Constructor Details

DateHistogramAggregationBuilder

public DateHistogramAggregationBuilder(java.lang.String name)

Create a new builder with the given name.

DateHistogramAggregationBuilder

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

DateHistogramAggregationBuilder

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

Read from a stream, for internal use only.

Throws:

java.io.IOException

Method Details

registerAggregators

public static void registerAggregators(ValuesSourceRegistry.Builder builder)

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

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 java.io.IOException

Description copied from class: ValuesSourceAggregationBuilder

Write subclass's state to the stream.

Specified by:

innerWriteTo in class ValuesSourceAggregationBuilder<DateHistogramAggregationBuilder>

Throws:

java.io.IOException

interval

@Deprecated public long interval()

Deprecated.

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

Specified by:

interval in interface DateIntervalConsumer

interval

@Deprecated public DateHistogramAggregationBuilder interval(long interval)

Deprecated.

use fixedInterval(DateHistogramInterval) or calendarInterval(DateHistogramInterval) instead

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.

Specified by:

interval in interface DateIntervalConsumer

Since:

7.2.0

dateHistogramInterval

@Deprecated public DateHistogramInterval dateHistogramInterval()

Deprecated.

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

Specified by:

dateHistogramInterval in interface DateIntervalConsumer

dateHistogramInterval

@Deprecated public DateHistogramAggregationBuilder dateHistogramInterval(DateHistogramInterval interval)

Deprecated.

use fixedInterval(DateHistogramInterval) or calendarInterval(DateHistogramInterval) instead

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.

Specified by:

dateHistogramInterval in interface DateIntervalConsumer

Since:

7.2.0

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

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

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

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)

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.

parseStringOffset

public static long parseStringOffset(java.lang.String offset)

Parse the string specification of an offset.

extendedBounds

public LongBounds extendedBounds()

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

public DateHistogramAggregationBuilder extendedBounds(LongBounds extendedBounds)

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

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.

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()
