Mark Paluch created CDI-451: ------------------------------- Summary: Improve producer method signature capability by accepting qualifier annotations Key: CDI-451 URL: https://issues.jboss.org/browse/CDI-451 Project: CDI Specification Issues Issue Type: Feature Request Components: Beans Reporter: Mark Paluch Priority: Optional CDI supports producer methods which accept the InjectionPoint as argument which allows to access all metadata to the injection point. The InjectionPoint approach adds a certain complexity which is not needed when only qualifier metadata has to be processed. I propose to allow annotation types within the producer method signatures. Code example for a use case: {code} @HttpParam("username") @Inject String username {code} {code} import javax.enterprise.inject.Produces; import javax.enterprise.inject.spi.InjectionPoint; class HttpParams @Produces String getParamValue(HttpParam httpParam) { ServletRequest request = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest(); return request.getParameter(httpParam.value()); // current support looks like: // String getParamValue(InjectionPoint ip) { // return request.getParameter(ip.getAnnotated().getAnnotation(HttpParam.class).value()); } } {code} Producer methods accepting qualifier annotations ensure to have always an annotation instance, this helps to prevent null pointer access since InjectionPoint.getAnnotated().getAnnotation(java.lang.Class<T>) may return null. -- This message was sent by Atlassian JIRA (v6.2.6#6264)
