env

Type: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed in a Stack (those created by creating new class instances like new Role(), new Bucket(), etc.), this is always the same as the environment of the stack they belong to.

For referenced resources (those obtained from referencing methods like Role.fromRoleArn(), Bucket.fromBucketName(), etc.), they might be different than the stack they were imported into.

---

isApplicationListener

Type: boolean

Indicates that this is an ALB listener.

Will always return true, but is necessary to prevent accidental structural equality in TypeScript.

---

listenerArn

Type: string

ARN of the listener.

---

listenerRef🔹

Type: ListenerReference

A reference to a Listener resource.

---

node

Type: Node

The tree node.

---

stack

Type: Stack

The stack in which this resource is defined.

Methods

Name	Description
applyRemovalPolicy(policy)	Apply the given removal policy to this resource.

---

applyRemovalPolicy(policy)

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

• policy RemovalPolicy

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).
