Asynchronous messages are sent from an object that will not wait for a response from the receiver before continuing its tasks. Use half-arrowed lines to represent asynchronous messages. Messages are arrows that represent communication between objects. When an object is busy executing a process or waiting for a reply message, use a thin gray rectangle placed vertically on its lifeline. Use the UML object symbol to illustrate class roles, but don't list object attributes.Īctivation boxes represent the time an object needs to complete a task.

Seen as a 2-dimensional document such rendering appears more confusing to me than if logic ('alt' statements) was rendered close to those objects it actually belongs to. The (still simplified) example below renders all 'alt' statements as horizontally global. In complex documentations as well as in complex source code I'd like to see related artifacts show up as close as possible (as long as useful). ![]() Programming books and articles such as the linked one rarely present examples of a complexity where documentation gets its relevance just because of the complexity. Note over C: proposal: allow 'dashed' arrows to cross for the reply. Note over C: How could I let those arrows *cross* the border\nof that 'alt' block instead of enlarging it ? 7 participants all calling each other\nconditioned by 'alt' conditions:\nall 'alt' blocks become 'global': what a mess ! Note over C: this simplified example still looks pretty\nnow think of e.g. Note over C: reason (my guess): the arrows between B,C and D Note over C: but the logic appears all over B,C and D Note over B: the alt block visually includes B\nbut B is not part of the logic\n -> bad!Īlt this alt logic is coded exclusively in 'C' Note over C: some if-else logic in C should be horizontally limited to its scope: 'C' Is there any way to control the horizontal size of such 'alt' blocks ? I now kind of adapt the logic I want to document just in order to get my diagrams, which is of course not what documentation should do. Unfortunately that makes the diagram unreadable. Since routines may have multiple calls to other participants and as well have more than one return statement my 'alt' blocks are printed much bigger than I'd like to see: they include all participants called from within the 'alt' and all callers being returned to from within the 'alt' block. Unfortunately the size of these alt blocks seems to be determined as well by all arrows within an 'alt' and its closing 'end' statement. It appears essential that within 'participants' some logic needs to be expressed.Ĭurrently I am using 'alt'. I am about to document quite some procedures using sequence diagrams. ![]()
