#apply_cross_stack_reference_strength(strength) ⇒ void

This method returns an undefined value.

Override the cross-stack reference strength for this resource.

When set, any cross-stack reference to this resource will use the specified mechanism instead of the global default determined by the @aws-cdk/core:defaultCrossStackReferences context key. This is useful for selectively weakening specific references to avoid the "deadly embrace" problem without changing the app-wide default.

  jsii_call_method("applyCrossStackReferenceStrength", [strength])
end

#apply_removal_policy(policy) ⇒ void

This method returns an undefined value.

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:

#consider_warning_on_invoke_function_permissions(_scope, _action) ⇒ void

This method returns an undefined value.

A warning will be added to functions under the following conditions: - permissions that include lambda:InvokeFunction are added to the unqualified function.

  • function.currentVersion is invoked before or after the permission is created.

This applies only to permissions on Lambda functions, not versions or aliases. This function is overridden as a noOp for QualifiedFunctionBase.

Parameters:

  • _scope (Constructs::Construct)
  • _action (String)

  jsii_call_method("considerWarningOnInvokeFunctionPermissions", [_scope, _action])
end

#env ⇒ AWSCDK::Interfaces::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.

Returns:

end

#get_resource_arn_attribute(arn_attr, arn_components) ⇒ String

Returns an environment-sensitive token that should be used for the resource's "ARN" attribute (e.g. bucket.bucketArn).

Normally, this token will resolve to arn_attr, but if the resource is referenced across environments, arn_components will be used to synthesize a concrete ARN with the resource's physical name. Make sure to reference this.physicalName in arn_components.

Parameters:

  • arn_attr (String) —

    The CFN attribute which resolves to the ARN of the resource.

  • arn_components (AWSCDK::ARNComponents) —

    The format of the ARN of this resource.

Returns:

#get_resource_name_attribute(name_attr) ⇒ String

Returns an environment-sensitive token that should be used for the resource's "name" attribute (e.g. bucket.bucketName).

Normally, this token will resolve to name_attr, but if the resource is referenced across environments, it will be resolved to this.physicalName, which will be a concrete name.

Parameters:

  • name_attr (String) —

    The CFN attribute which resolves to the resource's name.
