getWriteableName
public java.lang.String getWriteableName()Description copied from interface:NamedWriteable
Returns the name of the writeable object- Specified by:
getWriteableName
in interfaceNamedWriteable
- Overrides:
getWriteableName
in classInternalSampler
-
reduce
public InternalAggregation reduce(java.util.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.- Overrides:
reduce
in classInternalSingleBucketAggregation
-
isMapped
public boolean isMapped()Description copied from class:InternalAggregation
Return true if this aggregation is mapped, and can lead a reduction. If this agg returns false, it should return itself if asked to lead a reduction- Overrides:
isMapped
in classInternalAggregation
