@Stability(value=Stable) @NotNull protected String allocateLogicalId(@NotNull CfnElement cfnElement)
By default, uses
the HashedAddressingScheme
but this method can be overridden to customize
this behavior.
In order to make sure logical IDs are unique and stable, we hash the resource construct tree path (i.e. toplevel/secondlevel/.../myresource) and add it as a suffix to the path components joined without a separator (CloudFormation IDs only allow alphanumeric characters).
The result will be:
<path.join('')><md5(path.join('/')> "human" "hash"
If the "human" part of the ID exceeds 240 characters, we simply trim it so the total ID doesn't exceed CloudFormation's 255 character limit.
We only take 8 characters from the md5 hash (0.000005 chance of collision).
Special cases:
L1/L2/Pipeline/Pipeline
), they will be de-duplicated to make the
resulting human portion of the ID more pleasing: L1L2Pipeline<HASH>
instead of L1L2PipelinePipeline<HASH>
cfnElement
- The element for which the logical ID is allocated. This parameter is required.@Stability(value=Stable) @NotNull public String exportValue(@NotNull Object exportedValue, @Nullable ExportValueOptions options)
Returns a string representing the corresponding Fn.importValue()
expression for this Export. You can control the name for the export by
passing the name
option.
If you don't supply a value for name
, the value you're exporting must be
a Resource attribute (for example: bucket.bucketName
) and it will be
given the same name as the automatic cross-stack reference that would be created
if you used the attribute in another Stack.
One of the uses for this method is to remove the relationship between two Stacks established by automatic cross-stack references. It will temporarily ensure that the CloudFormation Export still exists while you remove the reference from the consuming stack. After that, you can remove the resource and the manual export.
Here is how the process works. Let's say there are two stacks,
producerStack
and consumerStack
, and producerStack
has a bucket
called bucket
, which is referenced by consumerStack
(perhaps because
an AWS Lambda Function writes into it, or something like that).
It is not safe to remove producerStack.bucket
because as the bucket is being
deleted, consumerStack
might still be using it.
Instead, the process takes two deployments:
consumerStack
no longer references bucket.bucketName
(maybe the consumer
stack now uses its own bucket, or it writes to an AWS DynamoDB table, or maybe you just
remove the Lambda Function altogether).ProducerStack
class, call this.exportValue(this.bucket.bucketName)
. This
will make sure the CloudFormation Export continues to exist while the relationship
between the two stacks is being broken.consumerStack

- This parameter is required.@Stability(value=Stable) @NotNull public String formatArn(@NotNull ArnComponents components)
If partition
, region
or account
are not specified, the stack's
partition, region and account will be used.
If any component is the empty string, an empty string will be inserted into the generated ARN at the location that component corresponds to.
The ARN will be formatted as follows:
arn:{partition}:{service}:{region}:{account}:{resource}{sep}}{resource-name}
The required ARN pieces that are omitted will be taken from the stack that the 'scope' is attached to. If all ARN pieces are supplied, the supplied scope can be 'undefined'.
components
- This parameter is required.@Stability(value=Stable) @NotNull public String getLogicalId(@NotNull CfnElement element)
This method is called when a CfnElement
is created and used to render the
initial logical identity of resources. Logical ID renames are applied at
this stage.
This method uses the protected method allocateLogicalId
to render the
logical ID for an element. To modify the naming scheme, extend the Stack
class and override this method.
element
- The CloudFormation element for which a logical identity is needed. This parameter is required.@Stability(value=Deprecated) @Deprecated @NotNull public ArnComponents parseArn(@NotNull String arn, @Nullable String sepIfToken, @Nullable Boolean hasName)

...it will be parsed and validated. The separator (sep
) will be set to '/'
if the 6th component includes a '/', in which case, resource
will be set
to the value before the '/' and resourceName
will be the rest. In case

will be set to the 6th components and
resourceName
will be set to the rest of the string.
IF THE ARN IS A TOKEN...
...it cannot be validated, since we don't have the actual value yet at the
time of this function call. You will have to supply sepIfToken
and
whether or not ARNs of the expected format usually have resource names
in order to parse it properly. The resulting ArnComponents
object will
contain tokens for the subexpressions of the ARN, not string literals.
If the resource name could possibly contain the separator char, the actual
resource name cannot be properly parsed. This only occurs if the separator
char is '/', and happens for example for S3 object ARNs, IAM Role ARNs,
IAM OIDC Provider ARNs, etc. To properly extract the resource name from a
Tokenized ARN, you must know the resource type and call
Arn.extractResourceName

@Stability(value=Stable) @NotNull public String regionalFact(@NotNull String factName, @Nullable String defaultValue)
Will return a definite value only if the region of the current stack is resolved. If not, a lookup map will be added to the stack and the lookup will be done at CDK deployment time.
What regions will be included in the lookup map is controlled by the
@aws-cdk/core:target-partitions
context value: it must be set to a list
of partitions, and only regions from the given partitions will be included.
If no such context key is set, all regions will be included.
This function is intended to be used by construct library authors. Application builders can rely on the abstractions offered by construct libraries and do not have to worry about regional facts.
If defaultValue
is not given, it is an error if the fact is unknown for
the given region.

This value is resolved according to the following rules:
env.account
when the stack is defined. This can
either be a concerete account (e.g. 585695031111
) or the
Aws.accountId
token.Aws.accountId
, which represents the CloudFormation intrinsic reference
{ "Ref": "AWS::AccountId" }
encoded as a string token.
Preferably, you should use the return value as an opaque string and not
attempt to parse it to implement your logic. If you do, you must first
check that it is a concerete value an not an unresolved token. If this
value is an unresolved token (Token.isUnresolved(stack.account)
returns
true
), this implies that the user wishes that this stack will synthesize
into a account-agnostic template. In this case, your code should either
fail (throw an error, emit a synth error using Annotations.of(construct).addError()
) or
implement some other region-agnostic behavior.
@Stability(value=Stable) @NotNull public String getArtifactId()
@Stability(value=Stable) @NotNull public List<String> getAvailabilityZones()
If the stack is environment-agnostic (either account and/or region are
tokens), this property will return an array with 2 tokens that will resolve
at deploy-time to the first two availability zones returned from CloudFormation's
Fn::GetAZs
intrinsic function.
If they are not available in the context, returns a set of dummy values and
reports them as missing, and let the CLI resolve them by calling EC2
DescribeAvailabilityZones
on the target environment.
To specify a different strategy for selecting availability zones override this method.
@Stability(value=Stable) @NotNull public List<Stack> getDependencies()
@Stability(value=Stable) @NotNull public String getEnvironment()
In the form
aws://account/region
. Use stack.account
and stack.region
to obtain
the specific values, no need to parse.
You can use this value to determine if two stacks are targeting the same environment.
If either stack.account
or stack.region
are not concrete values (e.g.
Aws.account
or Aws.region
) the special strings unknown-account
and/or
unknown-region
will be used respectively to indicate this stack is
region/account-agnostic.

This value is resolved according to the following rules:

when the stack is defined. This can
either be a concerete region (e.g. us-west-2
) or the Aws.region
token.Aws.region
, which is represents the CloudFormation intrinsic reference

encoded as a string token.
Preferably, you should use the return value as an opaque string and not

@Stability(value=Stable) @NotNull public String getStackName()
This is either the name defined explicitly in the stackName

are directly defined under the app use their construct id
as their stack

scheme based on the construct path to ensure uniqueness.

you can use Aws.stackName
directly.
