Method Detail

collect

public void collect(int doc,
                    long owningBucketOrdinal)
             throws IOException

Description copied from class: BucketCollector

Called during the query phase, to collect & aggregate the given document.

Overrides:

collect in class GlobalOrdinalsStringTermsAggregator

owningBucketOrdinal - The ordinal of the bucket this aggregator belongs to, assuming this aggregator is not a top level aggregator. Typically, aggregators with #bucketAggregationMode set to Aggregator.BucketAggregationMode.MULTI_BUCKETS will heavily depend on this ordinal. Other aggregators may or may not use it and can see this ordinal as just an extra information for the aggregation context. For top level aggregators, the ordinal will always be equal to 0.

Throws:

IOException

buildAggregation

public SignificantStringTerms buildAggregation(long owningBucketOrdinal)

Overrides:

buildAggregation in class GlobalOrdinalsStringTermsAggregator

Returns:

The aggregated & built aggregation

buildEmptyAggregation

public SignificantStringTerms buildEmptyAggregation()

doClose

protected void doClose()

Description copied from class: Aggregator

Release instance-specific data.

Overrides:

doClose in class Aggregator
