[Uml-devel] fork/join branch/merge difference

[Jens Krüger]

Hi Jonathan,

I looked into the UML reference handbook and I found the following difference:

fork/join is used when the jobs are running simultaneous (concurrent)

branch/merge is used in case of alternate threads.

(see The UML reference manual, page 82)
