getLeaderReducer
Description copied from class:InternalAggregationReturn an object that Reduces several aggregations to a single one. This method is called whenInternalAggregation.canLeadReduction()returns true and expects an reducer that produces the right result.- Overrides:
getLeaderReducerin classInternalSingleBucketAggregation
-
canLeadReduction
public boolean canLeadReduction()Description copied from class:InternalAggregationReturn true if this aggregation can lead a reduction (ie, is not unmapped or empty). If this agg returns false, it should return itself if asked to lead a reduction.- Overrides:
