Method Details
-
getWriteableName
Description copied from interface:NamedWriteableReturns the name of the writeable object- Specified by:
getWriteableNamein interfaceNamedWriteable
-
empty
public static InternalHDRPercentiles empty(String name, double[] keys, boolean keyed, DocValueFormat format, Map<String, Object> metadata) -
iterator
- Specified by:
iteratorin interfaceIterable<Percentile>
-
percentile
public double percentile(double percent) Description copied from interface:PercentilesReturn the value associated with the provided percentile.- Specified by:
percentilein interfacePercentiles
-
percentileAsString
Description copied from interface:PercentilesReturn the value associated with the provided percentile as a String.- Specified by:
percentileAsStringin interfacePercentiles
-
value
public double value(double key) -
createReduced
-
doWriteTo
- Specified by:
doWriteToin classInternalAggregation- Throws:
IOException
-
value
Description copied from interface:NumericMetricsAggregation.MultiValueReturn the result of 1 value by name- Specified by:
valuein interfaceNumericMetricsAggregation.MultiValue- Specified by:
valuein classInternalNumericMetricsAggregation.MultiValue- Parameters:
name- of the value- Returns:
- the value
-
valueNames
Description copied from interface:NumericMetricsAggregation.MultiValueReturn an iterable over all value names this multi value aggregation provides. The iterable might be created on the fly, if you need to call this multiple times, please cache the result in a variable on caller side..- Returns:
- iterable over all value names
-
formatter
-
getState
public org.HdrHistogram.DoubleHistogram getState()Return the internalDoubleHistogramsketch for this metric. -
getKeys
public double[] getKeys()Return the keys (percentiles) requested. -
keyed
public boolean keyed()Should the output be keyed. -
getLeaderReducer
Description copied from class:InternalAggregationReturn an object that Reduces several aggregations to a single one. This method is called whenInternalAggregation.canLeadReduction()returns true and expects an reducer that produces the right result.- Specified by:
getLeaderReducerin classInternalAggregation
-
finalizeSampling
Description copied from class:InternalAggregationCalled by the parent sampling context. Should only ever be called once as some aggregations scale their internal values- Overrides:
finalizeSamplingin classInternalAggregation- Parameters:
samplingContext- the current sampling context- Returns:
- new aggregation with the sampling context applied, could be the same aggregation instance if nothing needs to be done
-
doXContentBody
public XContentBuilder doXContentBody(XContentBuilder builder, ToXContent.Params params) throws IOException - Specified by:
doXContentBodyin classInternalAggregation- Throws:
IOException
