Constructor Details

ValueCountAggregationBuilder

public ValueCountAggregationBuilder(java.lang.String name)

ValueCountAggregationBuilder

protected ValueCountAggregationBuilder(ValueCountAggregationBuilder clone, AggregatorFactories.Builder factoriesBuilder, java.util.Map<java.lang.String,java.lang.Object> metadata)

ValueCountAggregationBuilder

public ValueCountAggregationBuilder(StreamInput in) throws java.io.IOException

Read from a stream.

Throws:

java.io.IOException

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<ValueCountAggregationBuilder>

Returns:

The CoreValuesSourceType we expect this script to yield.

shallowCopy

protected AggregationBuilder shallowCopy(AggregatorFactories.Builder factoriesBuilder, java.util.Map<java.lang.String,java.lang.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)

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<ValueCountAggregationBuilder>

serializeTargetValueType

protected boolean serializeTargetValueType(Version version)

Description copied from class: ValuesSourceAggregationBuilder

DO NOT OVERRIDE THIS! This method only exists for legacy support. No new aggregations need this, nor should they override it.

Overrides:

serializeTargetValueType in class ValuesSourceAggregationBuilder<ValueCountAggregationBuilder>

Parameters:

version - For backwards compatibility, subclasses can change behavior based on the version

innerBuild

protected org.elasticsearch.search.aggregations.metrics.ValueCountAggregatorFactory innerBuild(QueryShardContext queryShardContext, ValuesSourceConfig config, AggregatorFactory parent, AggregatorFactories.Builder subFactoriesBuilder) throws java.io.IOException

Specified by:

innerBuild in class ValuesSourceAggregationBuilder<ValueCountAggregationBuilder>

Throws:

java.io.IOException

doXContentBody

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

Specified by:

doXContentBody in class ValuesSourceAggregationBuilder<ValueCountAggregationBuilder>

Throws:

java.io.IOException

getType

public java.lang.String getType()

Description copied from interface: BaseAggregationBuilder

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