public Iterable<String> 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..

reduce

public InternalStats reduce(List<InternalAggregation> aggregations,
 InternalAggregation.ReduceContext reduceContext)

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 class InternalAggregation
