Constructor Detail

DateHistogramAggregationBuilder

public DateHistogramAggregationBuilder(java.lang.String name)

Create a new builder with the given name.

DateHistogramAggregationBuilder

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

Read from a stream, for internal use only.

Throws:

java.io.IOException

Method Detail

parse

public static DateHistogramAggregationBuilder 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,DateHistogramAggregationBuilder>

Throws:

java.io.IOException

interval

public long interval()

Get the current interval in milliseconds that is set on this builder.

interval

public DateHistogramAggregationBuilder interval(long interval)

Set the interval on this builder, and return the builder so that calls can be chained. If both interval() and dateHistogramInterval() are set, then the dateHistogramInterval() wins.

dateHistogramInterval

public DateHistogramInterval dateHistogramInterval()

Get the current date interval that is set on this builder.

dateHistogramInterval

public DateHistogramAggregationBuilder dateHistogramInterval(DateHistogramInterval dateHistogramInterval)

Set the interval on this builder, and return the builder so that calls can be chained. If both interval() and dateHistogramInterval() are set, then the dateHistogramInterval() wins.

offset

public long offset()

Get the offset to use when rounding, which is a number of milliseconds.

offset

public DateHistogramAggregationBuilder offset(long offset)

Set the offset on this builder, which is a number of milliseconds, and return the builder so that calls can be chained.

offset

public DateHistogramAggregationBuilder offset(java.lang.String offset)

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

extendedBounds

public ExtendedBounds extendedBounds()

Return extended bounds for this histogram, or null if none are set.

extendedBounds

public DateHistogramAggregationBuilder extendedBounds(ExtendedBounds extendedBounds)

Set extended bounds on this histogram, so that buckets would also be generated on intervals that did not match any documents.

order

public BucketOrder order()

Return the order to use to sort buckets of this histogram.

order

public DateHistogramAggregationBuilder order(BucketOrder order)

Set a new order on this builder and return the builder so that calls can be chained. A tie-breaker may be added to avoid non-deterministic ordering.

order

public DateHistogramAggregationBuilder order(java.util.List<BucketOrder> orders)

Sets the order in which the buckets will be returned. A tie-breaker may be added to avoid non-deterministic ordering.

keyed

public boolean keyed()

Return whether buckets should be returned as a hash. In case keyed is false, buckets will be returned as an array.
