java.lang.Object

org.elasticsearch.search.aggregations.support.AggregationContext

org.elasticsearch.search.aggregations.support.AggregationContext.ProductionAggregationContext

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, Releasable

Enclosing class:

AggregationContext

public static class AggregationContext.ProductionAggregationContext
extends AggregationContext

Implementation of AggregationContext for production usage that wraps our ubiquitous SearchExecutionContext and anything else specific to aggregations. Unit tests should generally avoid using this because it requires a huge portion of a real Elasticsearch node.
