  • Constructor Details

    • DateHistogramGroupConfig

      @Deprecated public DateHistogramGroupConfig​(java.lang.String field, interval)
      Create a new DateHistogramGroupConfig using the given field and interval parameters.
    • DateHistogramGroupConfig

      @Deprecated public DateHistogramGroupConfig​(java.lang.String field, interval, @Nullable delay, @Nullable java.lang.String timeZone)
      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.

      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.

    • validate

      public java.util.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
      An Optional ValidationException that contains a list of validation errors.
