Language	Type name
.NET	Amazon.CDK.AWS.IoTSiteWise.CfnAssetModel.TransformProperty
Java	software.amazon.awscdk.services.iotsitewise.CfnAssetModel.TransformProperty
Python	aws_cdk.aws_iotsitewise.CfnAssetModel.TransformProperty
TypeScript	@aws-cdk/aws-iotsitewise » CfnAssetModel » TransformProperty

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. Transforms can only input properties that are INTEGER , DOUBLE , or BOOLEAN type. Booleans convert to 0 ( FALSE ) and 1 ( TRUE )..

For more information, see Defining data properties in the AWS IoT SiteWise User Guide .

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as iotsitewise from '@aws-cdk/aws-iotsitewise';
const transformProperty: iotsitewise.CfnAssetModel.TransformProperty = {
  expression: 'expression',
  variables: [{
    name: 'name',
    value: {
      propertyLogicalId: 'propertyLogicalId',

      // the properties below are optional
      hierarchyLogicalId: 'hierarchyLogicalId',
    },
  }],
};
