class Aws::IoTSiteWise::Types::Transform

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`.

@note When making an API call, you may pass Transform

data as a hash:

    {
      expression: "Expression", # required
      variables: [ # required
        {
          name: "VariableName", # required
          value: { # required
            property_id: "Macro", # required
            hierarchy_id: "Macro",
          },
        },
      ],
      processing_config: {
        compute_location: "EDGE", # required, accepts EDGE, CLOUD
        forwarding_config: {
          state: "DISABLED", # required, accepts DISABLED, ENABLED
        },
      },
    }

@!attribute [rw] expression

The mathematical expression that defines the transformation
function. You can specify up to 10 variables per expression. You can
specify up to 10 functions per expression.

@return [String]

@!attribute [rw] variables

The list of variables used in the expression.
@return [Array<Types::ExpressionVariable>]

@!attribute [rw] processing_config

The processing configuration for the given transform property. You
can configure transforms to be kept at the edge or forwarded to the
Amazon Web Services Cloud. You can also configure transforms to be
computed at the edge or in the cloud.
@return [Types::TransformProcessingConfig]
