writeTo
public void writeTo(StreamOutput out) throws java.io.IOException
Description copied from interface:Writeable
Write this into the StreamOutput.
-
getTopLevelPipelineAggregators
public java.util.List<SiblingPipelineAggregator> getTopLevelPipelineAggregators()
Returns the top-level pipeline aggregators. Note that top-level pipeline aggregators become normal aggregation once the final reduction has been performed, after which they become part of the list ofInternalAggregation
s.
-
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 firstInternalAggregations
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.
