Package org.elasticsearch.search.aggregations

Interface Summary

Interface	Description
Aggregation	An aggregation
Aggregations	Represents a set of computed addAggregation.
AggregationStreams.Stream	A stream that knows how to read an aggregation from the input.
Aggregator.Parser	Parses the aggregation request and creates the appropriate aggregator factory for it.
BucketCollector.BucketAnalysisCollector	Used to gather a summary from a bucket
HasAggregations

Class Summary

Class	Description
AbstractAggregationBuilder	Base structure for aggregation builders.
AggregationBinaryParseElement
AggregationBuilder<B extends AggregationBuilder<B>>	A base class for all bucket aggregation builders.
AggregationBuilders	Utility class to create aggregations.
AggregationModule	The main module for the get (binding all get components together)
AggregationParseElement	The search parse element that is responsible for parsing the get part of the request.
AggregationPhase
AggregationPhase.AggregationsCollector
AggregationStreams	A registry for all the dedicated streams in the aggregation module.
Aggregator
AggregatorFactories
AggregatorFactories.Builder
AggregatorFactory	A factory that knows how to create an Aggregator of a specific type.
AggregatorParsers	A registry for all the aggregator parser, also servers as the main parser for the aggregations module
BucketCollector	A Collector that can collect data in separate buckets.
FilteringBucketCollector	Filters a collection stream of docIds and related buckets using a sorted list of valid bucket ordinals.
InternalAggregation	An internal implementation of Aggregation.
InternalAggregation.CommonFields	Common xcontent fields that are shared among addAggregation
InternalAggregation.ReduceContext
InternalAggregation.Type	The aggregation type that holds all the string types that are associated with an aggregation: name - used as the parser type stream - used as the stream type
InternalAggregations	An internal implementation of Aggregations.
NonCollectingAggregator	An aggregator that is not collected, this can typically be used when running an aggregation over a field that doesn't have a mapping.
RecordingBucketCollector	Abstraction for implementations that record a "collect" stream for subsequent play-back
RecordingPerReaderBucketCollector	Records a "collect" stream for subsequent play-back using a per-segment object to collect matches.
SearchContextAggregations	The aggregation context that is part of the search context.
TransportAggregationModule	A module that registers all the transport streams for the addAggregation
ValuesSourceAggregationBuilder<B extends ValuesSourceAggregationBuilder<B>>	A base class for all bucket aggregation builders that are based on values (either script generated or field data values)

Enum Summary

Enum	Description
Aggregator.BucketAggregationMode	Defines the nature of the aggregator's aggregation execution when nested in other aggregators and the buckets they create.
Aggregator.SubAggCollectionMode

Exception Summary

Exception	Description
AggregationExecutionException	Thrown when failing to execute an aggregation
AggregationInitializationException	Thrown when failing to execute an aggregation
