InternalHDRPercentiles

public InternalHDRPercentiles(StreamInput in)
                       throws IOException

Read from a stream.

Throws:

IOException

Method Details

getWriteableName

public String getWriteableName()

Description copied from interface: NamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

iterator

public Iterator<Percentile> iterator()

Specified by:

iterator in interface Iterable<Percentile>

percentile

public double percentile(double percent)

Description copied from interface: Percentiles

Return the value associated with the provided percentile.

Specified by:

percentile in interface Percentiles

percentileAsString

public String percentileAsString(double percent)

Description copied from interface: Percentiles

Return the value associated with the provided percentile as a String.

Specified by:

percentileAsString in interface Percentiles

value

public double value(double key)

createReduced

protected org.elasticsearch.search.aggregations.metrics.AbstractInternalHDRPercentiles createReduced(String name,
 double[] keys,
 org.HdrHistogram.DoubleHistogram merged,
 boolean keyed,
 Map<String,Object> metadata)

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class InternalAggregation

Throws:

IOException

value

public double value(String name)

Description copied from interface: NumericMetricsAggregation.MultiValue

Return the result of 1 value by name

Specified by:

value in interface NumericMetricsAggregation.MultiValue

Specified by:

value in class InternalNumericMetricsAggregation.MultiValue

Parameters:

name - of the value

Returns:

the value

valueNames

public Iterable<String> valueNames()

Description copied from interface: NumericMetricsAggregation.MultiValue

Return 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

public DocValueFormat formatter()

getEstimatedMemoryFootprint

public long getEstimatedMemoryFootprint()

getState

public org.HdrHistogram.DoubleHistogram getState()

Return the internal DoubleHistogram sketch for this metric.

getKeys

public double[] getKeys()

Return the keys (percentiles) requested.

keyed

public boolean keyed()

Should the output be keyed.

reduce

public org.elasticsearch.search.aggregations.metrics.AbstractInternalHDRPercentiles reduce(List<InternalAggregation> aggregations,
 AggregationReduceContext reduceContext)

Description copied from class: InternalAggregation

Reduces the given aggregations to a single one and returns it. In most cases, the assumption will be the all given aggregations are of the same type (the same type as this aggregation). For best efficiency, when implementing, try reusing an existing instance (typically the first in the given list) to save on redundant object construction.

Specified by:

reduce in class InternalAggregation

See Also:

• InternalAggregation.mustReduceOnSingleInternalAgg()

finalizeSampling

public InternalAggregation finalizeSampling(SamplingContext samplingContext)

Description copied from class: InternalAggregation

Called by the parent sampling context. Should only ever be called once as some aggregations scale their internal values

Overrides:

finalizeSampling in class InternalAggregation

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 org.elasticsearch.xcontent.XContentBuilder doXContentBody(org.elasticsearch.xcontent.XContentBuilder builder,
 org.elasticsearch.xcontent.ToXContent.Params params)
                                                          throws IOException

Specified by:

doXContentBody in class InternalAggregation

Throws:

IOException

equals

public boolean equals(Object obj)

Overrides:

equals in class InternalNumericMetricsAggregation

hashCode

public int hashCode()

Overrides:

hashCode in class InternalNumericMetricsAggregation
