reduce
Description copied from class:InternalAggregation
Reduces the given aggregations to a single one and returns it. In most cases, the assumption will be the all given aggregations are of the same type (the same type as this aggregation). For best efficiency, when implementing, try reusing an existing instance (typically the first in the given list) to save on redundant object construction.- Specified by:
reduce
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
