        Returns:
        The maximum number of results to return for each paginated request. If not specified, the default value is 10.

      • type

        public final String type()

        The interpolation type.

        Valid values: LINEAR_INTERPOLATION | LOCF_INTERPOLATION

        • LINEAR_INTERPOLATION – Estimates missing data using linear interpolation.

          For example, you can use this operation to return the interpolated temperature values for a wind turbine every 24 hours over a duration of 7 days. If the interpolation starts July 1, 2021, at 9 AM, IoT SiteWise returns the first interpolated value on July 2, 2021, at 9 AM, the second interpolated value on July 3, 2021, at 9 AM, and so on.

        • LOCF_INTERPOLATION – Estimates missing data using last observation carried forward interpolation

          If no data point is found for an interval, IoT SiteWise returns the last observed data point for the previous interval and carries forward this interpolated value until a new data point is found.

          For example, you can get the state of an on-off valve every 24 hours over a duration of 7 days. If the interpolation starts July 1, 2021, at 9 AM, IoT SiteWise returns the last observed data point between July 1, 2021, at 9 AM and July 2, 2021, at 9 AM as the first interpolated value. If a data point isn't found after 9 AM on July 2, 2021, IoT SiteWise uses the same interpolated value for the rest of the days.

        Returns:
        The interpolation type.

        Valid values: LINEAR_INTERPOLATION | LOCF_INTERPOLATION

        • LINEAR_INTERPOLATION – Estimates missing data using linear interpolation.

          For example, you can use this operation to return the interpolated temperature values for a wind turbine every 24 hours over a duration of 7 days. If the interpolation starts July 1, 2021, at 9 AM, IoT SiteWise returns the first interpolated value on July 2, 2021, at 9 AM, the second interpolated value on July 3, 2021, at 9 AM, and so on.

        • LOCF_INTERPOLATION – Estimates missing data using last observation carried forward interpolation

          If no data point is found for an interval, IoT SiteWise returns the last observed data point for the previous interval and carries forward this interpolated value until a new data point is found.

          For example, you can get the state of an on-off valve every 24 hours over a duration of 7 days. If the interpolation starts July 1, 2021, at 9 AM, IoT SiteWise returns the last observed data point between July 1, 2021, at 9 AM and July 2, 2021, at 9 AM as the first interpolated value. If a data point isn't found after 9 AM on July 2, 2021, IoT SiteWise uses the same interpolated value for the rest of the days.

      • intervalWindowInSeconds

        public final Long intervalWindowInSeconds()

        The query interval for the window, in seconds. IoT SiteWise computes each interpolated value by using data points from the timestamp of each interval, minus the window to the timestamp of each interval plus the window. If not specified, the window ranges between the start time minus the interval and the end time plus the interval.

        • If you specify a value for the intervalWindowInSeconds parameter, the value for the type parameter must be LINEAR_INTERPOLATION.

        • If a data point isn't found during the specified query window, IoT SiteWise won't return an interpolated value for the interval. This indicates that there's a gap in the ingested data points.

        For example, you can get the interpolated temperature values for a wind turbine every 24 hours over a duration of 7 days. If the interpolation starts on July 1, 2021, at 9 AM with a window of 2 hours, IoT SiteWise uses the data points from 7 AM (9 AM minus 2 hours) to 11 AM (9 AM plus 2 hours) on July 2, 2021 to compute the first interpolated value. Next, IoT SiteWise uses the data points from 7 AM (9 AM minus 2 hours) to 11 AM (9 AM plus 2 hours) on July 3, 2021 to compute the second interpolated value, and so on.

        Returns:
        The query interval for the window, in seconds. IoT SiteWise computes each interpolated value by using data points from the timestamp of each interval, minus the window to the timestamp of each interval plus the window. If not specified, the window ranges between the start time minus the interval and the end time plus the interval.

        • If you specify a value for the intervalWindowInSeconds parameter, the value for the type parameter must be LINEAR_INTERPOLATION.

        • If a data point isn't found during the specified query window, IoT SiteWise won't return an interpolated value for the interval. This indicates that there's a gap in the ingested data points.

        For example, you can get the interpolated temperature values for a wind turbine every 24 hours over a duration of 7 days. If the interpolation starts on July 1, 2021, at 9 AM with a window of 2 hours, IoT SiteWise uses the data points from 7 AM (9 AM minus 2 hours) to 11 AM (9 AM plus 2 hours) on July 2, 2021 to compute the first interpolated value. Next, IoT SiteWise uses the data points from 7 AM (9 AM minus 2 hours) to 11 AM (9 AM plus 2 hours) on July 3, 2021 to compute the second interpolated value, and so on.
