public abstract class CfnRefElement
extends CfnElement

Base class for referenceable CloudFormation constructs which are not Resources.

These constructs are things like Conditions and Parameters, can be referenced by taking the .ref attribute.

Resource constructs do not inherit from CfnRefElement because they have their own, more specific types returned from the .ref attribute. Also, some resources aren't referenceable at all (such as BucketPolicies or GatewayAttachments).

CfnRefElement

protected CfnRefElement(software.constructs.Construct scope,
                        java.lang.String id)

Creates an entity and binds it to a tree.

Note that the root of the tree must be a Stack object (not just any Root).

Parameters:

scope - The parent construct. This parameter is required.

id - This parameter is required.

Method Detail

getRef

public java.lang.String getRef()

Return a string that will be resolved to a CloudFormation `{ Ref }` for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).
