Overview

Note:

When passing Transform as input to an Aws::Client method, you can use a vanilla Hash:

{
  expression: "Expression", # required
  variables: [ # required
    {
      name: "VariableName", # required
      value: { # required
        property_id: "Macro", # required
        hierarchy_id: "Macro",
      },
    },
  ],
}

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.
