Class: AWSCDK::IoTSiteWise::CfnAssetModel::TransformProperty

Inherits:

Jsii::Struct

• Object
• Jsii::Struct
• AWSCDK::IoTSiteWise::CfnAssetModel::TransformProperty

Defined in:

io_t_site_wise/cfn_asset_model.rb

Overview

Contains an asset transform property.

A transform is a one-to-one mapping of a property's data points from one form to another. For example, you can use a transform to convert a Celsius data stream to Fahrenheit by applying the transformation expression to each data point of the Celsius stream. A transform can only have a data type of DOUBLE and consume properties with data types of INTEGER or DOUBLE .

For more information, see Transforms in the AWS IoT SiteWise User Guide .
