[JBoss JIRA] (CDI-485) Provide literals for built-in annotations

by Martin Kouba (JIRA)

[ https://issues.jboss.org/browse/CDI-485?page=com.atlassian.jira.plugin.sy... ] Martin Kouba updated CDI-485: ----------------------------- Description: Annotation literals are often useful and therefore many projects implement them themselves. For example: https://github.com/apache/deltaspike/blob/master/deltaspike/core/api/src/... https://github.com/weld/core/blob/master/impl/src/main/java/org/jboss/wel... https://github.com/forge/furnace-cdi/blob/master/impl/src/main/java/org/j... https://github.com/astefanutti/metrics-cdi/blob/master/impl/src/main/java... to name a few. It would be nice to provide these within the CDI API, e.g: {code:JAVA} @Target( { TYPE, METHOD, PARAMETER, FIELD }) @Retention(RUNTIME) @Documented @Qualifier public @interface Default { @SuppressWarnings("all") final class Literal extends AnnotationLiteral<Default> implements Default { private Literal() { } } final Default INSTANCE = new Literal(); } {code} was: Annotation literals are often useful and therefore many projects implement them themselves.

[JBoss JIRA] (CDI-580) Allow interceptors and decorators to be applied to the return value of a producer method

by Emily Jiang (JIRA)

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Emily Jiang commented on CDI-580: --------------------------------- If it is possible to support interceptors on a producer's returned value, I would prefer the following: @Produces(interceptors={MyInterceptor.class}) as it is clear that MyInterceptor is for the producer's return value. > Allow interceptors and decorators to be applied to the return value of a producer method > ---------------------------------------------------------------------------------------- > > Key: CDI-580 > URL: https://issues.jboss.org/browse/CDI-580 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Beans > Affects Versions: 2.0-EDR1 > Reporter: Mark Struberg > > Currently the spec explicitly disallows to apply interceptors and decorators to contextual instances created by producer fields and producer methods. > if you add an Interceptor annotation to a producer method then only the invocation of the producermethod gets intercepted.

[JBoss JIRA] (CDI-515) Allow to obtain Bean metadata from javax.enterprise.inject.Instance

by Antoine Sabot-Durand (JIRA)

[ https://issues.jboss.org/browse/CDI-515?page=com.atlassian.jira.plugin.sy... ] Antoine Sabot-Durand commented on CDI-515: ------------------------------------------ I don't see that limited to instances provided by a given Instance<>. Like you can use Instance.destroy() to destroy any instance today. A use case could be: obtaining metadata for a bean defined by a class you don't own. Today we store all bean instances to manage their lifecycle, so how difficult would it be to compare a given instance with these stored instances and retrieving the bean used to generated it. It's probably costly but could be very useful. > Allow to obtain Bean metadata from javax.enterprise.inject.Instance > ------------------------------------------------------------------- > > Key: CDI-515 > URL: https://issues.jboss.org/browse/CDI-515 > Project: CDI Specification Issues > Issue Type: Feature Request > Affects Versions: 1.2.Final > Reporter: Martin Kouba > Assignee: Martin Kouba > Fix For: 2.0 (proposed) > > > Sometimes it might be useful to obtain Bean metadata from the {{javax.enterprise.inject.Instance}} (similarly as 5.5.8. Bean metadata). The method could be named {{getBean()}} and should have similar restrictions like {{get()}} (e.g. throw {{UnsatisfiedResolutionException}} if appropriate). -- This message was sent by Atlassian JIRA (v6.4.11#64026)

by Romain Manni-Bucau (JIRA)

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Romain Manni-Bucau commented on CDI-580: ---------------------------------------- [~mkouba] agree it would work most of the time so the feature does worth it. BTW {code} @Produces(interceptors={MyInterceptor.class}) {code} is quite odd compared to the "natural": {code} @Interceptors(MyInterceptor.class) // this is the natural way to set interceptors IMHO @Produces(superFlagToRenameActivatingProxying = true) // activate interceptors and decorators {code} > Allow interceptors and decorators to be applied to the return value of a producer method > ---------------------------------------------------------------------------------------- > > Key: CDI-580 > URL: https://issues.jboss.org/browse/CDI-580 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Beans > Affects Versions: 2.0-EDR1 > Reporter: Mark Struberg > > Currently the spec explicitly disallows to apply interceptors and decorators to contextual instances created by producer fields and producer methods. > if you add an Interceptor annotation to a producer method then only the invocation of the producermethod gets intercepted.

[JBoss JIRA] (CDI-580) Allow interceptors and decorators to be applied to the return value of a producer method

by John Ament (JIRA)

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] John Ament commented on CDI-580: -------------------------------- [~martinkouba] respectfully I disagree. Good development practices around integration isolation say that I really only have one entry point to an external lib. It may be a use case for producer methods/fields, but its not the only one. In that specific case, I typically don't even provide that entry point as a bean. In the main thing I've been working on, the main use for a producer method is to provide convenience to a default implementation of some interface, based on outside configuration. In this case, I'm usually providing an instance of a bean with a different set of qualifiers for that look up. > Allow interceptors and decorators to be applied to the return value of a producer method > ---------------------------------------------------------------------------------------- > > Key: CDI-580 > URL: https://issues.jboss.org/browse/CDI-580 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Beans > Affects Versions: 2.0-EDR1 > Reporter: Mark Struberg > > Currently the spec explicitly disallows to apply interceptors and decorators to contextual instances created by producer fields and producer methods. > if you add an Interceptor annotation to a producer method then only the invocation of the producermethod gets intercepted.

by Martin Kouba (JIRA)

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Martin Kouba commented on CDI-580: ---------------------------------- Yep, but it's not very flexible as you can only associate the interceptor at the class level (all methods). This may be ok in most cases though. > Allow interceptors and decorators to be applied to the return value of a producer method > ---------------------------------------------------------------------------------------- > > Key: CDI-580 > URL: https://issues.jboss.org/browse/CDI-580 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Beans > Affects Versions: 2.0-EDR1 > Reporter: Mark Struberg > > Currently the spec explicitly disallows to apply interceptors and decorators to contextual instances created by producer fields and producer methods. > if you add an Interceptor annotation to a producer method then only the invocation of the producermethod gets intercepted.
