// Get interpolated values for an asset property for a specified time interval,
// during a period of time. If your time series is missing data points during the
// specified time interval, you can use interpolation to estimate the missing data.
// 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. To identify
// an asset property, you must specify one of the following:
//   - The assetId and propertyId of an asset property.
//   - A propertyAlias , which is a data stream alias (for example,
//     /company/windfarm/3/turbine/7/temperature ). To define an asset property's
//     alias, see UpdateAssetProperty (https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_UpdateAssetProperty.html)

	// The interpolation type. Valid values: LINEAR_INTERPOLATION | LOCF_INTERPOLATION
	//   - LINEAR_INTERPOLATION – Estimates missing data using linear interpolation (https://en.wikipedia.org/wiki/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.

	// 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
