Constructor Details

DateHistogramAggregationBuilder

public DateHistogramAggregationBuilder(String name)

Create a new builder with the given name.

DateHistogramAggregationBuilder

protected DateHistogramAggregationBuilder(DateHistogramAggregationBuilder clone,
 AggregatorFactories.Builder factoriesBuilder,
 Map<String,Object> metadata)

DateHistogramAggregationBuilder

public DateHistogramAggregationBuilder(StreamInput in)
                                throws IOException

Read from a stream, for internal use only.

Throws:

IOException

Method Details

registerAggregators

public static void registerAggregators(ValuesSourceRegistry.Builder builder)

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. Used by AggregationBuilder.rewrite(QueryRewriteContext).

Specified by:

shallowCopy in class AggregationBuilder

supportsSampling

public boolean supportsSampling()

Description copied from class: AggregationBuilder

Does this aggregation support running with in a sampling context. By default, it's false for all aggregations. If the sub-classed builder supports sampling, be sure of the following that the resulting internal aggregation objects override the InternalAggregation.finalizeSampling(SamplingContext) and scales any values that require scaling.

Overrides:

supportsSampling in class AggregationBuilder

Returns:

does this aggregation builder support sampling

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<DateHistogramAggregationBuilder>

Returns:

The CoreValuesSourceType we expect this script to yield.

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<DateHistogramAggregationBuilder>

Throws:

IOException

calendarInterval

public DateHistogramAggregationBuilder calendarInterval(DateHistogramInterval interval)

Sets the interval of the DateHistogram using calendar units (`1d`, `1w`, `1M`, etc). These units are calendar-aware, meaning they respect leap additions, variable days per month, etc. This is mutually exclusive with fixedInterval(DateHistogramInterval)

Specified by:

calendarInterval in interface DateIntervalConsumer<DateHistogramAggregationBuilder>

Parameters:

interval - The calendar interval to use with the aggregation

fixedInterval

public DateHistogramAggregationBuilder fixedInterval(DateHistogramInterval interval)

Sets the interval of the DateHistogram using fixed units (`1ms`, `1s`, `10m`, `4h`, etc). These are not calendar aware and are simply multiples of fixed, SI units. This is mutually exclusive with calendarInterval(DateHistogramInterval)

Specified by:

fixedInterval in interface DateIntervalConsumer<DateHistogramAggregationBuilder>

Parameters:

interval - The fixed interval to use with the aggregation

getCalendarInterval

public DateHistogramInterval getCalendarInterval()

Returns the interval as a date time unit if and only if it was configured as a calendar interval originally. Returns null otherwise.

getFixedInterval

public DateHistogramInterval getFixedInterval()

Returns the interval as a fixed time unit if and only if it was configured as a fixed interval originally. Returns null otherwise.

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(String offset)

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

parseStringOffset

public static long parseStringOffset(String offset)

extendedBounds

public LongBounds extendedBounds()

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

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

hardBounds

public DateHistogramAggregationBuilder hardBounds(LongBounds hardBounds)

Set hard bounds on this histogram, specifying boundaries outside which buckets cannot be created.

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(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.
