  • Method Details

    • orderElements

      public java.util.List<BucketOrder> orderElements()
      unmodifiable list of BucketOrders to sort on.
    • toXContent

      public XContentBuilder toXContent​(XContentBuilder builder, ToXContent.Params params) throws
    • comparator

      public java.util.Comparator<MultiBucketsAggregation.Bucket> comparator​(Aggregator aggregator)
      Specified by:
      comparator in class BucketOrder
      A comparator for the bucket based on the given aggregator. The comparator is used in two phases:

      - aggregation phase, where each shard builds a list of buckets to be sent to the coordinating node. In this phase, the passed in aggregator will be the aggregator that aggregates the buckets on the shard level.

      - reduce phase, where the coordinating node gathers all the buckets from all the shards and reduces them to a final bucket list. In this case, the passed in aggregator will be null.
