Class TopMetricsAggregationBuilder

java.lang.Object

org.elasticsearch.search.aggregations.AggregationBuilder

org.elasticsearch.search.aggregations.AbstractAggregationBuilder<TopMetricsAggregationBuilder>

org.elasticsearch.client.analytics.TopMetricsAggregationBuilder

All Implemented Interfaces:

NamedWriteable, Writeable, Rewriteable<AggregationBuilder>, BaseAggregationBuilder, org.elasticsearch.xcontent.ToXContent, org.elasticsearch.xcontent.ToXContentFragment

public class TopMetricsAggregationBuilder
extends AbstractAggregationBuilder<TopMetricsAggregationBuilder>

Builds the Top Metrics aggregation request.

NOTE: This extends AbstractAggregationBuilder for compatibility with SearchSourceBuilder.aggregation(AggregationBuilder) but it doesn't support any "server" side things like Writeable.writeTo(StreamOutput), AggregationBuilder.rewrite(QueryRewriteContext), or AbstractAggregationBuilder.build(AggregationContext, AggregatorFactory).
