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

by Martin Kouba (JIRA)

[ https://issues.jboss.org/browse/CDI-515?page=com.atlassian.jira.plugin.sy... ] Martin Kouba commented on CDI-515: ---------------------------------- That would be way more complicated if possible at all. Let's assume you have two producers for dependent {{Foo}} and each specifies a different qualifer. Then you inject {{Instance<Foo>}} and select Instance for qualifier {{@A}} and get instance of Foo, and select Instance for qualifier {{@B}} and get instance of Foo. How would you differentiate these instances? What happens if you pass Foo {{@B}} reference to the Instance for Foo {{@A}}? You would have to track all the instances provied by each Instance. > 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)

[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: ------------------------------------------ If we want to provide the same service than in 5.5.8 we need to provide a {{getBean(T)}} to allow retrieving a bean from one of its instance. IMO this would be far more 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.

by Martin Kouba (JIRA)

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Martin Kouba commented on CDI-580: ---------------------------------- I remember that this has been discussed many times and the main problem was how to declare the interceptor bindings - because the "product" class usually cannot be modified. > Allow interceptors and decorators to be applied to producer methods > ------------------------------------------------------------------- > > 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 Mark Struberg (JIRA)

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Mark Struberg commented on CDI-580: ----------------------------------- Yes, you could have an @Transactional which needs to get applied for the method invocation itself, and another interceptor, say @Logging, which gets applied to the produced instance. > Allow interceptors and decorators to be applied to producer methods > ------------------------------------------------------------------- > > 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.

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Romain Manni-Bucau commented on CDI-580: ---------------------------------------- I dont think so, the flag will be for new methods so the user controls it.

[ https://issues.jboss.org/browse/CDI-580?page=com.atlassian.jira.plugin.sy... ] Stephan Knitelius commented on CDI-580: --------------------------------------- Maybe we should differentiate between Interceptors applied to the producer method and the created bean.
