doWriteTo
- Overrides:
doWriteToin classInternalSingleBucketAggregation- Throws:
IOException
-
getWriteableName
Description copied from interface:NamedWriteableReturns the name of the writeable object -
getType
- Specified by:
getTypein interfaceAggregation- Overrides:
getTypein classInternalAggregation- Returns:
- a string representing the type of the aggregation. This type is added to the aggregation name in the response, so that it can later be used by clients to determine type of the aggregation and parse it into the proper object.

newAggregation
protected InternalSingleBucketAggregation newAggregation(String name, long docCount, InternalAggregations subAggregations) Description copied from class:InternalSingleBucketAggregationCreate a new empty sub aggregation. This must be a new instance on each call.- Specified by:
newAggregationin classInternalSingleBucketAggregation
-
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:
