This annotation is used to associate code with usecases. A usecase is a functionality of the system that can be
performed by an end-user, an external system or automatically by the system itself. Typically the implementation of a
usecase contains aspects in different layers of the application and is not directly reflected by grouping units such
as modules or java packages. Therefore this annotation may be used to identify which code belongs to a particular
usecase. Therefore you should define a class, interface, or enum with string constants for the names of your
usecases. The javadoc of these constants shall provide further documentation of the usecase like the detailed
description or links to further documentation.
Note:
This
Annotation is also a
Qualifier for
Cdi.
