I know this question is old and I haven't done a search yet, but it made me wonder whether showing branching is even a good idea for sequence diagrams. I always thought the conditions for the sequence were explicitly described in the scenario and thus no …

2014年2月21日 · Sequence diagram describes a set of interactions sequences. opt fragment in diagram means that the diagram describes two possible interactions sequences - one with the interaction in the opt fragment and another without this interaction.

2015年12月28日 · In Sequence Diagrams, The returned object type is indicated by an identifier in the text in each box, such as "user: User" or ":UserDAO".

The observed class is calling update in the observer every 5 seconds in a loop. I need to show this in the sequence diagram. Is there a way to show it looping indefinitely out of sequence as it were? Or does it not make sense in the context of a sequence diagram; should I not include it? Or should I include it in a different type of diagram?

2016年7月4日 · Sequence diagram is good at depicting the sequence of messages flowing from one object to another, how their messages/events are exchanged in what time-order. Notice that sequence diagram may also express conditions, loops and concurrency by using guards, but they are not as intuitive and convenient as those in activity diagram.

When it comes to C++, sequence diagrams are defined in the general sense by the UML specification, which is the same for all object oriented languages. UML is considered a higher-level concept from source code that looks the same for all languages, and the process of converting source code to UML is called code reverse engineering.

As jessehouwing mentioned in his comment, generating sequence diagrams from code (and many other UML generation options) has been removed in VS2015. With the current release, these are the diagrams that can be generated from existing code: To visualize the architecture of a system or existing code, create the following diagrams: Layer Diagrams
