You can create a lifeline by double-clicking on a diagram or choosing how you present it from the tool palette. UML Sequence Diagrams . The basic syntax for a line in a sequence diagram shows that one participant is sending a message to another participant: Sequence diagrams are a type of interaction diagram which focus on the interaction of a scenario of a given task as observed over time. #staruml #uml Sequence diagrams are sometimes called event diagrams or event scenarios. An important characteristic of a sequence diagram is that time passes from top to bottom : the interaction starts near the top of the diagram and ends at the bottom (i.e. Sequence diagram examples and instruction.

The sequence -> is used to draw a message between two participants. 8 ... loop Loop: the fragment may execute multiple times, and the guard indicates the basis of iteration. Earlier I stated that sequence diagrams are effectively a form of visual coding, or perhaps another way to think of it is that sequence diagrams can be used for very detailed design. If a note contains more than one line, it will not be word-wrapped. As usual, make sure you’ve enabled the UML shape library. Both loops and conditionals use interaction frames, which are ways of marking off a piece of a sequence diagram. Instead, it will be formatted exacty as written.
