Constructor Details

RareTermsAggregationBuilder

public RareTermsAggregationBuilder(String name)

RareTermsAggregationBuilder

public RareTermsAggregationBuilder(StreamInput in)
                            throws IOException

Read from a stream.

Throws:

IOException

Method Details

registerAggregators

public static void registerAggregators(ValuesSourceRegistry.Builder builder)

supportsSampling

public boolean supportsSampling()

Description copied from class: AggregationBuilder

Does this aggregation support running with in a sampling context. By default, it's false for all aggregations. If the sub-classed builder supports sampling, be sure of the following that the resulting internal aggregation objects override the InternalAggregation.finalizeSampling(SamplingContext) and scales any values that require scaling.

Overrides:

supportsSampling in class AggregationBuilder

Returns:

does this aggregation builder support sampling

defaultValueSourceType

protected ValuesSourceType defaultValueSourceType()

Description copied from class: ValuesSourceAggregationBuilder

Aggregations should use this method to define a ValuesSourceType of last resort. This will only be used when the resolver can't find a field and the user hasn't provided a value type hint.

Specified by:

defaultValueSourceType in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

Returns:

The CoreValuesSourceType we expect this script to yield.

shallowCopy

protected AggregationBuilder shallowCopy(AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

Description copied from class: AggregationBuilder

Create a shallow copy of this builder and replacing AggregationBuilder.factoriesBuilder and metadata. Used by AggregationBuilder.rewrite(QueryRewriteContext).

Specified by:

shallowCopy in class AggregationBuilder

serializeTargetValueType

protected boolean serializeTargetValueType(Version version)

Description copied from class: ValuesSourceAggregationBuilder

DO NOT OVERRIDE THIS!

This method only exists for legacy support. No new aggregations need this, nor should they override it.

Overrides:

serializeTargetValueType in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

Parameters:

version - For backwards compatibility, subclasses can change behavior based on the version

innerWriteTo

protected void innerWriteTo(StreamOutput out)
                     throws IOException

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

Throws:

IOException

maxDocCount

public RareTermsAggregationBuilder maxDocCount(long maxDocCount)

Set the maximum document count terms should have in order to appear in the response.

includeExclude

public RareTermsAggregationBuilder includeExclude(IncludeExclude includeExclude)

Set terms to include and exclude from the aggregation results

includeExclude

public IncludeExclude includeExclude()

Get terms to include and exclude from the aggregation results

getPrecision

public double getPrecision()

Get the current false positive rate for individual cuckoo filters.

setPrecision

public void setPrecision(double precision)

Set's the false-positive rate for individual cuckoo filters. Does not dictate the overall fpp rate since we use a "scaling" cuckoo filter which adds more filters as required, and the overall error rate grows differently than individual filters This value does, however, affect the overall space usage of the filter. Coarser precisions provide more compact filters. The default is 0.01

bucketCardinality

public AggregationBuilder.BucketCardinality bucketCardinality()

Description copied from class: AggregationBuilder

A rough count of the number of buckets that Aggregators built by this builder will contain per owning parent bucket.

Specified by:

bucketCardinality in class AggregationBuilder

innerBuild

protected ValuesSourceAggregatorFactory innerBuild(AggregationContext context,
 ValuesSourceConfig config,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                            throws IOException

Specified by:

innerBuild in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

Throws:

IOException

doXContentBody

protected XContentBuilder doXContentBody(XContentBuilder builder,
 ToXContent.Params params)
                                  throws IOException

Specified by:

doXContentBody in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

equals

public boolean equals(Object obj)

Overrides:

equals in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

getType

public String getType()

Description copied from interface: BaseAggregationBuilder

The name of the type of aggregation built by this builder.

getRegistryKey

protected ValuesSourceRegistry.RegistryKey<?> getRegistryKey()

Specified by:

getRegistryKey in class ValuesSourceAggregationBuilder<RareTermsAggregationBuilder>

getMinimalSupportedVersion

public Version getMinimalSupportedVersion()

Description copied from interface: VersionedNamedWriteable

The minimal version of the recipient this object can be sent to
