Constructor Detail

InternalAggregations

public InternalAggregations(java.util.List<InternalAggregation> aggregations)

Constructs a new aggregation.

InternalAggregations

public InternalAggregations(java.util.List<InternalAggregation> aggregations,
                            java.util.List<SiblingPipelineAggregator> topLevelPipelineAggregators)

Constructs a new aggregation providing its InternalAggregations and SiblingPipelineAggregators

Method Detail

reduce

public static InternalAggregations reduce(java.util.List<InternalAggregations> aggregationsList,
                                          InternalAggregation.ReduceContext context)

Reduces the given list of aggregations as well as the top-level pipeline aggregators extracted from the first InternalAggregations object found in the list. Note that top-level pipeline aggregators are reduced only as part of the final reduction phase, otherwise they are left untouched.

reduce

public static InternalAggregations reduce(java.util.List<InternalAggregations> aggregationsList,
                                          java.util.List<SiblingPipelineAggregator> topLevelPipelineAggregators,
                                          InternalAggregation.ReduceContext context)

Reduces the given list of aggregations as well as the provided top-level pipeline aggregators. Note that top-level pipeline aggregators are reduced only as part of the final reduction phase, otherwise they are left untouched.
