public class UseCase

extends Classifier

The use case construct is used to define the behavior of a system or other semantic entity without revealing the entity’s internal structure. Each use case specifies a sequence of actions, including variants, that the entity can perform, interacting with actors of the entity.

In the metamodel UseCase is a subclass of Classifier, containing a set of Operations and Attributes specifying the sequences of actions performed by an instance of the UseCase. The actions include changes of the state and communications with the environment of the UseCase.

There may be Associations between UseCases and the Actors of the UseCases. Such an Association states that instances of the UseCase and a user playing one of the roles of the Actor communicate with each other. UseCases may be related to other UseCases only by Extends and Uses relationships, i.e. Generalizations stereotyped «extends» or «uses». An Extends relationship denotes the extension of the sequence of one UseCase with the sequence of another one, while Uses relationships denote that UseCases share common behavior.

The realization of a UseCase may be specified by a set of Collaborations, i.e. the Collaborations define how Instances in the system interact to perform the sequence of the UseCase.
