Annotation Type UpStatus

@Qualifier
 @Target(value={FIELD,PARAMETER,METHOD})
 @Retention(value=RUNTIME)
public @interface UpStatus

A generic binding annotation that can be associated with the up status of an application.

  bind(Boolean.class).annotatedWith(UpStatus.class).toInstance(new AtomicBoolean(true));
  bind(new TypeLiteral() {}>).annotatedWith(UpStatus.class).toInstance(new SomeSupplierThatTellsYouTheUpStatus());

  public class Foo() {
     @Inject
     public Foo(@UpStatus Supplier isUp) {
        System.out.println("Application isUp: " + isUp);
     }
  }
 

If you're using RxJava you can set up an Observable of up status

  bind(new TypeLiteral>() {}>).annotatedWith(UpStatus.class).toInstance(new SomethingThatEmitsChangesInUpStatus());

  public class Foo() {
     @Inject
     public Foo(@UpStatus Observable upStatus) {
         upStatus.subscribe(new Action1() {
             public void call(Boolean status) {
                 System.out.println("Status is now up");
             }
         });
     }
  }
