[cdi-dev] [JBoss JIRA] (CDI-481) Introduce AnnotatedParameter.getJavaParameter()

[Romain Manni-Bucau (JIRA)]

    [ https://issues.jboss.org/browse/CDI-481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004040#comment-13004040 ] 

Romain Manni-Bucau commented on CDI-481:
----------------------------------------

Yep. If you think to an extension allowing kind of dynamic calls it can use then names instead of index or type (which are not enough). For instance:

{code}
@PreSecurity("authenticator.login(username, password)
public Data getSensitiveData() {
  // ...
}

// ...

@Named
public class Authenticator {
    public boolean login(String user, String pwd) {
        return true; 
    }
}
{code}

> Make it possible to obtain the Java Reflection object representing the parameter. This is in line with
> AnnotatedField.getJavaMember()
> AnnotatedMethod.getJavaMember()
> AnnotatedConstructor.getJavaMember()
> Can be implemented as a default method such as:
> {code:JAVA}
> default Parameter getJavaParameter() {
>         Member member = getDeclaringCallable().getJavaMember();
>         if (!(member instanceof Executable)) {
>             throw new IllegalStateException("Parameter does not belong to an executable " + member);
>         }
>         Executable executable = (Executable) member;
>         return executable.getParameters()[getPosition()];
>     }
> {code}
