DateHistogramGroupConfig

@Deprecated
public DateHistogramGroupConfig(String field,
                                DateHistogramInterval interval,
                                @Nullable
                                DateHistogramInterval delay,

Deprecated.

Build a DateHistoConfig using DateHistogramGroupConfig.CalendarInterval or DateHistogramGroupConfig.FixedInterval instead

Create a new DateHistogramGroupConfig using the given configuration parameters.

The field and interval are required to compute the date histogram for the rolled up documents. The delay is optional and can be set to null. It defines how long to wait before rolling up new documents. The timeZone is optional and can be set to null. When configured, the time zone value is resolved using (DateTimeZone.forID(String) and must match a time zone identifier provided by the Joda Time library.

Parameters:

field - the name of the date field to use for the date histogram (required)

interval - the interval to use for the date histogram (required)

delay - the time delay (optional)

timeZone - the id of time zone to use to calculate the date histogram (optional). When null, the UTC timezone is used.

Since:

7.2.0

Method Detail

validate

public Optional<ValidationException> validate()

Description copied from interface: Validatable

Perform validation. This method does not have to be overridden in the event that no validation needs to be done, or the validation was done during object construction time. A ValidationException that is not null is assumed to contain validation errors and will be thrown.

Specified by:

validate in interface Validatable

Returns:

An Optional ValidationException that contains a list of validation errors.

getField

public String getField()

Get the date field

getInterval

public DateHistogramInterval getInterval()

Get the date interval

getDelay

public DateHistogramInterval getDelay()

Get the time delay for this histogram

getTimeZone

public String getTimeZone()

Get the timezone to apply

toXContent

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

Specified by:

toXContent in interface ToXContent

Throws:

IOException

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

fromXContent

public static DateHistogramGroupConfig fromXContent(XContentParser parser)
                                             throws IOException
