Title: [solved] Structured Node - Activity
Post by: Henrik Raböse on July 02, 2017, 07:14:22 am

Hi,

how to use this function.
I cannot found any options to set the reference to other diagram / sub-activities.

A tutorial at youtube would be great.

Hi,

When you drag a 'Structured Activity' from the Toolbox to the canvas, you can either create a Simple Composite or from a selection of  'Structured'. See also the online help (F1 in the diagram).

Just give it a try, and you quickly understand it. Drag a 'Structured Activity' from the Toolbox to an Activity Diagram and observe Diagram and Project Browser. With ALT+G you can navigate from Diagram Element to specification in Browser.

'Simple Composite':
It's an Activity which is refined by an Activity Diagram. A useful construct, often called Composite. You will learn to appriciate it. It hides complexity and with a double click you jump into the refinement.

'Other':
Personally, I never use them. If I have e.g. a loop I usually model it as a 'Composite Activity'/'Simple Composite'. The name is then something like 'Loop over all..'. The refinement diagram (composite) contains what inside the loop happens. If you use such a construction you get easy to understand Activity diagrams. If you try to model loops with Case and Merge you soon get a messy diagram. It takes long to understand the sense behind it.
Another possibility is to use <<Stereotypes>> like <<loop>>.



Kind regards,

Helmut

Hi Helmut,

thank you for this answer.
The "Simple Composite" works fine.
