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
${}
, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.
In the following example, the value for the doubleValue
parameter uses a substitution template.
'${$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 dataType
of the specified asset property. For more information, see AssetProperty in the AWS IoT SiteWise API Reference .
