Class BucketSortPipelineAggregationBuilder

java.lang.Object

org.elasticsearch.search.aggregations.PipelineAggregationBuilder

org.elasticsearch.search.aggregations.pipeline.AbstractPipelineAggregationBuilder<BucketSortPipelineAggregationBuilder>

org.elasticsearch.search.aggregations.pipeline.BucketSortPipelineAggregationBuilder

All Implemented Interfaces:

NamedWriteable, Writeable, Rewriteable<PipelineAggregationBuilder>, BaseAggregationBuilder, ToXContent, ToXContentFragment

public class BucketSortPipelineAggregationBuilder
extends AbstractPipelineAggregationBuilder<BucketSortPipelineAggregationBuilder>

Builds a pipeline aggregation that allows sorting the buckets of its parent aggregation. The bucket _key, _count or sub-aggregations may be used as sort keys. Parameters from and size may also be set in order to truncate the result bucket list.
