Lecture 26 – State machine diagram. In this chapter, the following content will be discussed: UML behavioral diagrams, sequence diagram, UML behavioral diagrams, state machine diagram, elements of a state machine diagram, creating a state machine diagram. | SOFTWARE DESIGN AND ARCHITECTURE LECTURE 26 Review UML behavioral Diagrams Sequence diagram Outline UML Behavioral Diagrams State Machine Diagram Elements of a State Machine Diagram Creating a State Machine Diagram State Machine Diagram Some of the classes in the class diagrams are quite dynamic in that they pass through a variety of states over the course of their existence. For example, a vehicle can change over time from being “new” to “pre-owned,” on the basis of its status with the dealership. State Machine Diagram A behavioral state machine diagram is a dynamic model that shows the different states that a single class passes through during its life in response to events, along with its responses and actions. State Machine Diagram What objects are best used with state diagrams? large, complex objects with a long lifespan domain ("model") objects not useful to do state diagrams for every class in the system! State Machine Diagram Typically, behavioral state machine diagrams are .
