Constructor Details

ValuesSourceAggregationBuilder

protected ValuesSourceAggregationBuilder(String name)

ValuesSourceAggregationBuilder

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

ValuesSourceAggregationBuilder

protected ValuesSourceAggregationBuilder(StreamInput in)
                                  throws IOException

Read from a stream.

Throws:

IOException

public static <T> void declareFields(AbstractObjectParser<? extends ValuesSourceAggregationBuilder<?>,T> objectParser,
 boolean scriptable,
 boolean formattable,
 boolean timezoneAware)

declareFields

doWriteTo

protected final void doWriteTo(StreamOutput out)
                        throws IOException

Specified by:

doWriteTo in class AbstractAggregationBuilder<AB extends ValuesSourceAggregationBuilder<AB>>

Throws:

IOException

innerWriteTo

protected abstract void innerWriteTo(StreamOutput out)
                              throws IOException

Write subclass's state to the stream.

Throws:

IOException

serializeTargetValueType

protected boolean serializeTargetValueType(TransportVersion version)

DO NOT OVERRIDE THIS!

This method only exists for legacy support. No new aggregations need this, nor should they override it.

Parameters:

version - For backwards compatibility, subclasses can change behavior based on the version

field

public AB field(String field)

Sets the field to use for this aggregation.

field

public String field()

Gets the field to use for this aggregation.

script

public AB script(Script script)

Sets the script to use for this aggregation.

script

public Script script()

Gets the script to use for this aggregation.

userValueTypeHint

public AB userValueTypeHint(ValueType valueType)

This setter should only be used during parsing, to set the userValueTypeHint. This is information the user provides in the json query to indicate the output type of a script or the type of the 'missing' replacement value.

Parameters:

valueType - - The parsed ValueType based on the string the user specified

Returns:

- The modified builder instance, for chaining.

userValueTypeHint

public ValueType userValueTypeHint()

format

public AB format(String format)

Sets the format to use for the output of the aggregation.

format

public String format()

Gets the format to use for the output of the aggregation.

missing

public AB missing(Object missing)

Sets the value to use when the aggregation finds a missing value in a document

timeZone

public AB timeZone(ZoneId timeZone)

Sets the time zone to use for this aggregation

timeZone

public ZoneId timeZone()

Gets the time zone to use for this aggregation

doBuild

protected final ValuesSourceAggregatorFactory doBuild(AggregationContext context,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                               throws IOException

Specified by:

doBuild in class AbstractAggregationBuilder<AB extends ValuesSourceAggregationBuilder<AB>>

Throws:

IOException

defaultValueSourceType

protected abstract ValuesSourceType defaultValueSourceType()

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.

Returns:

The CoreValuesSourceType we expect this script to yield.

resolveConfig

protected ValuesSourceConfig resolveConfig(AggregationContext context)

Aggregations should override this if they need non-standard logic for resolving where to get values from. For example, join aggregations (like Parent and Child) ask the user to specify one side of the join and then look up the other field to read values from.

The default implementation just uses the field and/or script the user provided.

Returns:

A ValuesSourceConfig configured based on the parsed field and/or script.

innerBuild

protected abstract ValuesSourceAggregatorFactory innerBuild(AggregationContext context,
 ValuesSourceConfig config,
 AggregatorFactory parent,
 AggregatorFactories.Builder subFactoriesBuilder)
                                                     throws IOException

Throws:

IOException

internalXContent

public final XContentBuilder internalXContent(XContentBuilder builder,
 ToXContent.Params params)
                                       throws IOException

Specified by:

internalXContent in class AbstractAggregationBuilder<AB extends ValuesSourceAggregationBuilder<AB>>

Throws:

IOException

doXContentBody

protected abstract XContentBuilder doXContentBody(XContentBuilder builder,
 ToXContent.Params params)
                                           throws IOException

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractAggregationBuilder<AB extends ValuesSourceAggregationBuilder<AB>>

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractAggregationBuilder<AB extends ValuesSourceAggregationBuilder<AB>>
