Class MultiValuesSourceAggregationBuilder<AB extends MultiValuesSourceAggregationBuilder<AB>>

java.lang.Object

org.elasticsearch.search.aggregations.AggregationBuilder

org.elasticsearch.search.aggregations.AbstractAggregationBuilder<AB>

org.elasticsearch.search.aggregations.support.MultiValuesSourceAggregationBuilder<AB>

All Implemented Interfaces:

NamedWriteable, Writeable, Rewriteable<AggregationBuilder>, BaseAggregationBuilder, ToXContent, ToXContentFragment

Direct Known Subclasses:

MultiValuesSourceAggregationBuilder.LeafOnly

public abstract class MultiValuesSourceAggregationBuilder<AB extends MultiValuesSourceAggregationBuilder<AB>>
extends AbstractAggregationBuilder<AB>

Similar to ValuesSourceAggregationBuilder, except it references multiple ValuesSources (e.g. so that an aggregation can pull values from multiple fields). A limitation of this class is that all the ValuesSource's being refereenced must be of the same type.

Constructor Details

MultiValuesSourceAggregationBuilder

protected MultiValuesSourceAggregationBuilder(String name)

MultiValuesSourceAggregationBuilder

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

MultiValuesSourceAggregationBuilder

protected MultiValuesSourceAggregationBuilder(StreamInput in)
                                       throws IOException

Read from a stream.

Throws:

IOException

Method Details

doWriteTo

protected final void doWriteTo(StreamOutput out)
                        throws IOException

Specified by:

doWriteTo in class AbstractAggregationBuilder<AB extends MultiValuesSourceAggregationBuilder<AB>>

Throws:

IOException

innerWriteTo

protected abstract void innerWriteTo(StreamOutput out)
                              throws IOException

Write subclass' state to the stream

Throws:

IOException

field

protected AB field(String propertyName,
 MultiValuesSourceFieldConfig config)

userValueTypeHint

public AB userValueTypeHint(ValueType valueType)

Sets the ValueType for the value produced by this aggregation

format

public AB format(String format)

Sets the format to use for the output of the aggregation.

defaultValueSourceType

protected abstract ValuesSourceType defaultValueSourceType()

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.

Returns:

The CoreValuesSourceType we expect this script to yield.

doBuild

protected final MultiValuesSourceAggregatorFactory doBuild(AggregationContext context,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                                    throws IOException

Specified by:

doBuild in class AbstractAggregationBuilder<AB extends MultiValuesSourceAggregationBuilder<AB>>

Throws:

IOException

resolveFormat

public static DocValueFormat resolveFormat(@Nullable
 String format,
 @Nullable
 ValueType valueType,
 ValuesSourceType defaultValuesSourceType)

innerBuild

protected abstract MultiValuesSourceAggregatorFactory innerBuild(AggregationContext context,
 Map<String,ValuesSourceConfig> configs,
 Map<String,QueryBuilder> filters,
 DocValueFormat format,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                                          throws IOException

Throws:

IOException

internalXContent

Specified by:

internalXContent in class AbstractAggregationBuilder<AB extends MultiValuesSourceAggregationBuilder<AB>>

Throws:

IOException

doXContentBody

protected abstract XContentBuilder doXContentBody(XContentBuilder builder,
 ToXContent.Params params)
                                           throws IOException

Throws:

IOException
