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 ‘integerValue` parameter can be `’100’‘.

  • For references, you must specify either variables or parameters. For example, the value for the ‘booleanValue` 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 ‘doubleValue` parameter uses a substitution template.

    ‘’$* 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 ‘dataType` of the specified asset property. For more information, see
