax
in interfaceExponentialHistogramPointData
-
getMax
public double getMax()
Description copied from interface:ExponentialHistogramPointData
The max of all measurements recorded, ifExponentialHistogramPointData.hasMax()
istrue
. IfExponentialHistogramPointData.hasMax()
isfalse
, the response should be ignored.- Specified by:
getMax
in interfaceExponentialHistogramPointData
-
getPositiveBuckets
public ExponentialHistogramBuckets getPositiveBuckets()
Description copied from interface:ExponentialHistogramPointData
Return theExponentialHistogramBuckets
representing the positive measurements taken for this histogram.- Specified by:
getPositiveBuckets
in interfaceExponentialHistogramPointData
- Returns:
- the positive buckets.
-
getNegativeBuckets
public ExponentialHistogramBuckets getNegativeBuckets()
Description copied from interface:ExponentialHistogramPointData
Return theExponentialHistogramBuckets
