Jozef Hartinger created DELTASPIKE-783: ------------------------------------------
Summary: Use @WithAnnotations Key: DELTASPIKE-783 URL: https://issues.apache.org/jira/browse/DELTASPIKE-783 Project: DeltaSpike Issue Type: Improvement Affects Versions: 1.1.0 Reporter: Jozef Hartinger Make use of CDI's @WithAnnotations feature. Each extension that does something like: {code:JAVA} <X> void processAnnotatedType(@Observes ProcessAnnotatedType<X> event) { if (!event.getAnnotatedType().isAnnotationPresent(Foo.class)) { return; } // ... {code} can be extended to: {code:JAVA} <X> void processAnnotatedType(@Observes @WithAnnotations(Foo.class) ProcessAnnotatedType<X> event) { if (!event.getAnnotatedType().isAnnotationPresent(Foo.class)) { return; } // ... {code} This can yield performance boost in CDI 1.1+ environment because: 1) the observer method will be only called for annotated types that have the annotation, not for all the types in the deployment 2) the container may not event need to load the annotated type and its class at all if there are no observers requesting the type and the type does not represent a bean. In addition, this works nice in CDI 1.0 environment where the class definition for the annotation is not be found and is ignored. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
