[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2675) Search superclasses of components for @Interceptore

Tue Feb 26 08:13:42 EST 2008

    [ http://jira.jboss.com/jira/browse/JBSEAM-2675?page=comments#action_12400582 ] 

Clint Popetz commented on JBSEAM-2675:
--------------------------------------

Note that if the annotation @Foo with the meta-annotation @Interceptors(SomeInterceptor.class) exists on multiple classes in the ancestry of a class A, then A will be intercepted multiple times by SomeInterceptor.  I considered hashing and removing duplicates, but this would involve inspecting @Foo itself to determine if it has any meta-data that is different for each instance, which seemed problematic.   Also, I'm not sure removing duplicates is always the desired behavior.

(This is again the weird impedance mismatch of annotations with inheritance. )

> Currently Component.initInterceptors doesn't search superclasses of the bean class for an annotation with the @Interceptors meta-annotation.  This patch adds that functionality.
