sequence diagram lifeline

The lifeline name is underlined. When an underline is used, it means that the lifeline in a sequence diagram represents a specific entity of a class, not a specific entity of a specific type (for example, a role ). The instance name of the sequence chart is underlined, but

instance name in UML is underlined. The class or Instance name can be omitted in the object graph. The rectangle of each class graph corresponds to a separate instance. The UML chart highlighted in the instance name. The class or Instance name may be omitted from the object chart, as long as the meaning of the chart is still clear. Sequence Chart Class charts and object graphs are static model views. The interaction

passed between the object classes that complete a behavior and those object classes. A sequence diagram is an interaction diagram that emphasizes the time order of messages. A sequence diagram describes the chronological order in which messages are sent between objects, and

. The class meta-role is represented by a lifeline. When an object exists, the role uses a dotted line. When the object is activated, the lifeline is a dual line. Messages are represented by arrows from the lifeline of an object to the lifeline of another object. Arrows are arranged from top to bottom in chronological

both classes can be associated with one or more other classes. A class chart can be integrated with many other concepts, which will be introduced in subsequent articles in this series. Back to Top Sequence Diagram The sequence diagram

The rectangle of each class graph corresponds to a separate instance. The UML chart highlighted in the instance name. The class or Instance name may be omitted from the object chart, as long as the meaning of the chart is still clear. Sequence Chart Class charts and

Event Sequence and generate expected output. The focus is not on the message itself, but on the order in which messages are generated. However, most sequence diagrams indicate what messages are transmitted between System Objects and the order in which they occur. The figure transmits information in the horizontal and vertical dimensions: the vertical dimension indicates the time

the concurrent activities. Both the branch line and the confluence line are expressed by a bold horizontal or vertical line segment (synchronous line ). 14. Sequence Diagram 1. Definition: sequence diagram, also known as sequence diagr
