Constructor Details

CardinalityAggregationBuilder

public CardinalityAggregationBuilder(String name)

CardinalityAggregationBuilder

public CardinalityAggregationBuilder(CardinalityAggregationBuilder clone,
 AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

CardinalityAggregationBuilder

public CardinalityAggregationBuilder(StreamInput in)
                              throws IOException

Read from a stream.

Throws:

IOException

Method Details

registerAggregators

public static void registerAggregators(ValuesSourceRegistry.Builder builder)

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<CardinalityAggregationBuilder>

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

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<CardinalityAggregationBuilder>

Throws:

IOException

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<CardinalityAggregationBuilder>

Parameters:

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

precisionThreshold

public CardinalityAggregationBuilder precisionThreshold(long precisionThreshold)

Set a precision threshold. Higher values improve accuracy but also increase memory usage.

precisionThreshold

public Long precisionThreshold()

Get the precision threshold. Higher values improve accuracy but also increase memory usage. Will return null if the precisionThreshold has not been set yet.

innerBuild

protected org.elasticsearch.search.aggregations.metrics.CardinalityAggregatorFactory innerBuild(AggregationContext context,
 ValuesSourceConfig config,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                                                                         throws IOException

Specified by:

innerBuild in class ValuesSourceAggregationBuilder<CardinalityAggregationBuilder>

Throws:

IOException

doXContentBody

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

Specified by:

doXContentBody in class ValuesSourceAggregationBuilder<CardinalityAggregationBuilder>

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class ValuesSourceAggregationBuilder<CardinalityAggregationBuilder>

equals

public boolean equals(Object obj)

Overrides:

equals in class ValuesSourceAggregationBuilder<CardinalityAggregationBuilder>

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<CardinalityAggregationBuilder>
