value
in interfaceNumericMetricsAggregation.MultiValue
- Specified by:
value
in classInternalNumericMetricsAggregation.MultiValue
- Parameters:
name
- of the value- Returns:
- the value
-
valueNames
Description copied from interface:NumericMetricsAggregation.MultiValue
Return an iterable over all value names this multi value aggregation provides. The iterable might be created on the fly, if you need to call this multiple times, please cache the result in a variable on caller side..- Specified by:
valueNames

-
getLeaderReducer
Description copied from class:InternalAggregation
Return 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.- Specified by:
getLeaderReducer
in classInternalAggregation
-
finalizeSampling
Description copied from class:InternalAggregation
Called by the parent sampling context. Should only ever be called once as some aggregations scale their internal values- Overrides:
finalizeSampling
in classInternalAggregation
- Parameters:
samplingContext
- the current sampling context- Returns:
- new aggregation with the sampling context applied, could be the same aggregation instance if nothing needs to be done
