public HistogramAggregationBuilder(java.lang.String name)

Create a new builder with the given name.

HistogramAggregationBuilder

public HistogramAggregationBuilder(StreamInput in)
                            throws java.io.IOException

Read from a stream, for internal use only.

Throws:

java.io.IOException

Method Detail

parse

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

Throws:

java.io.IOException

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.

interval

public HistogramAggregationBuilder interval(double interval)

Set the interval on this builder, and return the builder so that calls can be chained.

offset

public double offset()

Get the current offset that is set on this builder.

offset

public HistogramAggregationBuilder offset(double offset)

Set the offset on this builder, and return the builder so that calls can be chained.

minBound

public double minBound()

Get the current minimum bound that is set on this builder.

maxBound

public double maxBound()

Get the current maximum bound that is set on this builder.

extendedBounds
