-- | A structure that contains an asset property value. For more information,
-- see
-- <https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_Variant.html 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
-- <https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-expressions.html 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
-- <https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_AssetProperty.html AssetProperty>
-- in the /AWS IoT SiteWise API Reference/.
