| /** |
| * 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 {@literal @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. |
| * <pre> |
| * |
| * @Component |
| * @Instantiate |
| * @Stereotype |
| * @Target(TYPE) |
| * @Retention(CLASS) |
| * public @interface PseudoSingletonComponent {} |
| * |
| * </pre> |
| * |
| * Usage: |
| * <pre> |
| * |
| * @PseudoSingletonComponent |
| * public class HelloWorldComponent { |
| * // ... |
| * } |
| * |
| * </pre> |
| * |
| * Equivalent to: |
| * <pre> |
| * |
| * @Component |
| * @Instantiate |
| * public class HelloWorldComponent { |
| * // ... |
| * } |
| * |
| * </pre> |
