Input

class aws_cdk.aws_iotevents_alpha.Input(scope, id, *, attribute_json_paths, input_name=None)

Bases: Resource

(experimental) Defines an AWS IoT Events input in this stack.

Stability:: experimental
ExampleMetadata:: infused

Example:

import aws_cdk.aws_iotevents_alpha as iotevents
import aws_cdk.aws_iam as iam

# role: iam.IRole


input = iotevents.Input(self, "MyInput",
    attribute_json_paths=["payload.temperature", "payload.transactionId"]
)
topic_rule = iot.TopicRule(self, "TopicRule",
    sql=iot.IotSql.from_string_as_ver20160323("SELECT * FROM 'device/+/data'"),
    actions=[
        actions.IotEventsPutMessageAction(input,
            batch_mode=True,  # optional property, default is 'false'
            message_id="${payload.transactionId}",  # optional property, default is a new UUID
            role=role
        )
    ]
)

Parameters:

scope (Construct) –
id (str) –
attribute_json_paths (Sequence[str]) – (experimental) An expression that specifies an attribute-value pair in a JSON structure. Use this to specify an attribute from the JSON payload that is made available by the input. Inputs are derived from messages sent to AWS IoT Events (BatchPutMessage). Each such message contains a JSON payload. The attribute (and its paired value) specified here are available for use in the condition expressions used by detectors.
input_name (Optional[str]) – (experimental) The name of the input. Default: - CloudFormation will generate a unique name of the input

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (RemovalPolicy) –

Return type:

None

grant(grantee, *actions)

(experimental) Grant the indicated permissions on this input to the given IAM principal (Role/Group/User).

Parameters:

grantee (IGrantable) –
actions (str) –

Stability:

experimental

Return type:

Grant

grant_write(grantee)

(experimental) Grant write permissions on this input and its contents to an IAM principal (Role/Group/User).

Parameters:

grantee (IGrantable) –

Stability:

experimental

Return type:

Grant

to_string()

Returns a string representation of this construct.

Return type:: str

Attributes

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

input_arn

(experimental) The ARN of the input.

Stability:: experimental

input_name

(experimental) The name of the input.

Stability:: experimental

node: The tree node.

stack: The stack in which this resource is defined.

Static Methods

classmethod from_input_name(scope, id, input_name)

(experimental) Import an existing input.

Parameters:

scope (Construct) –
id (str) –
input_name (str) –

Stability:

experimental

Return type:

IInput

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:

construct (IConstruct) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
