Constructor Details

StatsAggregationBuilder

public StatsAggregationBuilder(String name)

StatsAggregationBuilder

protected StatsAggregationBuilder(StatsAggregationBuilder clone,
 AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

StatsAggregationBuilder

public StatsAggregationBuilder(StreamInput in)
                        throws IOException

Read from a stream.

Throws:

IOException

Method Details

registerAggregators

public static void registerAggregators(ValuesSourceRegistry.Builder builder)

shallowCopy

protected AggregationBuilder shallowCopy(AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

Description copied from class: AggregationBuilder

Create a shallow copy of this builder and replacing AggregationBuilder.factoriesBuilder and metadata. Used by AggregationBuilder.rewrite(QueryRewriteContext).

Specified by:

shallowCopy in class AggregationBuilder

defaultValueSourceType

protected ValuesSourceType defaultValueSourceType()

Description copied from class: ValuesSourceAggregationBuilder

Aggregations should use this method to define a ValuesSourceType of last resort. This will only be used when the resolver can't find a field and the user hasn't provided a value type hint.

Specified by:

defaultValueSourceType in class ValuesSourceAggregationBuilder<StatsAggregationBuilder>

Returns:

The CoreValuesSourceType we expect this script to yield.

innerWriteTo

protected void innerWriteTo(StreamOutput out)

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<StatsAggregationBuilder>

innerBuild

protected org.elasticsearch.search.aggregations.metrics.StatsAggregatorFactory innerBuild(AggregationContext context,
 ValuesSourceConfig config,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                                                                   throws IOException

Specified by:

innerBuild in class ValuesSourceAggregationBuilder<StatsAggregationBuilder>

Throws:

IOException

doXContentBody

public org.elasticsearch.common.xcontent.XContentBuilder doXContentBody(org.elasticsearch.common.xcontent.XContentBuilder builder,
 org.elasticsearch.common.xcontent.ToXContent.Params params)
                                                                 throws IOException

Specified by:

doXContentBody in class ValuesSourceAggregationBuilder<StatsAggregationBuilder>

Throws:

IOException

getType

public String getType()

Description copied from interface: BaseAggregationBuilder

The name of the type of aggregation built by this builder.

getRegistryKey

protected ValuesSourceRegistry.RegistryKey<?> getRegistryKey()

Specified by:

getRegistryKey in class ValuesSourceAggregationBuilder<StatsAggregationBuilder>

getOutputFieldNames

public Optional<Set<String>> getOutputFieldNames()

Description copied from class: AggregationBuilder

Return the field names this aggregation creates. This method is a optional helper for clients that need to know the output field names.

Overrides:

getOutputFieldNames in class AggregationBuilder

Returns:

The set of output field names this aggregation produces or Optional.empty() if not implemented or Optional.of(emptySet()) if the fields are not known.
