Constructor Details

PipelineAggregationBuilder

protected PipelineAggregationBuilder(String name,
 String[] bucketsPaths)

Constructs a new pipeline aggregator factory.

Parameters:

name - The aggregation name

Method Details

getName

public String getName()

Return this aggregation's name.

getBucketsPaths

public final String[] getBucketsPaths()

Return the consumed buckets paths.

validate

protected abstract void validate(PipelineAggregationBuilder.ValidationContext context)

Makes sure this builder is properly configured.

create

protected abstract PipelineAggregator create()

Creates the pipeline aggregator

Returns:

The created aggregator

setMetadata

public abstract PipelineAggregationBuilder setMetadata(Map<String,Object> metadata)

Associate metadata with this PipelineAggregationBuilder.

Specified by:

setMetadata in interface BaseAggregationBuilder

subAggregations

public PipelineAggregationBuilder subAggregations(AggregatorFactories.Builder subFactories)

Description copied from interface: BaseAggregationBuilder

Set the sub aggregations if this aggregation supports sub aggregations. Returns this for chaining.

Specified by:

subAggregations in interface BaseAggregationBuilder

toString

public String toString()

Overrides:

toString in class Object

rewrite

public PipelineAggregationBuilder rewrite(QueryRewriteContext context)
                                   throws IOException

Rewrites this instance based on the provided context. The returned objects will be the same instance as this if no changes during the rewrite were applied.

The default implementation return the same instance. It should be overridden by aggregations that must load data before they can be run, particularly if that load must by asynchronous.

Specified by:

rewrite in interface Rewriteable<PipelineAggregationBuilder>

Throws:

IOException
