Non-EMF Diagram Saving (only view information) [message #991263]

Hi again,

sorry for bothering you guys with so many questions, but it's apparently really hard to accomplish things when you aren't using a EMF-model, at least for me.

I'm trying to save only the view information.
The entire process is:

Load:
-- load model (use my own loading mechanism)
-- load view information (use Graphiti)
if there is none, create one.
-- hook these things together

Save:
-- save model (use my own loading mechanism)
-- save view information (use Graphiti)

I found different threads dealing with separating model and view information, but everything is based on EMF and I don't really see a solution for my problem.

Should I use the Independence Solver to save this information by just saving the underlying map?
Or just write my own saving mechanism in order to save what I need?

Help is highly appreciated, I'm a bit lost at the moment Sad

Open for any pointers, best practices or suggestions Smile

Tim,

it seems there should be an example dealing with non-EMF domain models...

In general you should simply let the diagram editor persist and load the EMF
parts (in the non-EMF case only the diagram itself). Within this model you
can have properties that allow your independence solver to identify the
domain objects that belong to the shapes on the diagram. Therefore there
should be no need to persist the mapping information in the independence
solver. Your save logic should in addition only care about persisting your
non-EMF domain model.
