Defined in:

Overview

A structure that contains an asset property value.

For more information, see Variant in the AWS IoT SiteWise API Reference .

You must use expressions for all parameters in AssetPropertyVariant . The expressions accept literals, operators, functions, references, and substitution templates.

Examples - For literal values, the expressions must contain single quotes. For example, the value for the integer_value parameter can be '100' .

  • For references, you must specify either variables or parameters. For example, the value for the boolean_value parameter can be $variable.offline .
  • For a substitution template, you must use ${} , and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.

In the following example, the value for the double_value parameter uses a substitution template.

'${$input.TemperatureInput.sensorData.temperature * 6 / 5 + 32}'

For more information, see Expressions in the AWS IoT Events Developer Guide .

You must specify one of the following value types, depending on the data_type of the specified asset property. For more information, see AssetProperty in the AWS IoT SiteWise API Reference .
