combined fragment in sequence diagram

Sequence fragments have been introduced by UML 2.0, which makes it quite easy for the creation and maintenance of an accurate sequence diagram. Format Combined op (operator): applied to the enclosed interaction(s) (some operators require arguments, such as diagrams names, parameters, constants and guards) [guard]: a boolean expression the interaction is executed according to the guard's value diagram name: needed if we want to refer to a diagram defined elsewhere interaction: a (fragment of a) sequence diagram (it can contain other . Alternative combined fragments Alternative combined fragments denoted by Alt operator, it represent a choice of behavior in sequence diagrams. First, a break’s frame has a name box stating “break” instead of “option.”. A UML 2.0 sequence diagram usually consists of a large number of different types of fragments and possibly with nesting. They are used to regroup other constructions (including other Combined Fragments ) into blocks. Figure 7. It can be used for creating and maintaining an authentic sequence diagram. Design infographic, flyer, posters, gift cards, logos, certificates, menus, resumes, and more. UML sequence diagrams are used to show how objects interact in a given situation. Each object also has its timeline represented by a dashed line below the object. The sender that already exist at the start of the interaction are placed at the top of the diagram. Slide 5: Sequence Diagrams Dimensions Time. Found inside – Page 112Interactions, or sequence diagrams, constitute some of the most powerful concepts ... diagram, which are accomplished by what is called combined fragments. Objects take on the responsibility for things like managing data, moving data around in the system, responding to inquiries, and protecting the system. It is also common reusing some interaction between several other interactions. Keeps the Combined Fragment blocks on the diagram, even if they don't contain anything. A message sent from outside the diagram can be represented by a message originating from a filled-in circle (found message in UML) or from a border of the sequence diagram (gate in UML)." [Sequence diagram. The Combined Fragments provide a means to define particular conditions and subprocesses for any sections of lifelines in the Sequence diagram by specifying an area where the conditions or subprocesses apply. The example shows a Sequence diagram with three participating objects: Customer, Order, and the Stock. Eye-catching Sequence Diagram template: Alternative Combined Fragment.
