CfnParameter is not inheriting CfnRefElement Java

[fima-taf]

The Question

The documentation of the java class software.amazon.awscdk.core.CfnRefElement saying that '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.'
But CfnParameter (core) class is not inheriting CfnRefElement it inherits CfnElement class which doesn't have the .ref attribute and cannot be referenced to other classes. (unlike CfnResource, CfnMapping and others).

Is it a bug? Or is there a way to get the ref attribute from Cloudformation's Parameters attribute?

Environment

• CDK CLI Version: 1.12.0.DEVPREVIEW
• OS: Windows 10
• Language: Java

Hey @vBandiTv,

The CfnParameter construct is a generalization of Cloudformation Parameters in general, and is not itself a specific parameter. It is an element of a cfn construct, therefore inherits CfnElement.
The CfnRefElement class exists to allow for the creation of non-resource, referenceable, individual Cloudformation constructs. It is less specific than the CfnResource and extends CfnElement, just as CfnParameter does.
CfnParameter does not contain a .ref element because it is a lower-level generalization then would require one.

Please let me know if that helped answer your question!
