Constructor Detail

AggregationBuilder

protected AggregationBuilder(java.lang.String name)

Constructs a new aggregation builder.

Parameters:

name - The aggregation name

AggregationBuilder

protected AggregationBuilder(AggregationBuilder clone,
                             AggregatorFactories.Builder factoriesBuilder)

Method Detail

getName

public java.lang.String getName()

Return this aggregation's name.

build

protected abstract AggregatorFactory<?> build(SearchContext context,
                                              AggregatorFactory<?> parent)
                                       throws java.io.IOException

Internal: build an AggregatorFactory based on the configuration of this builder.

Throws:

java.io.IOException

setMetaData

public abstract AggregationBuilder setMetaData(java.util.Map<java.lang.String,java.lang.Object> metaData)

Associate metadata with this AggregationBuilder.

Specified by:

setMetaData in interface BaseAggregationBuilder

getMetaData

public abstract java.util.Map<java.lang.String,java.lang.Object> getMetaData()

Return any associated metadata with this AggregationBuilder.

subAggregation

public abstract AggregationBuilder subAggregation(AggregationBuilder aggregation)

Add a sub aggregation to this builder.

subAggregation

public abstract AggregationBuilder subAggregation(PipelineAggregationBuilder aggregation)

Add a sub aggregation to this builder.

getSubAggregations

public java.util.List<AggregationBuilder> getSubAggregations()

Return the configured set of subaggregations

getPipelineAggregations

public java.util.List<PipelineAggregationBuilder> getPipelineAggregations()

Return the configured set of pipeline aggregations

subAggregations

public abstract AggregationBuilder subAggregations(AggregatorFactories.Builder subFactories)

Internal: Registers sub-factories with this factory. The sub-factory will be responsible for the creation of sub-aggregators under the aggregator created by this factory. This is only for use by AggregatorFactories.parseAggregators(XContentParser).

Specified by:

subAggregations in interface BaseAggregationBuilder

Parameters:

subFactories - The sub-factories

Returns:

this factory (fluent interface)

shallowCopy

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

Create a shallow copy of this builder and replacing factoriesBuilder and metaData. Used by rewrite(QueryRewriteContext).

rewrite

public final AggregationBuilder rewrite(QueryRewriteContext context)
                                 throws java.io.IOException

Throws:

java.io.IOException

doRewrite

protected AggregationBuilder doRewrite(QueryRewriteContext queryShardContext)
                                throws java.io.IOException

Rewrites this aggregation builder into its primitive form. By default this method return the builder itself. If the builder did not change the identity reference must be returned otherwise the builder will be rewritten infinitely.

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
