Annotation Type Stereotype

@Target(value=ANNOTATION_TYPE)
@Retention(value=CLASS)
public @interface Stereotype

In many systems, use of architectural patterns produces a set of recurring roles. A stereotype allows a framework developer to identify such a role and declare some common metadata for objects with that role in a central place. A stereotype is an annotation, annotated with @Stereotype, that captures several other annotations. For example, the following stereotype defines a @PseudoSingletonComponent annotation, that will act, when applied on a component, just like if @Component and @Instantiate where directly applied on the target component.

     @Component
     @Instantiate
     @Stereotype
     @Target(TYPE)
     @Retention(CLASS)
     public @interface PseudoSingletonComponent {}

 

Usage:

     @PseudoSingletonComponent
     public class HelloWorldComponent {
       // ...
     }

 

Equivalent to:

     @Component
     @Instantiate
     public class HelloWorldComponent {
       // ...
     }
