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 .
Example
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
