createInternal

public Aggregator createInternal(Aggregator parent,
 CardinalityUpperBound cardinality,
 Map<String,Object> metadata)
                          throws IOException

Specified by:

createInternal in class AggregatorFactory

Throws:

createUnmapped

protected abstract Aggregator createUnmapped(Aggregator parent,
 Map<String,Object> metadata)
                                      throws IOException

Create the Aggregator for a ValuesSource that doesn't have values.

Throws:

IOException

doCreateInternal

protected abstract Aggregator doCreateInternal(Aggregator parent,
 CardinalityUpperBound cardinality,
 Map<String,Object> metadata)
                                        throws IOException

Create the Aggregator for a ValuesSource that has values.

Parameters:

cardinality - Upper bound of the number of owningBucketOrds that the Aggregator created by this method will be asked to collect.

Throws:

IOException

getStatsSubtype

public String getStatsSubtype()

Description copied from class: AggregatorFactory

Returns the aggregation subtype for nodes usage stats.

It should match the types registered by calling AggregationUsageService. In other words, it should be ValueSourcesType for the VST aggregations OTHER_SUBTYPE for all other aggregations.

Overrides:
