メソッドの詳細

doReduce

public final InternalAggregation doReduce(Aggregations aggregations,
                                          InternalAggregation.ReduceContext context)

定義:

doReduce クラス内 SiblingPipelineAggregator

preCollection

protected void preCollection()

Called before initial collection and between successive collection runs. A chance to initialize or re-initialize state

buildAggregation

protected abstract InternalAggregation buildAggregation(List<PipelineAggregator> pipelineAggregators,
                                                        Map<String,Object> metadata)

Called after a collection run is finished to build the aggregation for the collected state.

パラメータ:

pipelineAggregators - the pipeline aggregators to add to the resulting aggregation

metadata - the metadata to add to the resulting aggregation

collectBucketValue

protected abstract void collectBucketValue(String bucketKey,
                                           Double bucketValue)

Called for each bucket with a value so the state can be modified based on the key and metric value for this bucket

パラメータ:

bucketKey - the key for this bucket as a String

bucketValue - the value of the metric specified in bucketsPath for this bucket
