Annotation Type AppInjectionPoint

@Retention(value=RUNTIME)
@Target(value={METHOD,FIELD})
public @interface AppInjectionPoint

Annotates the method that represents an application injection point.

Injection points are points in the application where the server injects platform objects of interest to the application. the injected object is determined from the annotated method signature.

When running in an XVM, the Talon runtime will inject the following types if annotated with @AppInjectionPoint:

• SrvAppLoader
• AepEngine
• AepEngineDescriptor
• AepMessageSender

Example: Injecting into a field

 public class MyApp {
   @AppInjectionPoint
   private AepMessageSender sender;
 }
 

Example: Injecting via a method

 public class MyApp {
   private AepMessageSender sender;
   
   @AppInjectionPoint
   public void setMessageSender(final AepMessageSender sender) {
     this.sender = sender;
   }
 }
 

Example: Injecting into other objects By default Talon only searches for annotations on methods and fields of the application main class. The AppIntrospectionPoints annotation can be used to tell Talon about other objects that should be introspected for annotations.

 public class MyApp {
   private class SomeObject {
   
     @AppInjectionPoint
     private AepMessageSender sender;
     
   }
   
   private final SomeObject someObject = new SomeObject(); 
   
   @AppIntrospectionPoints
   public void getIntrospectedObjects(final Set<Object> introspectionPoints) {
     introspectionPoints.add(someObject);
   }
 }
