getWriteableName
Description copied from interface:NamedWriteable
Returns the name of the writeable object- Specified by:
getWriteableName
in interfaceNamedWriteable
-
getType
- Specified by:
getType
in interfaceAggregation
- Overrides:
getType
in classInternalAggregation
- Returns:
- a string representing the type of the aggregation. This type is added to the aggregation name in the response, so that it can later be used by clients to determine type of the aggregation and parse it into the proper object.
-
newAggregation
protected InternalSingleBucketAggregation newAggregation(String name, long docCount, InternalAggregations subAggregations) Description copied from class:InternalSingleBucketAggregation
Create a new empty sub aggregation. This must be a new instance on each call.- Specified by:
newAggregation
in classInternalSingleBucketAggregation
-
reduce
public InternalAggregation reduce(List<InternalAggregation> aggregations, AggregationReduceContext 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
