Sven Meier updated WICKET-5350:
-------------------------------
Assignee: Sven Meier
Summary: Enhancement for AbstractChoice and WildcardListModel API (was: Enahancement for AbstractChoice and WildcardListModel API)
> Enhancement for AbstractChoice and WildcardListModel API
> --------------------------------------------------------
>
> Key: WICKET-5350
> URL: https://issues.apache.org/jira/browse/WICKET-5350
> Project: Wicket
> Issue Type: Improvement
> Affects Versions: 6.10.0, 7.0.0-M1
> Reporter: Betlista
> Assignee: Sven Meier
> Priority: Minor
> Labels: generics
>
> According to Efective Java book (http://devender.files.wordpress.com/2008/05/effectivejava.pdf), item 28:
> "No wildcard type for return value"
> Especially "User should not have to think about wildcards to use your API".
> so
> public List<? extends E> getChoices()
> should be changed to
> public List<E> getChoices()
> and for WildcardListModel
> protected List<? extends T> createSerializableVersionOf(List<? extends T> object)
> should be changed to
> protected List<T> createSerializableVersionOf(List<? extends T> object)
> Probably there is a lot of such things in framework.
