Method Details

getLeafCollector

public LeafBucketCollector getLeafCollector(org.apache.lucene.index.LeafReaderContext ctx,
LeafBucketCollector sub)
                                     throws java.io.IOException

Description copied from class: AggregatorBase

Get a LeafBucketCollector for the given ctx, which should delegate to the given collector.

Specified by:

getLeafCollector in class AggregatorBase

Throws:

java.io.IOException

buildAggregations

public InternalAggregation[] buildAggregations(long[] owningBucketOrds)
                                        throws java.io.IOException

Description copied from class: Aggregator

Build the results of this aggregation.

Specified by:

buildAggregations in class Aggregator

Parameters:

owningBucketOrds - the ordinals of the buckets that we want to collect from this aggregation

Returns:

the results for each ordinal, in the same order as the array of ordinals

Throws:

java.io.IOException

buildEmptyAggregation

public InternalAggregation buildEmptyAggregation()

Description copied from class: Aggregator

Build an empty aggregation.

Specified by:

buildEmptyAggregation in class Aggregator

collectDebugInfo

public void collectDebugInfo(java.util.function.BiConsumer<java.lang.String,java.lang.Object> add)

Description copied from class: Aggregator

Collect debug information to add to the profiling results. This will only be called if the aggregation is being profiled.

Well behaved implementations will always call the superclass implementation just in case it has something interesting. They will also only add objects which can be serialized with StreamOutput.writeGenericValue(Object) and XContentBuilder.value(Object). And they'll have an integration test.

Overrides:

collectDebugInfo in class DeferableBucketAggregator

doClose

protected void doClose()

Description copied from class: AggregatorBase

Release instance-specific data.

Overrides:

doClose in class AggregatorBase

buildEmptyTermsAggregation

protected StringTerms buildEmptyTermsAggregation()

buildEmptySignificantTermsAggregation

protected SignificantStringTerms buildEmptySignificantTermsAggregation(long subsetSize,
SignificanceHeuristic significanceHeuristic)
