If no test section yields a true value, then no body section is executed this may be a semantic error if output values are expected from the conditional node. The choice is non-deterministic, unless the test sequence of clauses is specified.If more than one test section yields a true value, only one body section will be executed.If one or more test sections yield a true value, one of the corresponding body sections will be executed. When the conditional node begins execution, the test sections of the clauses are executed. Conditional NodeĪ conditional node is a structured activity node representing an exclusive choice among a number of alternatives.Ī conditional node consists of one or more clauses, each consisting of a test section and a body section. When combined with flows, actions must also satisfy their control and data flow inputs before starting execution. When the sequence node is enabled, its executable nodes are executed in the order specified. Sequence NodeĪ sequence node is a structured activity node that executes its actions in order. The results of the final execution of the test or body are available after execution of the loop is completed. The setup section is executed once on entry to the loop, and the test and body sections are executed repeatedly until the test produces a false value. The test section may precede or follow the body section. Event Final State State Name Initial State Question 12 0/0.A loop node is a constructed activity node representing a loop with setup, test, and body sections.Įach section is a well-nested subregion of an activity whose nodes follow any predecessors of the loop and precede any successors of the loop. Which of the following statements is FALSE? Objects can change state in response to an event An event does NOT have to be based only on time Attributes of an object must change when the object changes state An object does NOT have to change state when a transition "fires" Question 11 0/0.5 pts From the following state transition diagram, identify the missing component. objects can change their state over time. Which of the below is the best example of a return message in a sequence diagram? processPayment[0 Pay(creditcard) Payment Receipt Pay by credit card When drawing an Object Sequence Diagram, which of the below could be in a lifeline box? Ticket Sales System A single email Methods Question 9 0.5/0.5 pts Which of the following components is NOT part of a State Transition Diagram? Transitions Processes States Events Which type should you draw? Object sequence diagrams System sequence diagrams All sequence diagrams 'Black box' sequence diagrams An activation or execution bar in a sequence diagram is represented by - Rectangle Rounded rectangle Dotted straight line Thin rectangle on a lifeline Question 5 0/0.5 pts Which of the following statements about synchronous communication in sequence diagram is true? Synchronous communication is modelled with a half arrowhead With synchronous communication, the sender waits for a response With synchronous communication, the sender does not wait for a response None of these are correct Question 6 0/0.5 pts Within this subject, you are required to draw one type of Sequence Diagram for your workshops and assignments.
