Jezza updated WICKET-6550:
--------------------------
Attachment: Test.java
> Unify all metadata capable objects.
> -----------------------------------
>
> Key: WICKET-6550
> URL: https://issues.apache.org/jira/browse/WICKET-6550
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Reporter: Jezza
> Priority: Minor
> Attachments: Test.java, mock.txt
>
>
> Application, Session, RequestCycle, and Component all have #setMetadata and
> #getMetadata methods, but lack some super object to unify them all.
> These leads to annoying complex code if you wish to implement some basic
> functionality.
> Such as a computeIfAbsent, which needs to be implemented 4 times.
> I propose that we unify them all with one interface.
> I've attached a mock idea that would solve it, and I'll work on a prototype
> and submit a PR so anyone can take a look.
> I'll add a comment here with the PR number.
