[cdi-dev] [JBoss JIRA] (CDI-43) Allow Extensions to specify the annotations that they are interested in

[Jozef Hartinger (JIRA)]

     [ https://issues.jboss.org/browse/CDI-43?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jozef Hartinger reopened CDI-43:
--------------------------------



The body of the @WithAnnotations annotation should be

{code:JAVA}
Class<? extends Annotation>[] value();
{code}
instead of
{code:JAVA}
Class<?>[] value();
{code}

so that if a class that is not an annotation type is used, this error is caught at the compile time

> Currently portable extensions that wish to look for a specific annotation have to look through all availible classes in the ProcessAnnotatatedType event, which is quite inefficient. It would be good if extensions could do something like:
> public void processAnnotatedType(@Observes @RequireAnnotations({@Unwraps.class}) ProcessAnnotatedType pat) 
> This could allow the container to take advantage of annotation indexing to improve boot time performance, as well as reducing uneeded processing in the observer.
