getWriteableName
Description copied from interface:NamedWriteable
Returns the name of the writeable object -
value
public double value() -
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
-
canLeadReduction
public boolean canLeadReduction()Description copied from class:InternalAggregation
Return true if this aggregation can lead a reduction (ie, is not unmapped or empty). If this agg returns false, it should return itself if asked to lead a reduction.- Overrides:
canLeadReduction
in classInternalAggregation
-
