Annotation Interface ExceptionHandler

@Documented
@Target(METHOD)
@Retention(RUNTIME)
public @interface ExceptionHandler

Marks a method as a exception handler. When exceptions are thrown from methods annotated with annotations listed below, the most appropriate handler is chosen and invoked. In the case that exceptions raised from Task / Callable methods are handled by TaskExceptionHandler / CallableExceptionHandler methods without raising another exceptions, handlers are not invoked.

 @Controller
 class MyController extends AbstractController{
   @Task
   void foo(){
     throw new RuntimeException();
   }

   @ExceptionHandler( "foo" )
   void fooExceptionHandler( RuntimeException e ){
     // Called when the task "foo" raises an exception
   }
 }
 

Supported annotations are:

• OnCreate
• OnPostCreate
• OnDestroy
• OnChange
• OnShow
• OnHide
• OnTime
• OnNotice
• Task
• Callable

• CallableExceptionHandler
