Method Details

createInternal

public Aggregator createInternal(SearchContext searchContext, Aggregator parent, CardinalityUpperBound cardinality, java.util.Map<java.lang.String,java.lang.Object> metadata) throws java.io.IOException

Specified by:

createInternal in class AggregatorFactory

Throws:

java.io.IOException

createUnmapped

protected abstract Aggregator createUnmapped(SearchContext searchContext, Aggregator parent, java.util.Map<java.lang.String,java.lang.Object> metadata) throws java.io.IOException

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

Throws:

java.io.IOException

doCreateInternal

protected abstract Aggregator doCreateInternal(SearchContext searchContext, Aggregator parent, CardinalityUpperBound cardinality, java.util.Map<java.lang.String,java.lang.Object> metadata) throws java.io.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:

java.io.IOException

getStatsSubtype

public java.lang.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:
