Constructor Details

VariableWidthHistogramAggregationBuilder

public VariableWidthHistogramAggregationBuilder(String name)

Create a new builder with the given name.

VariableWidthHistogramAggregationBuilder

public VariableWidthHistogramAggregationBuilder(StreamInput in)
                                         throws IOException

Read in object data from a stream, for internal use only.

Throws:

IOException

VariableWidthHistogramAggregationBuilder

 Map<String,Object> metaData)

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<VariableWidthHistogramAggregationBuilder>

Returns:

The CoreValuesSourceType we expect this script to yield.

setNumBuckets

public VariableWidthHistogramAggregationBuilder setNumBuckets(int numBuckets)

setShardSize

public VariableWidthHistogramAggregationBuilder setShardSize(int shardSize)

setInitialBuffer

public VariableWidthHistogramAggregationBuilder setInitialBuffer(int initialBuffer)

getShardSize

public int getShardSize()

getInitialBuffer

public int getInitialBuffer()

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

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

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<VariableWidthHistogramAggregationBuilder>

Throws:

IOException
