[cdi-dev] [JBoss JIRA] (CDI-686) Could InterceptionFactory accept an interface as type parameter

[Thomas Andraschko (JIRA)]

    [ https://issues.jboss.org/browse/CDI-686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13367953#comment-13367953 ] 

Thomas Andraschko commented on CDI-686:
---------------------------------------

+1 romain. Same for abstract classes.
Mabye it would be great if the CDI API would allow the same features as the DS PartialBean module. Shoudln't be that hard. AFAIR the code is almost already availble in OWB, we would just need a nice API (like introducing a @PartialBeanBinding).

> If you take this code:

>     @Produces
>     public List<Object> produceList(InterceptionFactory<List<Object>> interceptionFactory) {
>         interceptionFactory.ignoreFinalMethods().configure().filterMethods((m) -> {
>             if (m.getJavaMember().getName().equals("add")
>                     && m.getJavaMember().getParameterCount() == 1) {
>                 return true;
>             }
>             return false;
>         }).findFirst().get().add(Monitor.Literal.INSTANCE);
>         return interceptionFactory.createInterceptedInstance(new ArrayList<>());
>     }
> {code}
> Parameterized type for injected {{InterceptionFactory}} is an interface {{List<Object>}}, so when calling {{configure()}}, user will work with an {{AnnotatedTypeConfigurator<List<Object>>}} to apply interceptor binding.
> In a standard interceptor usage, interceptor binding on interface are ignored (even if they have {{@Inherited}} annotation), so doing it with {{InterceptionFactory}} could be confusing for some user.
