CardinalityAggregationBuilder

public CardinalityAggregationBuilder(java.lang.String name,
                                     ValueType targetValueType)

CardinalityAggregationBuilder

public CardinalityAggregationBuilder(CardinalityAggregationBuilder clone,
                                     AggregatorFactories.Builder factoriesBuilder,
                                     java.util.Map<java.lang.String,java.lang.Object> metaData)

CardinalityAggregationBuilder

public CardinalityAggregationBuilder(StreamInput in)
                              throws java.io.IOException

Read from a stream.

Throws:

java.io.IOException

Method Detail

parse

public static AggregationBuilder parse(java.lang.String aggregationName,
                                       XContentParser parser)
                                throws java.io.IOException

Throws:

java.io.IOException

shallowCopy

protected AggregationBuilder shallowCopy(AggregatorFactories.Builder factoriesBuilder,
                                         java.util.Map<java.lang.String,java.lang.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 java.io.IOException

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<ValuesSource,CardinalityAggregationBuilder>

Throws:

java.io.IOException

serializeTargetValueType

protected boolean serializeTargetValueType()

Description copied from class: ValuesSourceAggregationBuilder

Should this builder serialize its targetValueType? Defaults to false. All subclasses that override this to true should use the three argument read constructor rather than the four argument version.

Overrides:

serializeTargetValueType in class ValuesSourceAggregationBuilder<ValuesSource,CardinalityAggregationBuilder>

precisionThreshold

public CardinalityAggregationBuilder precisionThreshold(long precisionThreshold)

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

precisionThreshold

public java.lang.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(SearchContext context,
                                                                                                ValuesSourceConfig<ValuesSource> config,

Throws:

java.io.IOException

doXContentBody

public XContentBuilder doXContentBody(XContentBuilder builder,
                                      ToXContent.Params params)
                               throws java.io.IOException

Specified by:
