Is @Any supported?

[jervisliu]

Hi, I have following code using @Any:

Map<String, Activity> activites = new HashMap<String, Activity>()

@Inject

void initServices(@Any Instance<Activity> activities) {

    for (Activity activity: activities) {

        activites.put(activity.getNameToken(), activity);

    }

}

Then I have all Activity classes marked as @ApplicationScoped for example:

@ApplicationScoped

public class MyAdminAreaActivity extends Activity {

}

I would like to use this code to have all Activity classes instantiated then get them injected into activities. However during the debug I found activities is empty. I wonder if @Any is already supported in Errai or did I do any wrong? Thanks.

Cheers,

Jervis

This is not yet supported. But will be soon in Errai 2.1. Although, Instance<?> does not exactly work like that.

Instead of doing what you're trying to do, you can simply use the Bean Manager: https://docs.jboss.org/author/display/ERRAI/Client-Side+Bean+Manager

public MyManagedBean {   @Inject IOCBeanManager manager;   public void lookupBean() {     Collection<IOCBeanDef> bean = manager.lookupBeans(Activity.class);     // check to see if the bean exists     for (Activity activityBean : beans) {       // get the instance of the bean       Activity bean = (Activity) activityBean.getInstance();     }   } }
