I would want an ability to indicate entry and exit points in component diagrams
Here is an example of entry/exit points from IBM (see the outside OrderEntry, leading into Store; Account, leading outside the Store):
Source: https://www.ibm.com/developerworks/rational/library/dec04/bell/index.html
I see this is working for State diagrams:
@startuml
state a {
}
[*]->a
@enduml
I'd like to be able to use the same syntax for component diagrams:
@startuml
component a {
}
[*]->a
@enduml
Also, I did not find a syntax for exit point (neither in state nor in component diagrams)
Not sure, but probably entry/exit points can be better implemented as "hanging arrows":
->a: entry
a->: exit
The arrow tip should be variable too.
Additionally, it would be useful to have an ability to add a note to entry and exit points. Not to the arrows, but the the points themselves.
