Method Detail

parse

public static HistogramAggregationBuilder parse(java.lang.String aggregationName,
                                                XContentParser parser)

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)
                     throws java.io.IOException

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<ValuesSource.Numeric,HistogramAggregationBuilder>

Throws:

java.io.IOException

interval

public double interval()

Get the current interval that is set on this builder.
