 /**
  * <!-- begin-user-doc -->
  * A representation of the model object '<em><b>Use Case</b></em>'.
  * <!-- end-user-doc -->
  *
  * <!-- begin-model-doc -->
  * A UseCase is a kind of behaviored classifier that represents a declaration of an offered behavior. Each use case specifies some behavior, possibly including variants, that the subject can perform in collaboration with one or more actors. Use cases define the offered behavior of the subject without reference to its internal structure. These behaviors, involving interactions between the actor and the subject, may result in changes to the state of the subject and communications with its environment. A use case can include possible variations of its basic behavior, including exceptional behavior and error handling. The subject of a use case could be a physical system or any other element that may have behavior, such as a component, subsystem or class. Each use case specifies a unit of useful functionality that the subject provides to its users, i.e., a specific way of interacting with the subject. This functionality, which is initiated by an actor, must always be completed for the use case to complete. It is deemed complete if, after its execution, the subject will be in a state in which no further inputs or actions are expected and the use case can be initiated again or in an error state. Use cases can be used both for specification of the (external) requirements on a subject and for the specification of the functionality offered by a subject. Moreover, the use cases also state the requirements the specified subject poses on its environment by defining how they should interact with the subject so that it will be able to perform its services. The behavior of a use case can be described by a specification that is some kind of Behavior (through its ownedBehavior relationship), such as interactions, activities, and state machines, or by pre-conditions and post-conditions as well as by natural language text where appropriate. It may also be described indirectly through a Collaboration that uses the use case and its actors as the classifiers that type its parts. Which of these techniques to use depends on the nature of the use case behavior as well as on the intended reader. These descriptions can be combined. An example of a use case with an associated state machine description is shown in Figure 405.
