My company's source designs are drawn in standard engineer's "freestyle" form showing connected boxes (=processes/"actions") that also "give an idea about flow and dependency". On such a diagram, there is marked a named 'entry point' to the start of a sequence of processes. This 'entry point' is either:
(1) The name of a wrapper, where all that the wrapper does is to call the "real" boxes (=processes/"actions") that actually do something
(2) Imaginary, where the 'entry point' names the start of a sequence of boxes (processes/"actions").
But instead of the 'entry point' being drawn as a comment, the engineer drew the 'entry point' as a box looking the same as a "real" box (=process/"action").
As I understand things, UML provides no such thing as an 'entry point' element. UML provides a StructuredActivityNode action to wrap all the activities and I can use that. Or I can mark the 'entry point' as a comment. Correct?Thanks,
