Constructor Details

ScriptedMetricAggregationBuilder

public ScriptedMetricAggregationBuilder(String name)

ScriptedMetricAggregationBuilder

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

ScriptedMetricAggregationBuilder

public ScriptedMetricAggregationBuilder(StreamInput in)
                                 throws IOException

Read from a stream.

Throws:

IOException

Method Details

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.

Specified by:

shallowCopy in class AggregationBuilder

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class AbstractAggregationBuilder<ScriptedMetricAggregationBuilder>

Throws:

IOException

supportsSampling

public boolean supportsSampling()

Description copied from class: AggregationBuilder

Does this aggregation support running with in a sampling context. By default, it's false for all aggregations. If the sub-classed builder supports sampling, be sure of the following that the resulting internal aggregation objects override the InternalAggregation.finalizeSampling(SamplingContext) and scales any values that require scaling.

Overrides:

supportsSampling in class AggregationBuilder

Returns:

does this aggregation builder support sampling

initScript

public ScriptedMetricAggregationBuilder initScript(Script initScript)

Set the init script.

mapScript

public ScriptedMetricAggregationBuilder mapScript(Script mapScript)

Set the map script.

combineScript

public ScriptedMetricAggregationBuilder combineScript(Script combineScript)

Set the combine script.

reduceScript

public ScriptedMetricAggregationBuilder reduceScript(Script reduceScript)

Set the reduce script.

params

public ScriptedMetricAggregationBuilder params(Map<String,Object> params)

Set parameters that will be available in the init, map and combine phases.

bucketCardinality

public AggregationBuilder.BucketCardinality bucketCardinality()

Description copied from class: AggregationBuilder

A rough count of the number of buckets that Aggregators built by this builder will contain per owning parent bucket.

Specified by:

bucketCardinality in class AggregationBuilder

doBuild

protected org.elasticsearch.search.aggregations.metrics.ScriptedMetricAggregatorFactory doBuild(AggregationContext context,
 AggregatorFactory parent,
 AggregatorFactories.Builder subfactoriesBuilder)
                                                                                         throws IOException

Specified by:

doBuild in class AbstractAggregationBuilder<ScriptedMetricAggregationBuilder>

Throws:

IOException

internalXContent

protected XContentBuilder internalXContent(XContentBuilder builder,
 ToXContent.Params builderParams)
                                    throws IOException

Specified by:

internalXContent in class AbstractAggregationBuilder<ScriptedMetricAggregationBuilder>

Throws:

IOException

Description copied from interface: VersionedNamedWriteable

The minimal version of the recipient this object can be sent to

hashCode

public int hashCode()

Overrides:
