Receipt Detector Model actions for AWS IoT Events

Actions for AWS::IoTEvents Detector Model

---

The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.

---

This library contains integration classes to specify actions of state events of Detector Model in @aws-cdk/aws-iotevents. Instances of these classes should be passed to State defined in @aws-cdk/aws-iotevents You can define built-in actions to use a timer or set a variable, or send data to other AWS resources.

This library contains integration classes to use a timer or set a variable, or send data to other AWS resources. AWS IoT Events can trigger actions when it detects a specified event or transition event.

Currently supported are:

• Set variable to detector instanse
• Invoke a Lambda function

Set variable to detector instanse

The code snippet below creates an Action that set variable to detector instanse when it is triggered.

# Example automatically generated from non-compiling source. May contain errors.
import aws_cdk.aws_iotevents as iotevents
import aws_cdk.aws_iotevents_actions as actions

# input: iotevents.IInput

state = iotevents.State(
    state_name="MyState",
    on_enter=[iotevents.Event(
        event_name="test-event",
        condition=iotevents.Expression.current_input(input),
        actions=[actions, [
            actions.SetVariableAction("MyVariable",
                iotevents.Expression.input_attribute(input, "payload.temperature"))
        ]
        ]
    )]
)

Invoke a Lambda function

The code snippet below creates an Action that invoke a Lambda function when it is triggered.

import aws_cdk.aws_iotevents as iotevents
import aws_cdk.aws_iotevents_actions as actions
import aws_cdk.aws_lambda as lambda_

# input: iotevents.IInput
# func: lambda.IFunction

state = iotevents.State(
    state_name="MyState",
    on_enter=[iotevents.Event(
        event_name="test-event",
        condition=iotevents.Expression.current_input(input),
        actions=[actions.LambdaInvokeAction(func)]
    )]
)
