Use Case View

The controlled controllers mechanism allows the application to be designed around multiple discrete presentation-tier controllers. Related to the Model View Controller (MVC) pattern, the controlled controllers mechanism is a manager of individual MVC controllers. Each controller represents a separate use case and is responsible for managing the dialogue between the user, or actor, and the system for all supported scenarios. The top-level use case model is shown in Figure C-1. The basic flow for accepting and managing a user page request is documented in the sequence diagram of Figure C-2. The sequence diagram for adding controllers to the stack is shown in Figure C-3. Figure C-4 shows how controllers are removed.
