AWS::IoTEvents::DetectorModel AssetPropertyVariant
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.
