Jezza created WICKET-6550:
-----------------------------
Summary: 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
Attachments: 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.
