create
Description copied from class:InternalMultiBucketAggregation
Create a new copy of thisAggregation
with the same settings as thisAggregation
and contains the provided buckets.- Specified by:
create
in classInternalMultiBucketAggregation<InternalVariableWidthHistogram,
InternalVariableWidthHistogram.Bucket> - Parameters:
buckets
- the buckets to use in the newAggregation
- Returns:
- the new
Aggregation
-
