Hello,
I found a documentation describing the different classes and constructors such as (Component part Factory Imp…etc) in my local installation,
I was wondering if there was any “online” version of that open source documentation?
Thanks
Hi,
The starting point for online documentation is the Capella wiki and also the Capella Studio tutorials. The Capella documentation embedded in your Capella install also has some technical information but the online documentation in the wiki is the most up to date.
Regards,
Arnaud
Yes I understand, the 2 links you mentioned indeed help a lot. In one of the pages we even find this:
Getting the Metamodel
Metamodel are defined in ecore files located under plugins ending by *.gen
and checking some .ecore files indeed help finding things like:

Whereas the documentation I saw is like this:
It’s kinda more readable. We want to find instantly all he methods that a Capella Class posseses, and we want to find it inheritances easily.
I guess what I was looking for first, was the online version of these docs (with methods), but now I am looking for the “detailed metamodel description” document (100% java oriented) opposed to the “simplified metamodel api” document made for Python4Capella, which is python/java oriented but not 100% java oriented, and it also lacks everything that is outside Capella kind of (Kithalpha, sirius, GMF,…).
Generally speaking, I find that using the Interpreter window is the most efficient to write scripts using Java. By using the completion, you can see what methods/properties are available on a given object.

I feel like everyone keep using pre used codes and copy paste them (and modify few things using the intereter and/or ctrl+space), without having clear “global centralized and complete” documentations, same as for Document Generation where people keep RE-using older codes.
Some people have probably created some personal docs I wager.
Anyway, this is how It feels for me:
Now considering the competition, it is maybe better, some day in the future? To switch to something like this:
It could ensure the lifespan of Capella?
The balance is probably not for me to say/decide, I am no expert. I might be totally wrong.
Edit: Python4Capella is DEFINTELY helping, it’s a bypass that goes through the barrier.
