Method Details

registerAggregators

public static void registerAggregators(ValuesSourceRegistry.Builder builder)

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<DiversifiedAggregationBuilder>

Returns:

The CoreValuesSourceType we expect this script to yield.

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

innerWriteTo

protected void innerWriteTo(StreamOutput out)
                     throws IOException

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<DiversifiedAggregationBuilder>

Throws:

IOException

shardSize

public DiversifiedAggregationBuilder shardSize(int shardSize)

Set the max num docs to be returned from each shard.

shardSize

public int shardSize()

Get the max num docs to be returned from each shard.

maxDocsPerValue

public DiversifiedAggregationBuilder maxDocsPerValue(int maxDocsPerValue)

Set the max num docs to be returned per value.

maxDocsPerValue

public int maxDocsPerValue()
