![]() Loops: A repetition or loop within a sequence diagram is depicted as a rectangle. ![]() Sequence Diagram Destroying Objects Diagram Lifelines: Lifelines are vertical dashed lines that indicate the object's presence over time.ĭestroying Objects: Objects can be terminated early using an arrow labeled '>' that points to an X. Asynchronous messages are sent from an object that will not wait for a response from the receiver before continuing its tasks. Use half-arrowed lines to represent asynchronous messages. Messages: Messages are arrows that represent communication between objects. Use the UML object symbol to illustrate class roles, but don't list object attributes.Īctivation: Activation boxes represent the time an object needs to complete a task. Objects are represented exactly how they have been represented in all UML diagrams-as rectangles with the underlined class name within the rectangle.īasic Sequence Diagram symbols and notations:Ĭlass Role: Class roles describe the way an object will behave in context. A sequence diagram is made up of objects and messages. This allows the specification of simple runtime scenarios in a graphical manner. We are here to help you in your Assignment related to UML Sequence Diagram.Ī sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. ![]() Sequence diagrams represent the interactions among classes in terms of an exchange of messages over time.
