Missing features for Functional Chains about py-capellambse HOT 3 CLOSED

I was able to implement:
• Model.la.all_functional_chains is not implemented
• Model.la.all_component_exchanges[x].Kind == [UNSET | ASSEMBLY | DELEGATION | FLOW] missing
• Model.la.all_functions[x].Kind == [DUPLICATE | FUNCTION | SPLIT | ROUTE | SELECT | GATHER] missing

The others are a bit unclear for me. In FunctionalChain diagrams one is able to describe the FunctionalChain with Functions, Exchanges, ControlNodes and SequenceLinks. One can reference other chains, but there is no nesting. What can be achieved is to create a new FunctionalChain underneath the existing Chain. But I don't see how this is then an involvement. Usually Capella manages involvements via an extra dummy XML element. Then how can you involve Components here? And last: what is the difference between involved and involving?

Cheers

I need to look into the comment further, but quick answer to the last question: involved / involving are the two different directions of the relationship.

Heating water is involved in making coffee

Making coffee involves heating water

It is clearer for realized/ realizing or deployed/ deploying for me tbh.

Thanks for the support, cheers

Let me try to answer your questions.

"One can reference other chains, but there is no nesting."
This is correct and what was meant here. When I understand it correctly this is modelled inside Capella as 'Functional Chain Reference'. The term nesting was not really correct when phrasing the problem.

"Usually Capella manages involvements via an extra dummy XML element. Then how can you involve Components here?"
Here I can't help. I have no knowledge about the XML representation of the model.

"And last: what is the difference between involved and involving?"
These terms just refer to the two directions you can look at a functional chain involvement by another functional chain. It is comparable with the parent - owned component relation that exists for logical components.

involved: one functional chain B can involve (make use of) several other functional chains (A, D)) and hence are visible within the LFCD for functional chain B. This property gives a list of all functional chains (A,D) that are used (involved) in one functional chain B.

involving: one functional chain A can be involved by several other functional chains B/C, which means it is visible in several different LFCDs (one for B and one for C). This property gives a list of all functional chains (B,C) that involve functional chain A.

B involves A
B involves D
A is involved by B
D is involved by B
C involves A
A is involved by C

I hope this helps a little.
