- Question: An object of class ReportEmergencyForm is created when object of ReportEmergencyControl sends the «create» message and is destroyed once the EmergencyReportForm has been submitted. In general, the second column of a sequence diagram represents the boundary object with which the actor interacts to initiate the use case (e.g., ReportEmergencyButton). The third column is a control object that manages the rest of the use case (e.g., ReportEmergency– Control). From then on, the control object creates other boundary objects and may interact with other control objects as well (e.g., ManageEmergencyControl). ?
